3000 rpms change with angle

3000 158 gasser, almost 2 hrs on break-in (complete motor rebuild) holley carb, power piston freed-cleaned-polished & lubed. Run it uphill or leaning and the rpms go up regardless of throttle position. Max they climb to is 2000. Does the same when running out of fuel. Is my float level off? Set it to the 7/8 hillside spec.
Any ideas?

Just to post a followup, I was getting a miss that would come and go if you played with the dist cap or wires, plugs were sooty.

I checked point gap and found I'd set it at .016" just got done doing the 9N and had that on my mind.

Re-set it to .025" and it's running better.
Might still need the carb done but it's smoothing out.

Thanks Bill, I hadn't thought to check volume - just knew it was pumping.
I don't have the air filter piping clamped down, just slid together right now, hadn't thought it'd make a difference but I'll tighten it down.

I think I may have to re-adjust the carb to the non-hill settings too.

I,m gonna guess too high. did you check the fuel pump to see if its actual pumping correct volume and pressure? That can throw a wrench in the works.. Is the tank almost empty? a leaking fuel line sucking air? or is there a loose connection at the manifold or carb causing an air leak when tractor at certain angle. otherwise go back to the bowl... too low or too high. I'm going with too high. However could be loose main jet or other anomaly, worn throttle shaft, butterfly about to come off shaft and few other things I have seen.

On cars,, I would jump up and down on the bumper.. a high float setting would make it run rough for a couple of seconds...

running the fuel pump, lines are correctly routed.

The float is brass and no leaks (when I checked it 2 months ago), I did set the level for the "hillside" setting rather than the 13/32" (or whatever the other setting is - don't have it handy right now).

So you think too much fuel is causing this? I was thinking it was running lean - that's what it would do when I'd run out of gas running the pony tank (lawnmower gastank that held about 3 cups of fuel - got me approx 8 min of run time).

is the fuel pump working or is it gravity fed???? or float set wrong. If float set too high or low it will also do this.

Same problem years back. It's the float, or the needle and seat are not seating.

Today's Featured Article - Tractor Traction - by Chris Pratt. Our first bout with traction problems came when cultivatin with our Massey-Harris Pony. Up till then, this tractor had been running a corn grinder and pulling a trailer. It had new unfilled rear tires and no wheel weights. The garden was already sprouting when we hooked up the mid-mount shovel cultivators to the Pony. The seed bed was soft enough that the rear end would spin and slowly work its way to the downhill side of the gardens slight incline. From this, we learned our lesson sinc ... [Read Article]
