1985 yfm 80
Hello everyone I just bought a 1985 moto 4 80 cc atv for my son. It has good compression and good spark when the plug is outside the cylinder grounded to the case. When I spray starting fluid in the cylinder it will not fire at all. I checked the timing and both the cam sprocket mark and the fly wheel mark are correct. This makes no sense to me. Can anybody help? Thank you for your time

Does make a difference between the two engines.. Check that the crank case vent is open. Dirt Cheap Yamaha, Honda, Arctic Cat & Polaris OEM Parts & Accessories – Cycle Parts Warehouse
