A new to me 1986 Prostar. Cold starting absolutely no issues. Hot start within 1 minute of shut down, say to switch out skiers, no problems. After waiting a bit, say to drink a cold one and float around a bit, the smell of gas fumes becomes prominent. Blower on, open the engine cover to vent fumes, then the engine will not start (cranks fine) - taking it to near WOT and cranking will get it to fire though.

Thoughts, suggestions on trouble shooting?

Carb floats sticking?

You probably have fuel coming out through your venturis into the carb. Shut it down hot and before trying to restart when you can smell the gas fumes, take a look down the bore of the carb to see if there is fuel present. Check to make sure the choke is wide open too.

Most likely you are in need of a carb overhaul.
