ended up leaving the the conrod/piston in flanno, didn't want to damage it.
Thanks for all the info guys, motor in buggy now to be run-in tonight.
And yeah as some noticed at the nats' i was running a ninja. Thought i'd try the go engine now so i don't feel like the dark horse in the hobbyzone/massivemods team plus i wanna try one anyway after seeing the one in deano's car, should be good. If its all good ill get another one for the truggy.
Thanks again guys.
