I've recently noticed that my engine bogs and some times even stall when I move from a dead stop typically the motor either stalls or jerks the car. This always happens as I begin to press on the gas when I'm letting out the clutch at around 900-1300 rpm. I've adjusted my idle, timing, air/fuel screw, and still nothing. This aside the car starts and runs great. I figured out that if you rev the engine a little higher then normal and keep pedal in the same position as I let out the clutch I can get a smooth start, but it can't be good for the clutch. Any Ideas?

 

It sounds like you Accel pump is out in your carb. This is in charge of shooting the extra gas needed to get the car going. So it might be time for a rebuild, or I think you can just but the accel pump diaphram from mazdatrix.

It is the square thing in the picture.
