I presently have my accel pump (GPR1200) disabled by turning the screw on the actuator arm all the way in. This lifts the roller off the cam on the #3 carb. I've been having trouble with the throttle sticking since it did this. I think the arm pushing on the cam would help close the throttle since the arm in spring-loaded.

Would running the screw out to fully compress the plunger all the time also work to disable the pump? I'm not sure this would be good for the diaphragm. Any other methods I could try without removing the carbs again?

Britam,

Something is binding your carbs OR cable. The accel pump was just a band-aid. When you disabled it, you exposed a symptom of a broken or near broken setup.

This can be very, very dangerous... Think 1000lb 65mph missle.

I would start by disconnecting the throttle cable and determining where the problem really lies. After that you may need to remove the carbs, and find the binding.

I just removed the cam and replaced it with small washer. That way i can still use the pump as a primer.

I you have something binding, you need to find it ASAP.

Wow, that was a safety hot button. [Smile] Based on other posts, I think I know where the problem is. I have a 2000 without the plastic spacer between the carbs and block. From what I read the heat from the engine can damage the shafts or seals. My understanding is that there is no fix other than new carbs. The term stick may also be alittle harsh. It's just a little slow getting back to idle, maybe a couple hundred rpm. I'm sure it's in the carbs, since I can watch the cable return all the way and the wheel slows for the last couple of degrees. None of the other posts mentioned the carbs sticking open at any sort of major throttle. If anyone has experienced otherwise please let me know. Otherwise, I'm just looking for a way to give it a little nudge at the bottom.
