How much did ya take out of the squish band?

 

[tlandrum]

so brad what are you planning doing about the low cmpression?

 

[blsnelling]

.035" with a squish of .020". I've not had it in wood yet. Throttle response is 346 like.

Might have to go with a dished piston

the 385xp i just built had 200 on a new cylinder cold and dry. i may end up putting a gasket back in it after alittle more run time. it runs pretty good as is but thats a bit much for my taste in a work saw.

Cant wait to see her in some wood Brad. You just know she's really gonna rip.:msp_thumbup:

I would agree with that. I was hoping for 185-190, so I'm very pleased. This saw has had very little fuel put through it, so it might gain a couple more PSI. We cut the base so that I could run a factory gasket.

I'd love to have a pipe built for it. But, I'm not sure I have enough blowdown for a pipe. It's my understanding that a pipe likes lots of blowdown.

 

[blsnelling]

I'm headed out now to see how she does. Gonna be a cold one! Windchill temp is only 4°F.
