Thanks Randy. And yes, you was right on all accounts. That's what I was asking.
I'm pretty sure the reeds have been upgraded, just by the stickers that are on the buggy, when I got it. So I'll see what's in there.
Meant to bring this up in last post and forgot.
Best way for leak down test. Best to seal of exhaust port, intake port, (with the boot). Leave spark plug in, and add the pressure from the pulse tube? Is that correct? And piston need to be all the way down. Correct? Or do I test it twice, one piston all way up, and one all the way down?
Thanks
I use a freeze plug in both the intake boot and the exhaust flange and yes, I use the pulse tube as the spot to pressurize the Engine. As far as the piston being up or down, theoretically it should be at bottom dead center but I have found that it doesn't make a difference at least on a fresh top end bore because the rings haven't seated yet. The pressure within the entire
Engine will slowly equalize with the piston at any position.
