Resealed IP not pumping any fuel?

[ORCoaster]

The highest point in Michigan is Mount Arvon, at 1,979 feet above sea level.  Only 3% of the states population live in the Upper Penninsula.  So driving is pretty easy until you find that most folks really never learned the difference between a car, snowmobile or a boat.  They drive them all the same.

So w still noticing a slight lack of power. I am running it pretty advanced. My IP is dead nuts on the mark at tdc. If I want to move it a tooth off, which way ccw or cw should I move the sprocket by one tooth?

Getting any dark soot? If not, the full load might need another twist.

No coal rolling whatsoever.  I cant adjust my max fuel screw any more due to damaged threads from the OEM metal collar that was spot welded into it.

Got a spare IP that you can swap out the fuel screw?  Who would do that to an adjustable part?

Spot weld the accelerator too why you are at it.

I'd try to clean up them threads. A die might not do it, the weld will be hard... I'd use diamond files, it shouldn't take long.

Orcoaster  I like the way you think. Completely forgot about my spare IP. The thing is though, before I did the reseal if I had max fuel in as Mich as I do now it would roll coal like no tomorrow. I took the collar off after I put the newly sealed pump in.

My extra screw has a collar on it as well.

All fuel screws have some sort of limiter on them.  All of mine are just pressed tightly on.  You can see the mark.  But if you take the screw out and secure it well in a vise you can get the adjustment to move or even become a null thing.  I had one restrictor that I pinched 90 degrees to the mark and it more or less let go.  I could bottom out that screw if chose to.

Collars are aluminum are they not?  Softer than the screw it self so can't you just hold the collar and thread it by turning the screw inside it?  I can see if it was welded that wouldn't happen.  But surely someone is not happily running around CO with a MIG causing all this havic?

all of mine have been steel resistance welded to the screw.  pry the seam open a tiny bit, and drill or grind the weld, instant adjustable stopper.

M8x1.00  I've run a tap over many of them.

I took the screw out and the issue is that the collar that holds the o-ring in place is the thing that is preventing the screw from being threaded in more. Not the threads themselves.

So the lever is pushed in as far as it can go.

If that is the case than you STILL have the accelerator lever to shaft alignment incorrect.  One click the opposite of what I described before.  When the revs were hanging before, had you run out of idle adjustment?  Was the lever rotated all the way back so that it was hitting the case at idle?
