Not sure on the cylinder name will have to look around on it (it was in a Farmertec box but that doesn't mean anything). I did my squish opposite sides one through spark plug one through decompression valve (above intake / exhaust ports) though to be thorough I guess I could gone with the 4 way...
I just did a crude (no plug instead of decomp valve, tester threads were a bit long so I had to use plumbing tape) compression test and got around 130psi. Seems a touch low no? Not sure if I can give it a strong enough yank this morning.
I have only run the saw/rings in for about 5 mins max & NOT at all close to max RPM (carb needs adjustment to make sure everything is correct and the Chinese wrist pin / bearings need to be replaced with OEM) so I wonder if it's effecting it?
This is my second saw ever, the previous one is a Mac 3216 I resurrected, but I have done a ton of dirt bikes so the engine thing is not that foreign.
)? I am leaning towards eBay?
and cylinder number two has no name but both have the same issue with the nisi not going all the way across the squish band and in order to get a good squish that nisi on top needs to be mild down my meteor cylinder has nisi all the way across the squish band an it's the opposite it has to much on the inner eg of the squish band but it's doable so be careful take it from someone who fixes and port's saw's for fun you can really muster up if you're not paying attention. All us guys that port saws have been there and done that and sometimes wish that we didn't.
