flooding out, may need to adjust float levels.
or, fuel pump losing suction from gas tank? Do any mods or work on the car lately? If happening under full throttle, may have clogged fuel line/filter. |

If that's a Holley 750 dp w/center hung floats,yes that's not a good carb for off roading,get one of the side hung carbs for trucks or better yet,fuel injection.

Sounds like it flooded out by having to floor it to start it again. Fuel sloshed up through the vents, maybe. Off road carbs have that U shaped bowl vent that runs up above the carb. Lots of hi-po parts available for those carbs. google it, this is the first one I found.....http://www.greatlakes4x4.com/showthread.php?t=66130 This is a great site for off road.

Found this on Web: "Once when we were wheeling this guy with a Holley in his pickup couldn't get back up the hill - it was loose and rough and his engine kept flooding out. I took a piece of surgical rubber from a wrist-brace type slingshot and ran it from vent to vent with a small hole in the top, just cleared the top of the air cleaner. Worked like a charm, no more flooding. I have no idea how long the tubing lasted, but I do know that trick works. That is my only experience with Holley carburetors."

I agree with the hose from vent to vent with a small hole at the top. I have one of holleys truck avenger carbs and it has the vents hooked together with a pipe and a few holes across the top of the pipe for the reason of fuel sloshing out the vents.

Oh one other thing. I think there are such things as "spring loaded needle and seats as well to help when bouncing around.

P.S. I already told you in pm, about the vent tube trick... that will settle down a lot of your issues. |

vent
yup when i picked out the carb i agree rampage, off road everyone thinks slow rock crawling where spinning tires is not what you want, they want slow throttle, easy into it to crawl, i want tires spinning rpms screamin wheel speed to get goin starting in a mud hole! not that i wouldnt like to try crawlin but rocks are not very abundant up here! trees and fields.... lol
