Didn’t do a timing advance yet. Just widened and enlarged the exhaust port a hair. That bog in the end was the EL. Ill have to make some test cuts with it soon. And 562XP 1 video was the 5 screw cases with same mods as the one I just posted. Not gonna go further with the belt sanded piston.

As I said earlier, extended piss revving of the autotune saws causes their tuning to get out of whack. Also long partial throttle running will do the same.

Make some decent cuts and it will start to behave better.

@srcarr52 I saw that 562 ignition advance study video of yours and I gotta say that 562 is SNOTTY.

Yeah. I sold off all my 562’s when the 572 came out. I’m starting to miss them an bit. There is one I ported slinging a 32” skip killing pines on the west coast. Mean little machines they are when ported.

The 372 has a 51.4mm top end and was tuned a little fat for this vid. I put a couple more tanks through the 562 and its starting to act different... in a good way. The 562 and 372 chains are just about on their last sharpen and the 2159 chain was brand new but I could have taken the rakers down a little bit. It was’t feeding as good as the other two. The 372 is slightly aggressive as well as the 562. Really happy with them all.

Thanks Jeff and sorry about that annoying glare. Wans’t usin muh brain . Yesterday I experimented with a 9 pin and 20” with a semi aggressive chain on the 372... it runs WAY better than what I expected. I thought it was going to bog it down bad.. I was wrong. Ill have a vid posted in a little bit
