I never expect that ez start would crank the motor that hard.

Its a combo of spring power and inertia... doesnt supprise me one bit... add in a hamfisted operator yanking it like a large saw and twists will happen....

Nice, congrats!!!

This is the first startup tank after warming up.... for having about .050 squish to minimize (got it down to about .010") free port at tdc, it runs pretty snotty..... would love to have a way to get the squish AND the freeport down..... could be a real beast then.....timing is pretty close to stock, as i just kinda freehanded it, intake was lowered a hair, exhaust was raised and widened a hair, raised mostly to just even out the lopsided port from the factory LOL, lower transfers opened up and smoothed into the uppers, since there was a nasty bulge in both ports that restricted the flow of the casting, and uppers were untouched since i dont have a right angle head for the flex shaft nor do i have the cahones to take a grinder to the uppers yet.... my woods port saws run pretty dang good "in my opinion"

Thanks to @StihlEchoingHusky this saw lives again... joint effort on the massaging of the cylinder thanks to modern tech being able to send pics and vids back and forth... ms460 with hyway big bore 54mm with a pop up piston... compression reading is before first run, on a lightly oiled cylinder and piston...

It’s got 10 thousandths squish only? Seems a bit tight compared to what lots of guys like at 18-20 on bigger saws but hopefully she runs a long time.

Could you put 066 piston in it? According to meteor website. Squish would be a little higher and skirt would be longer might have to trim skirts down to make it work

I am thinking no, as i already had to trim the intake side skirt a few thou to clear the case....was hitting at bdc.... i could have trimmed the case, but didnt want to have to flush the bearings again....LOL
