Hey guys.
Just building a spare motor out of parts I have laying around. I have a CY 29CC bottom end, it's a 2 bolt, and I have a 4 bolt fuelie 30.5cc piston/ring and head. After putting it all together, the gasket seals, the piston moves inside freely and there's lots of compression. Do I need to check for anything else? Does it matter how much clearance is between the spark plug and the piston head? There's no contact between them. The 4 bolt head kit I have is listed to work with 29cc and 30.5cc motors. I was surprised it all lined up properly with the exception of the 2 bolts that aren't being used on the head. The gasket seals perfectly around the head. Just want to make sure everything is ok before I attempt to fire it up. The CY's 2-bolt head replacement is just way too much money and isn't worth it imo, so if this doesn't work I'm just going to toss the motor.
thanks,
Bry
