| Post subject: | fuel smell at open throttle |
Hey guys After my exhaust swap, I smell fuel after a while of OT (not WOT) let's say when hitting hard on the gas at 50 and speeding up to 75 - 80 (I'm not flooring it, not even near) But I don't know if I should blame that on my new ex 'cuz I did some tune up along with the ex replacement. I changed spark plugs, I cleaned the carb (ain't leaking) and I installed a new distributor.  I'll appreciate any comment on this matter. Juan. |

You smell fuel with the engine running and the car moving down the road? What carb are you working with? Are there any exhaust system leaks/ How does the tailpipe exit the rear of the car, straight back or off to the side? DD |

Hey Doc No ex leaks, and the pipes are straight back (one on each side) I'm working with a single barrel holley, but not the 1920. It's similar, with bigger venturi, bigger throat, more CFM and more bowl capacity. It says holley 1922, but I think that's a local version of the 1920. Today I lowered the bowl level (regulated the float) and seems to be better... maybe it was just too "fat" ?

Could be your float bowl vent isn't closing when you open the throttle. Its only supposed to be open at idle and when the engine is shut off. |

http://www.potentialtech.com/pmoran/vent.jpg  I don't know why, but my email doesn't seem to work half the time. I didn't even get a bounce notice? That why I'm posting as a guest.

Thanks! but mine hasn't that vent. It's a holley licensed carb manufactured in Argentina, then modifyed to get 300 CFM plus outta it. It's a manufacturer's modification, not custom. Maybe I can post some pix... That explains why I made a fool outta myself with the question.
