    Default Another Carb Questions...BBC

    Have a 18ft Bahner with a big block chevy. Had it out a couple times this year and it idles great, It has a holley 750 double pumper, runs fine until the 4 barrels go to kick in and then it hesitates for a second and then it clears up and runs like a champ. The engine is mostly stock. I have a 600 holley vac sec carb i could put on it but it shure runs good when it clears up. It stumbles right when the boat needs the power the most, like when your just about to get a skier up. I runs great after that. Any ideas on what tuning issues i have or is it just to much carb?

    thanks alot

    Is this a problem that just happened,, used to run alright?

    Check to see if both accelerator pumps are squirting. Pull the flame arrestor or scoop or whatever and actuate the levers by hand without the engine running and note whether fuel is squirting from the nozzles.

    No. The boat is new to me and i took the wore out edelbrock off and put the holley on it. Ill check again but the squirters both look good. The double pumper is an aftermarket center without a choke tower and aftermarket bowls as well. It came or a drag car or mine and was running great on a roller 468 BBC.
