Earlier I had incorrectly post a carb thread. Here is the new version

The WEBER carbs on my 454's both drain after sitting for a few days and the long cranking start up is necessary. There are many threads regarding this issue but I cannot find a firm solution. Anyone have a suggestion other than replacing them ?

What I use to do with my qjets engines is crank the starter on one engine 5-10seconds with no pumping of the throttle. Then do the same to the other engine. Then come back to the first engine give it one pump and it would fire right up. Then go back to the second and it would do the same.

The information i posted was for a Weber , i hope you read it before deleting .

Sorry once I realized I screwed up I also suffered further brain fade and deleted what was posted without reading. I think it has to do with the long winter !

I've been doing this for a couple years now. The cranking usually closer to 15 sec. followed by giving some throttle and maybe the engine fires, maybe not followed by more cranking. I do avoid playing around with the throttle during the process until after prolonged cranking. Starting to get concerned about starter life. Once it fires it's good for any other starts that day or the next 1 or 2 days.

Electric fuel pumps cure this condition as they provide fuel to the bowls instantaneously . I purchased mine from Teague with their pressure spring , eliminates the need for a pressure regulator . Twelve years of use and 0 problems . Of course now i probably just forked myself by saying that . Holly black pump-Teague pressure spring . Mount as low as possible . Hope this gives you an alternative idea . Sam

Thanks Sam.

Electric fuel pumps will mask the issue which is in the carbs. It is a common problem on older Webber carbs. The bowls leak out the fuel.
IMO, you are better off to have the carbs fixed/rebuilt or replace them with some Marine Edelbrock carbs which are basically the same as the Webbers.

Aside replacing carbs or adding an elec. pump, you can take a squirt bottle w/ fuel in it and squirt fuel down the primary vent bowl tube to fill up bowl before you start it. Still a pain in the ass but cheaper than the alternatives.

He did say he has the problem after the boat has sat for some time . This leads me to believe it's more of an evaporating fuel problem . After it has been fired and run it will restart just fine . Am i correct Ed ?
