It doesn't sound like its getting enough fuel to the carb.

I would try to tap in a fuel pressure gauge & find out what it actually has for pressure.... you will need to take it for a ride down the backroads & get it to stumble & see what bthe gauges says.


had a friend put some RTV silicone sealer around his fuel cells filler neck & the gas dissolved it & it ended up getting sucked into the fuel line. It had a very similar problem & had only enough fuel pressure to run low RPMs.


what kinda carb are you running?

I had the ball fall out of the rollover valve and get sucked into the fuel line. After the engine was shut off it would roll out and back into the cell...then it might run a dozen laps before it found it's way back into the line...drove me nutzzzzzz!
I keep that dang ball on the dash of my truck.

Just a quick thought.....i know you said you've checked the accelerator pump.....how bout the ball underneath the plunger?? If it isnt sealing good enough you're only gettin minimal fuel shot upon WOT....its just a thought....good luck!
