Priming fuel pump causes car to catch on fire

If the carburetor is dry, pouring gasoline into the bowl vent will allow the carburetor to function normally. A syringe works very well but a turkey baster with a short rubber hose will also do the trick. If it’s just a cold start problem pouring a few spoons full of fuel into the dimple of the breather lid with the hold down nut loosened a few turns often gets things going. I have had an engine backfire and the carburetor melt before an extinguisher was located and used. After that mess was cleaned up there were CO2 extinguishers on every pillar and doorway and work station in the shop.
