Default G14 With a Low RPM miss, spit, sputter

A few weeks back I traded for a g14 gasser and have been currently been restoring it to give to my Dad for a yard and farm ride. I've got a post over in the Lifted Section but thought I'd post here also to get more coverage.

I will explain this the best way I know. Hard to crank, sometimes have to run with choke partially on. Running at a slow pace it sputters. Throttle response is sluggish.

I think of my self as of mechanical mind and body on this. At low rpms it spits and sputters. Pull choke a little and it picks up. I never thought much about it, cause I'd cross that hill when I get there. I'm thinking something simple, but every simple thing I've thrown that way proves as a failure.

Things I've done:
*cleaned carb
*new fuel filter
*cleaned tank
*cleaned carb again
*adjusted the valves

Results:
*seems to run best at richest point of air mix screw adjustment. (runs best with screw riding in my pocket)
*at one point runs best with air box off carb(I had an K&N and an adapter that I ran for a while,... runs best)
*If you run with choke 1/8th out runs ok, but not best.

Things I'm thinking about trying:
*New fuel pump(don't look like its pumping enough to me and spark plug is chalk white)
*complete tune-up(filters, spark plugs)
*check signal fluid

Cart has set up for a while before I owned it. I think it was a greens keeper cart at a local golf course.

Chalk white means leave I'd bet the carb has a plugged jet or passage way I know you said you cleaned it but try it again and us a little compressed air usually if fuel pump is weak it will fill the bowl and lower rpms then speed up and run good until bowl runs out of fuel

Will try it, gladly.

I was thinking that the fuel pump is not pumping enough.

What if the governor is adjusted too high? Looks like some drunk mad man late one Saturday night may have done just that. (been reading in the stickies)

Amateurish question but are G14s 4 strokes?

Yeah, I am with Spicy. Fuel pump is probably bad.

Come to think of it. Every time I've taken the bowl off it didn't have a lot of fuel in it. I will try a plug and pump. But I won't change them at the same time to see which one it is. I do it all the time change five things and don't know which one fixed the problem.

Problem fixed.

After hours of searching, 4 carb cleanings, new fuel pump, new fuel filter, new air filter, new spark plug, valve adjustment, one fuel tank cleaning, and lost count on the Coors Light, it runs like a top. And none of the before mentioned was the culprit. What I found was that the previous owner had turned the idle screw in as far as it could go. So once the cart started the butter-fly was open already giving it fuel and flooding it at low rpms. Backed off of the screw and it runs like it should. I'm glad cause I was about to pull the trigger on a new carburetor. (which if you think about it, would have fixed the problem)

Thanks everyone. Hope this helps someone else with same problem. I want to say this is why the cart was set up for so long and why I got it so cheap.

Yeah, sometimes it's the little things.

Sanity check for me, if that idle screw was all the way in that would have restricted fuel, no? You sure you were flooding and not running lean? Are those carbs different in some way?
