I used to have an XTM 24.7, now I'm running a Mach .26. Both motors had two headgaskets, has anyone tried running just the thinner gasket with 20%? That should bring up compression a bit, maybe run a cooler plug so it don't detonate?
I haven't, but if it works out for you, I definetaley try it out. How much more compression is there? I remember you telling me something about the pullstart being alot harder to pull at this past sunday.
I've never met or talked to you before bub.... hope to see you soon though

Sorry, I should have used the quote button. I was replying to jack's post.

I don't know, I figured higher compression=more prone to detonation. I ran the motor last sat. and it seemed to run fine on the thinner gasket. It was a lot harder to pull the pullstart, though- it felt like I was about to rip the pullstart off the backplate. Don't know if it actually increased power, the mill is in a different car.
