Here are the symptoms. 2.0 engine running duel Webber’s no chokes. Tried to go to C&C this morning a really cold 45 would not start so I sprayed a little starting fluid into carbs it fired a little because I really want my coffee. Sprayed a little more it fired up and screamed to 5-6K Rpm. Had to turn the key off. Let is sit a little while fired it up again and again screaming to 5-6K. Throttles not stuck. Started again and it idled nicely. Without touching the gas pedal it screams again to 6K. My only thoughts are the new fuel pump that I installed back in July which ran great all summer may be the cause. Any other suggestions. Help I need to get my coffee.

Check the butterflies first. Just look to see if they are seating. No need to disassemble anything but the air cleaner if you need visuals rather than lever position. While watching the butterfly have someone start the car.
If that all looks fine, I would get a buddy to turn the car over while you physically block off most air entering the carbs with your palms. See if you can modulate the rpms. If not you have the mother of all vacuum leaks. If you can, and the butterflies are closed, have your buddy spray carb cleaner everywhere till you find the vacuum leak. I would suspect a large hose leak (like pcv size on a FI motor) but I am not sure what you have on yours. I suspect one side will be enough to make it race under no load. Do you have a pcv? |
