On this carb the manual shows the float level is adjusted when the carb is held sideways,float arm tab barely touching the needle. Usually sets at 13mm (.051) from carb base to bottom of float, BUT if it was set correctly,when held upside down the bottom of the float usually will be parallel with the carb body.

This is a special metric o-ring.. Try a good hardware store like Ace,etc to see if they can help. If the float arm and float pin are wobbly,could be source of the problems. Most people over look this because they don't come in carb kits. Must be ordered from a dealer or cheaper online. If you do need these two items just order the new o-ring with them.

Retrace your steps on the carb rebuild you did along with making sure fuel flow is good from the pump,if you're sure the cam is timed ok,valve clearance ok,cam detent spring hasn't slipped from the lever . If it was spitting before the cam install and still doing it,then there's something somewhere you've over looked.

We've been talking about the cam,valves,etc,but one thing you can try is unplugging the black wire from the reverse limiter module and see if this solves the problem on spitting back. They can short out and cause limiting in forward range.Item #30 Dirt Cheap Yamaha, Honda, Arctic Cat & Polaris OEM Parts & Accessories – Cycle Parts Warehouse
