Jeep CJ 258 Acceleration Issues. Please Help!
 

Hey guys, I have an 84 CJ7 w/ 258 Carter BBD and T-4. It has the TFI
upgrade and the Nutter bypass. The motor runs very well at idle and at
constant rpm, but when I accelerate it bogs / stalls until the rpms
finally catch up w/ it then it runs great. I can put the pedal to the
floor (In any gear) and slowly let the pedal back up to about 1/2 and
the motor seems to catch back up.

I was wondering what tests I can perform to see if my problem lies
within the fuel or the spark? I was trying to avoid just replacing
parts until I get the right one. I have the timing set at 9 degrees
BTDC.

Any help would be greatly appreciated.

Also I failed to mention that I had the carb rebuilt, and it still
happened, and then I went out and bought a brand new carb, and it still
happened.

Then the accelerator pump doesn't work in either.

That is my guess. The accelerator pump gives the carb a little extra squirt
of gas when you accelerate quickly. When the engine is turned off you can
hear / see it squirt as you pump the pedal. It is also adjustable if you
need to have it provide more fuel. Another idea is fuel filter or fuel
pump.
