alright! sorry for the delay, but a couple of equipment failures at work and the junk my friends like to "keep running" is enough to drive me up the wall :)
the boot came in a couple few weeks ago, it's quite a bit bigger than the little booty the 2800's come with. i still need to get a kit for the carb (thought i had ordered or had one but no dice). i'll be using the same saw for the testing, the same one in this thread. both saws run the same, at least from what i can tell by holding onto them in the wood. they are muffler modded, but that shouldn't be an issue. i'll have something by the weekend, i need to get some wood. something better than the left over punky ash and elm i have here ;D

I was thinking of this yesterday while buttoning up the 3500 60cc.
 Had a bigger boot and carb right there. But I would have needed to switch the topends on my pp365 to make them equals to compare.
 365 top was wounded at one time and I rednecked it.

ok! here we go :)
as you can see, there is a huge difference in the dia. of the boot.

now don't take the measurments as bang on. these thin rubber boots are a little squishy



ain't no way it'll fit in the handle without some grinding



time for the "redneck machine shop" :)



gotta remove the inserts. use the studs and give a tug and wiggle. they slide right out. i used the original hadware as i didn't see a reason the use the bigger saws stuff. works perfectly fine.


now bigger!


gotta shave them inserts. if not, they'll rub against the boot.


it was at this time a couple friends showed up. they smelled of booze and were a little wobbly. but in good humor for a change.
they liked the plastic shavings from the handle i drilled out for the boot and decided to see what they'd look like with hair ::)


they think they're sooooo funny when they're drunk :)

look! it fits!


carb size difference

i used the fuel pump cover off the small carb to use the better barbed fitting. i also had to shorten the fuel inlet so the airfilter would fit without crimping the line. yeah. the fuel line was a pain to put on that bigger barb ;)

had to make the back plate more open


deffinatly more open now!



it's all back together now. just waiting on the vids to upload. took the first vid this morning of the saw with the small boot. did the swap and made the second vid this afternoon. it isn't 100% in the second vid. i'm pretty sure the carb has some crap in it somewhere i missed. it will barely 4 stroke and the throttle response is a little slow. the throttle response could be slow due to the carb being too big for the engine though, so i need to do some fiddling.
AAAAAND! all i had around to cut was some 2 year old ash that was 5" dia. not a very good cut test, but it's all i could muster up.

alright, here's the vids :)
here's the first vid. stock intake and carb.
https://www.youtube.com/watch?v=wckTyahB8Wg

here's the same saw with the 3450 carb and boot.
https://www.youtube.com/watch?v=DegNr-rOEp0
the saw was 4 stroking, but just barely. at the end of the vid i did tune it more rich and got more 4 stroke out of it, but it still isn't where i want it.
the wood was the only crap i could round up for this. it's 2 year dry ash, 5" dia, maybe slightly bigger. actualy pretty hard.

pulled the carb last night and sure enough the high side had some gunk stuck in the port the is fed from the metering side. a quick shot of non-chlorinated brake cleaner took care of it. threw it all back together and it does sound nice at 12200. i'm going to try it today with a flocked air filter to see the difference in them :)

So what are the gains in the cut are you seeing from small set up to bigger 330 set up?

from what i could tell in that HUUUUUGE log :D, it did hold more rpm's in the cut. how much i have no idea as i can't hold the tach and saw and cut. sort of like chewing gum and walking :) throttle response between boots/carbs is now pretty much the same. i need to get out to kristians house to get some wood. most of anything i have here goes to testing "customers" saws. and always seems to be in short supply.
suppose i could add a piece of velcro on the top cover....
might actually try that next weekend.
the saw does want to 4 stroke nicely at 12300rpm, where as the smaller carb/boot wanted to start getting lean sounding at 11900rpm.
i need to run the saw more, and get bigger wood to see if the switch was actually worth it or not.

HAAAAAALLOOOOOOOOO OUT THAAAAR! :)
had a couple days out with the 2800 this week. friend ended up with a 3/4 ton truck and trailer of ash and elm (the stinky swamp stuff) and some poplar. most of it was about 10-14", dry as a popcorn fart, and somewhat dirty. we ended up pointing the pressure sprayer at it for an hour (after we gotsed that running), then throwing a bunch in his jig.
blah blah blah long story short. the saw is quite a bit stronger. it's almost right there with my 46cc 346. has more torque than the 346 or as before, which i find funny as you usualy loose torque when going to a bigger carb. ??? maybe these are just way under carbed from the get go.
on a side note. my trusty old and very used 346 started to starve for fuel today. if you were cutting stuff up to 4"-5" it was fine. it was doing it when i was bucking some 10" poplar out back today. time for a looksee.
i'll try to get some vid of the 2800 in some of that same poplar tomorrow if it doesn't rain.
i'm so far quite happy with the outcome. :) gonna havta get me more of them bigger boots. 8)

That is the one mod I have not done yet on a saw.   A bigger carb.   I would sure like to try it on the last PP 295 that I modded.
Looking forward to the vid when you get it.
PP 505, 475, 445.

Still just thinking about.  ::)

I'm setting here with a extra 60cc p+c (would need modified to bolt on) a 335 54cc cyl only (bolt on) and a grey 3000.   3450 carb and intake set up.   
Really thinking of elongating the cyl 60cc off the 365 that was scored up from bad seals at one time, then cleaned up and reused.

Just dont know if it is worth the time or not for a future build. 49cc to 54cc or 60cc  sleeper saw.
