Title: 3120 big bore kit
Post by: mcbob on July 02, 2013, 06:48:21 pm
Well fellas as they don't love me anymore at aborting.com jealousey is a pain I know I have purchased the Varney 3120 cylinder assy to bolt to my rebuilt 3120 ... yes I may have paid too much in your eyes but hey its done and now being rebored and a new piston supplied hopefully to interest a few who like to see a little history preserved

I'm a idiot so I removed all my pics

The cylinder is due here in a few weeks should work out to be an interesting project

I used to think the 66mm bore was big. Now I am hearing about 72mm bore on the 48mm stroke saws.  That was a new one to me but trust in who told me.

Just trying to figure out this 72mm. Wonder if maybe it was a cast cylinder or  ??

Dan Duncan from KY R.I.P.  handing me my azz in 2009 in 10x10 poplar.  1st place him and like 5th for me.  My 1st run on the husky and started it on idle to help me stop the wheelie when it was on throttle like normal.

Well coming from an aussie who races regularly, I thought your run was ok, I would not say Cull Operator at all. I have never done that style of racing but know enough to know its harder than it looks.
Sometimes even your best run isn't good enough for lots of reasons.
I have threatened to have a go for years at that style, if I did and videoed it you guys would get a laugh for sure.

edit,,,
forgot to add,,, we tried a simular style back in the 90's which only ran for 1 season.
We had cold start with hands on top of block, start and bore centre 1st followed by down and up, (same as our regular practice) followed by down then up cuts to finish (3 disks) and all inside 4 inches.
The object as we tried this was to even up the open hot saws, we only did it in open speed running in a 14 inch block.
The end result was the better operators with better saws just won by bigger margins and we had many complaints regarding safety so we all agreed to stop it and go back to our normal practice.

Listen Bob, I do not and have never called any man a '' cull operator'' as that term is not used by any of us racing aussies.
What I have called you is simply facts as what you type is usually not fact just construed nonsense or just plain lies.
I have said it before and I will say it again, we as in all the racing fraternity are glad you were removed from competition, and yet you still pretend you are part of it and act like you will step in at any moment.
We race a bloody lot each year, you do not.

Your spot on C4F, I thought that was ok for a weekend run, and for doodlebug to say what he said was simply silly.
He is an aussie, best thing is we don't see him anywhere near the arenas these days and havn't for years, only flapping on forums.

like I said before , make sure your piston clearance is set proper as that should have a cast liner in it , Rings ?, it should be ring if your using a race piston

Mcbob I have built more than a few of those motors for other people , not sure who ported your jug but you have to really watch the intake side on these , there is not much for the intake skirt on the piston to run on so they break off and that in most cases breaks the sleeve as well

Post by: EHP on August 24, 2013, 01:22:19 pm
So I see a new sleeve in the picture , did it get put in ?  and what width is the piston skirt on intake side compared to port width , as I can see the intake port has taken a beating in the pictures and I'm sure the intake skirt took a hell of alot more of a beating , If it had a chrome bore so it could run a tighter clearance I would be alot happier than running a sleeve cause the clearance is alot more and that leads to more intake trouble as the intake side of the piston always takes a beating

All this has me thinking about the 3120 sitting in my garage...
Thing isI don't have a tree in the neighborhood that the Jonsered 2159 or the 670 won't take care of....  And I haven't seen a real chainsaw race since I left Oregon 25yrs ago  :-(
Loves me a good timber carnival.  Wish my son could be growing up with them like I did...   Timber Tina's show at the state fair is as close as we come. It's kinda fun but....  Let's just say it's lacking!

Sadly you are right Kevin, nothing has changed since I 1st started seeing this type of thread by this man.
So many hours on forums and nothing to show in the actual race arena.  Its easy to tell stories, not so easy to do against real competitors who have the skills and knowledge to make it happen.

Another point, we all run a set of saws to get through the race programs, e.g. we run a different saw for each event, starting with Modified pro U77cc through to open hot saw, a big commitment in itself. No one turns up with 1 saw to go in 1 event. Another point of importance, competitors must nominate to get a run, so if the competitor has not received acceptance or conformation by the organisers prior to the event, he or she does not race.

