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.

Look for massive vacuum leak, bad gaskets, misadjusted linkages, or air bypass screws that are too far open.
Engine shouldn't be able to sustain 5000-6000 rpm on closed throttle plates - simply can't pull that sort of air volume past a fully closed throttle plates. Not ruling out too much fuel pressure but even if it is getting too much gasoline from overflowing float bowl, it still needs air to burn it. |
