OK so you HAVE eliminated your O-ring issue?
You have both the reed cage O-ring AND the Insulator (black piece) O-ring? And your 100% sure it's not leaking?
Remove the top motor plastic. Any doubts on head/base gasket leakage and replace both.

I have been working on this quad for a buddy. When he brought it over it didnt run. Well removed the carb and cleaned well...then changed the o-rings and changed the spark plug. After all that i put it back together and hit the starter. It started up after cranking a while and ran for about 5 min. and then bogged and died. And wouldnt restart.I cranked for a while and it kinda speeds up like it gonna start but just wont. I let it set for awhile and bam it started agian..and then the same thing, after about 5 min. of running it just boggs and dies.
I did a compression check and got 125, so im ok there.
But i did notice a lot of oil on top of head. I cleaned it off and when i ran it till it died i noticed that all that oil was back. Could i have a blown head gasket?
