Oh, your going to get me in trouble this time.
Here's an old Diesel Mech's way... so be CAREFUL.
The Carb's opposite the Distr. & Spark plugs, so when the engine is COLD and running take a can a starting fuild and lightly blast around the base of the Carb. and intake. If the engine speeds up.. you fould it.
Be D&^%%^D Careful.
