 Can anyone suggest a forum or website where I could learn more about these engines.  All I have done to them is clean them up externally, I removed the heads and measured the cylinders and put some klotz in them before I turned the crank to move the pistons.  The cylinders all look pretty good and the ports are all unmodified.
I am wondering why the ultralight folks all turn the cylinder heads one bolt over, I was told it had to do with cooling and the movement of air because of prop blast, but I dont know.  There are no mods at all that I can see.   They all use recoil starters and clutches with belt drive.
Is it safe to try to start these?   The bottom ends are pretty well sealed do I really have to open them to be sure the lower end is lubricated enough to start? 

Compression seems no where near that of Macs. 

Any comments/advice?   Thx...