We run invitational events regularly, some organisers do invitation only events which only excepts the top 8 or 10 competitors from each state, it depends on what the organisers need to satisfy the sponcer's  and sometimes sponcers want certain competitors present. Yes we too do invitational's to keep the unwanted out but, there is a lot more to why we do that than the obviouse.

as I said before there's other places to race besides the mid north coast .................. anyway who needs you ?

Just noticed this,,,, way to go Bobby, posting more bull sh#t every day, that's all you have except a chip on your shoulder.
You were part of the association, I wasn't the one who decided to remove you, it was a Unna minas decision I totally agreed on, then acted appropriately with the backing of the association.
The whole of the association records are at my place in filing cabinets, so I have all the records including your actual placing's in the few runs you made (not near as impressive as you want forum viewers to believe).
I'm not hitler, just an administrator, committee man, sponcer, competitor trying to protect our sport from lying fools like you.
Our association is only part of the organised calendar events running from Sydney through to top of QLD.
South of Sydney has talent as well, I know and are still in constant contact with the best down there, thankfully  they don't carry on like you and they know if they ever decide to race again, they will be welcome with us.
So you go and **** off to where ever there is a small weekend run away from the regular race boys, big note yourself to them, I bet those boys beat you just the same. Then we will see if you get invited back the following year, or try QLD, see if they let you race.
No one needs me,,,,, but you sure got a bloody lot of mileage from me, something you could not ever do yourself.
PS,,,, I have you blocked here as well, I saw this post of yours by mistake

Thanks Neil for such an interesting and totally enjoyable response I read it daily with pleasure ................. pity you take things literally and to the extreme what started out as a stir certainly got your blood up quick just what I wanted and know now just how much it pee's you off .............. i' never said I was impressive I said I was out for a day of fun and I was not competitive which just pee'd you off even more we don't all need the killer instinct you have enough to pee an army off.

As regards getting great mileage from you loved it and got sucked in only too quickly and you served your purpose show that after all this time your billy carts haven't got that much quicker and you not me proved that
 
And on another occasion when your mate is running his NOS setup he got beaten by you ..... as you said he must have run outta gas if he remembered to activate it Ha ha ha

As regards others who race but not with your gang its their decision and as shown they prefer a more peaceful day out away from you and your over bearing ways plus I notice you don't venture down their way yourself

Sorry for not responding sooner EHP and yes if after 20 odd years of this saw being around i'd expect that you would have to know a lot more about it than maybe I will ever know and there's only so many combinations it can be in, i'm just deciding which route I will take but 3160 sounds good to me maybe if I can get it organised and  it could be used .............. just depends on how many pennies I can save up.

the 3160 is a 090 jug mounted on a 3120 crankcase , its nothing new , Marcel built a couple in the later 90's , these are 66mm bore , I built a while ago a 72mm bore motor and it ran pretty good but starting the dam thing was unreal so I scrape the motor , if you were over the block it would of been pretty good but cold start  no way

No Ed you are right, no competitor who has actually met him would ever be worried about him.
I'm not sure on our regular competing numbers at present but a quick guess is 90 - 100 between Sydney and the top of QLD.
Thank god the regular racers don't feel the need to start a thread every time they decide to change a spark plug, they simply race and enjoy what comes with this physical sport we choose and do not need to make up stories to gain attention,,,, they already have it.

Kevin, I do have some better pics of the old twin, I sold it off years ago to another NSW stall ward who run it for a few seasons.
I found some old video footage some time back, in the 90's / early 00's we never took video footage like today.
Most competitors video each run to find mistakes but in those days it wasn't so important. I will have to cut out a few runs I made with it.

I don't have any skin in this one. The thread started good but has went down hill from there.  That's all I am saying I am here to help others as I can and learn some along the way. I will say this though EHP is very quick when it come to work saws and race/hot saws. I am pretty sure he is trying to help.

Jason i'm not having a go at EHP as I said yes he'll know more than I will possibly ever know but at least i'm having a go better than the knockers .... now it might prove a bit of real competition regardless of who the operator is

Well the crankcase assy arrived for my second 31?? this morning now it off to the machine shop to get a few mods done and my stroker crank isn't that far away either it's due early November from the states.

Note to Neil the saw will be cleverly disquised with a potato bag covering it.
