That Deere is a pretty hot saw! :msp_w00t:

But I'll go easy on him. ;)

Levi says you'd better bring your "A" game...
He's feeling good about his chances...
Liking his chain right now... But don't worry, we got plenty of time to mess it up between now and then...
 
Must have been the way the chain was grabbing made it look slow. You are right. :(:(

Stumpy did you change any thing that you know of.

I know, it felt slower too. The 345 has a milder feel to it when running it and doesn't turn as many rpms outa the wood as the 346. So far I've got it set @ 13,800 no load, but it pulls around 10,500 in the wood. I was feelin lazy today & didn't spend much time fine tuning it.

The only big difference between the 345 & the 346 is the case and the aftermarket cyl. The only porting change was on the intake. the 346 had a few more degrees of duration, but I widened the intake more on the 345 so there should have been much change in volume pulled into the case. Otherwise the size & shape of the ports was as close to the same as one could get by going off of memory & pics of the 346 jug. I wish I would have measured the case volume with some fluid on the 346 & compared it to the 345. Just off the top of my head & by looking at them there wasn't much of a difference. I wonder if the feel of the saw has something to do with the plastic case & plastic handle absorbing more of the vibrations & harmonics than the mag case & aluminum handle of the 346.

Overall I'm pretty satisfied with the way it turned out.
 
The chain can make all the difference in the world, which you made more aggressive. The 346 definately sounds stronger, holding more RPMs in the cut.

I know, I'm still wishing I woulda left the chain alone so the comparison woulda been more even. Actually by the tach they were both holding around the same rpms, hence one of or possibly the reason the 345 was a tad faster since it was taking a lil more bite.
 
Awesome thread, i say. Kind of "common mans hot rod saw" thing going on.

I had to dive in to my pile of junk saws, and i did find a oe346xp top end, as well as several plastic cases. BUT, i have to ask, about that adapter plate .....whats the part number for it, if there is any ?
 
It'd be interesting to see if there's a difference in the volume of the mixing area of the crankcases between the two saws. That would make a measurable difference.

If stump were to have just replaced the jug and put it on a 345 case with less capacity than a 346 "assuming" any way, the rpm's would be a bit lower with a slight rise in torque... Provided there was enough case capacity to feed the larger jug...
Stump gave it more capacity than it had stock, but how much was that?
The port timing was changed also, so this is all speculation... And I'm taking a break, and standing here in the shade... I think the heat has cooked my brain... :dizzy:
