ya see what this thread did to me......Now I'm gonna take my 028 apart again and do some more porting! I secretly love it!
Great thread! What chain do you recommend with this saw?
When checking squish on a stock 260 pro, can you go through the spark plug hole or exhaust? Or do you have to remove the cylinder to get the correct reading?
The dome piston won' affect the reading doing it that way? Looks like a tapered smash for about a 1/2" then towards the very end about the last 1/8" it gets smaller, is that the squish band to be measured? Long time member but new to this.
Hi there Randy
Would it be possible to turn a tapper from the outer edge of the piston inwards,so to have no step which would help with flow.
Yes it would. I doubt it would yield as much compression though.
I've evolved to cutting the squish band on these saws now. With the right shape on a cutter the step can be cut out nicely.
Are you just turning a "straight taper" on the squish band up to the combustion chamber ?? What angle , 2* ??
What carb work are you doing on the WT194 other than a polish & thinning ? Venturi boring ? re-jet ??
