MODELS CARB QUESTION.

1981 Mitsubishi Other

1981 Other Mitsubishi Models

Hi, I know my carb pretty well. I've rebuilt it many times including just recently but i'm not sure what to make of this.

On the accel pedal, I press to accel but theres a flat spot in accel. The engine hesitates for a moment. So I checked the accel pump. Works great, good strong jet of fuel BUT only on the release stroke of the throttle. For example, I open the throttle, when it closes I get the good jet of fuel. I've looked and looked at it but can't figure out why its doing this. Any ideas?

Thanks,

mike

Hi mj007nz, Welcome to to carpros and TY for the donation

Sounds like the Acc pump cup is set backwards investigate
