Diagnostic questions
Hi
Diagnostic questions:
When you say empty how do you know?
I've got electric fuel pumps on all three of my CMPs and when you turn them on you can hear the pumps fast click until the carb is full and line is pressurized. The pumps almost always run for several seconds up to 30 second if they have been parked for more than a few hours or over night or a week. They will also run if the truck was shut down hot fully hot even if it has sat for only 15-20 minutes.
Can you see fuel in the manifold?
If you think it is leaking internal down the throat have you tried running the engine with the engine cover off and the air cleaner removed. Shut the engine off pull the hand throttle out full or block the throttle open, try not to pump it more than once. Look down the throat with a flash light and see if you can see fuel running in and if there is a puddle of gas in the manifold. Let the truck sit for awhile and keep checking it.
If it was me and I was going leave it overnight I'd put a note on the ignition switch reminding myself that the throttle is blocked open. I hate it when I start the engine at full throttle.
Let us know what you find.
Cheers Phil
