Title: new stihl 024 mahle SCUFFING?????????
Post by: CATDIESEL on January 27, 2013, 08:53:55 pm
hello all, new to this particular forum,and i have an issue.

i recently bought 2 new NOS 024 mahle P/C kits. i installed the first one today, and the saw is up and running great. i washed the cylinder well, and lubed it with stihl ultra prior to assembly. i also vac./pressure checked things prior to start-up. my question is this, should there be a tiny amount of scuffing as the P/C break in? i heat cycled the engine twice for 2-3 mins, and then pulled the muffler to check on things. there appears to be some very light scuff marks in the cylinder. is this normal? i shoved a rag in there on a plastic stick, and it seems to wipe away as if it is just the oil on the cyl. wall. i have been using saws for 30yrs, and usually sell/trade/or junk them once they are worn out. i am starting to slow down a little in life, and have recently enjoyed giving these old saws new life again, it is very good therapy for me.  thanks to all!

It's not unusual to find at least a few scuff marks which could be just honing marks ,a little bit of dust or the rings seating in .If you look at the new rings with a jewlers loupe you'll find out they aren't as mirror smooth as they might appear to the naked eye .

this saw runs perfect, starts hot or cold in 1 pull. seems to pull really well in the wood. it has about 15mins. time on the new top end. it seems to want to only pull 13,100 out of the wood. any leaner and it won't four stroke. will the rpm's improve as the rings set in?

Doubtfull out of the wood which really doesn't mean much except noise .What it pulls in the wood is what counts .Yeah it should improve a little with run time .

About the only way you can safely run it higher is by raising the ex time opening but to do so you'll have to pep up the compression and increase the fuel rate .It's kind of a fine line because you really can't do just a portion of a soup job without doing the rest.

If the thing runs okay just leave well enough alone. An 024 is lacking about a half a cubic inch to really consider for a 3 cube cookie cutter in my opinion .Neat little saw though .

RPM issue solved!!!!   i used a new 026/wt194 carb on this saw. for some reason the throttle rod was only opening the butterfly about 80-85%. problem fixed, and she is still four stroking nicely @ 13,800-14,000. now i feel it runs like it should.

can't imagine that nasty saly water does anything any good!

Over in that end of the lake, the water is not very salty but even just fresh water would be bad enough.

I'm sure he does not take the covers off and clean it out when he is done. It just sets up on the swamp buggy in the weather until the next time he needs it.

That series is so sensationalized it's just not even believable .Now take old Shelby .Doesn't have a pot to pee in nor a window to throw it out .Yet he always seems to come up with jet boats ,log barges and  wad of money to buy stuff .All this while his nutty cousin tries to stick him with an arrow like he was Robin Hood or some such stupid nonsense .Balderdash !

Shelby the WILD MAN

If he had a pot and window to throw it out of, once it was full and he threw it out - pot and all - rather than pouring it out - he'd never go get it.

That jet boat carcass was on that property across from Lee's landing long before Shelby came along. You can see it on the old 2007 Google map. It appears to have a new small block in it this season.

That swamp buggy had sat out in the marsh since Katrina until the film crew bought it for him. It has a 4 cylinder aircooled Duetz with hydrostatic skid steer drive. The little hydraulic winch is much too small for snaking logs.

Towards the end of July 2 years ago he had a big accident in that jet boat when he hit a flat boat 2 miles South of Lee's landing in a curve of Bedico Creek. I think there were several cuts and bruises? Most people attribute it to going too fast on that curvy creek?

Well when the "Bush Weasel " was here a few years ago he commented on some of that high line stuff they do in the western states and how they carry on like idiots on that show .

If people got yelled and screamed at like those idiots do the whole crew would pull the pin .I've seen it happen on construction jobs and I imagine loggers are just as bull headed .Nobody has to put up with abuse like that .
