MC2100 is great! Still need help though...
Just got done swapping my carter for a motorcraft 2100. Very easy... It took less than 1 hour to get her running. Check out my throttle bracket in my gallery...that took a few hours of trial and error.
Here's the problem I'm having:
There is a spot during the acceleration curve, where if you hold the throttle just right, it seems to choke out the carb. This happens going from idle(650-700rpm) and ends just over 1000rpm. In 3rd gear around 1000rpm there is a slight surging.There is usually a lope in the idle when this happens as well.
Furl pump is pretty new I replaced fuel filter, the cap/rotor are also pretty new. Don't think there are any vacuum leaks at the base... Timing set around 8* or 9*...
I replaced the plugs with some cleaner, but still used, plugs(my carter had the old plugs fouled pretty good). The rig ran really well for a couple of hours today, but for some reason is now back to having a lope in the idle, and pushing the throttle just right will stall it out.
Accelerator pump? When the engine is off, I pump the throttle, gas sprays out of both jets.
I didn't rebuild the carb...It came off a 74 bronco that was running well...It looks to have been rebuilt recently.
