just to eliminate the obvious, check the fuel vent, and check the primer bulb. then go ahead and run a compresion test and spark check to make sure you don't have anything serious going on, if that checks out ok, then go ahead and rebuild the carbs and fuel pump, clean out the fuel system, even if its not the main problem, its probably due

Apparrently I have an issue with my speed limiting overheating warning(S.L.O.W.) that is causing my RPMs to drop so low. I am not sure why it is activated though. My pump is working fine and the thermostats are working. I guess I will have to grabe a manual tommorow and see how to correct or bypass the problem.

Is the alarm going off? What Year? I have a manual sitting right next to my computer, or I'm sure SKOOLS can site the JOHNNY-RUDE book for us if needs be. Really need to know what you have to help you figure it out here. There is a chance that the warning horn has gone out and is causing your problem, or the diode(depending on year and model) could be blown and shorting the S.L.O.W. sytem to stay in start up self test mode which would limit it to 2500.
