Sure, if it has been sitting. Get a dish detergent plastic bottle and drill the lid out to fit a small diameter clear hose snugly. fill it half way with 50/50 premix gas &
oil. Stick the hose in the vent hole of the carb. Do not over fill. I put a 20 thousandth carb jet in the end of the hose. Soon as I see gas's coming out the vent around the hose. I stop, then start the engine. Let it run un tell the smoke clears. There is also a marine product to winterize your boat that is sprayed down the carb at the final shut down that will solve the problem of condensation and rust in the cylinder and intake.
