sounds like a sticking control plunger in the fuel distributor - not returning all the way to idle rest

I have yet to check my Air Flow Meter plate.But if that were true, then a zero-position of the plate on the venturi that is too low will cause fuel to leak.

Anyone can confirm if this is correct?

If so, then the zero (and basic) position of the AFM plate is crucial in getting the right mixture.

UKEvo had advised me to do this earlier but I thought it only had bearing on the idle.Never looked at it from the plunger point of view.

But I hope someone can help me confirm this.

Also, if the plate is set too high/low, what is a good way for correction?

I may be wrong but I read somewhere that if it's too high, you tap it down (somewhere) and if it's too low, you can pull lightly on the bolt at the top of the plate.

Anyone?
