Re: ’62 5.5 Fisherman won’t idle

quote amuller:

Finally got this running in a barrel and all seems well except it won’t idle. Will run steadily in the Start position but no slower. Seems to come closest with the idle mixture needle fully closed. Thought I went through the carb carefully but I must have missed something.

Any suggestions? Would a clogged crankcase drain cause this?

Well, a clogged crankcase drain could surely cause this engine not to idle…
You mention the best it runs is with the idle needle valve just about closed…How about a leaky fuel pump? Please don’t rip into the fuel pump to test my theory, simply unplug the fuel line and let it run a bit until the fuel is out of the pump/lines…If the engine seems to clean up before it stalls, we can talk more about the pump…
