Slight Fuel Leak (above pump)

Chris and Pete - Thanks!!!!! - I found the cause. Somehow, (no clue how) but the accelerator pump adjustment had it to where it was constantly pressed down. I adjusted that to where there is a 15000" gap at idle (per Holly) between the arm and the lever (not sure if the terminaolgy is correct but you guys get it) and it idles great. I appreciate all the input and help. As always, you guys are the most knowledgeable out there. Thanks again....

Gary - Did it leave the black soot before you changed the fuel line?

These symptoms point to carb dripping internally. Could be coincidence that it got worse when you changed line.

You can look down carb throat when it is idling, you should not see any dripping.      Also, turn idle mixture screws in - they should kill the engine.

You can’t perform any meanful inspection of that screen in the adapter while it’s installed in the bowl. Since the fuel line will be off, just unthread the adapter and turn it over and inspect for blockages. With a functioning fuel filter in place, any blockage is likely to be pretty fine. Holding the piece up to light to see through it is helpful to judge whether it’s clear or not.

Gary,
Look inside the flare adaptor.

Well I did not see a screen at the carb at all. Is that going to be an issue? I did not notice a screen when I removed it either.

I did not, but I will go check. Is it on the carb or the line?

No Teflon tape or anything. The elbow did have some on it (red stuff).   Thanks for the MInfo on timing. I didn’t think so but thought I would ask.   Should I put some Teflon tape on the lines ends ?

*****UPDATE*****

I changed out the elbow from the fuel pump and fuel line. Leak fixed. HOWEVER, now it idles super rough and will stall. - Runs on top end great - I am going to check in the morning for the "stupid" stuff like maybe I bumped a hose lose or spark plug wire or something. I don't think I did, but I am a bit baffled.

Also, I wipe the boat down every time I pull it out and the rear of the boat had a black film - Burning too rich?

Could introducing something new into the fuel system ie. line impact the timing?

Anyway, any thoughts on this would be great. LIke I said, I will check for dumb stuff tomorrow...

Thanks everyone.

Gary,
I've used the Skidim fuel line too and like Gary said, it fit with minimum effort.

I am going to replace this part. Is this something I can get at an auto parts store, or does it have to be a marine retailer such as SKIDIM etc....

Thanks,
Gary

So I took the fuel line off and inspected it and the fitting. The fitting looks good, but the fuel line not so much... there is a definite deformation in the line right at the top of the nut.. I can't slide the flare nut past it.

I suggest disassembling the line off the adapter and unthreading the adapter from the pump. Clean both up. Look closely at the flare on the fuel line to make sure it's not split at the flare. If there's any residue on the flare and the adapter sealing surface, you can use a scotch brite pad to lightly remove it. Reassemble and see what happens. Double wrench the flare nut to the adapter.

Gary,
Is the fuel line the original steel?
