When I do get it started and can rev it, as soon as I remove the glow plug igniter it cuts off. I heat the head with a blow dryer and wrap the head with foil to get the temps up.
HALP!!
Check the pressure feed nipple on the exhaust pipe. I had pipe once that had a blockage in there. No pressure was getting to the tank. Poke a piece of wire down the nipple or blow through it and make sure it is clear.
If it's blocked you will be running super lean and engine will start but won't keep running more than a few seconds.
Sometimes the fuel will squirt out of the carb throat when starting. Don't run your engine without the air filter for long though. Any dirt or dust down the carb throat is a recipe for disaster
