I got it up and running, but I can't get it to stay running smooth in full throttle, low throttle and the start position run fine, could run better I'm sure, but anything just passed the start position on the the throttle and it starts to chug and run like crap!

I need help, I don't know much about it, I have found a new carb kit that I will likely be installing, but I'm not positive that its the carb or the air to fuel mixture setting on the high speed adjustment needle valve.

is there a bowl on this carb that fills with fuel, and gets sucked up or is it all controlled from the high speed needle?

SO MANY QUESTIONS!!! lol

Check to make sure the filter/screen in the outlet of the fuel tank is not blocked.....And if you have been turning the high speed needle then it could be out of wack.... And yes there is a fuel bowl with a float.....

sounds like it's too rich at high speed. Gently seat the bottom needle (clockwise), then open 3/4 - 1 turn. See if it runs better. (Low speed needle initial setting is 1 1/2 open, but probably will run best on a leaner setting.

There are no knobs on the adjustment needles so they can go all the way in and come all the way out, I guess I need to know how many turns from the completely seated position the knobs should be turned to get it to run properly, then I figured I can fine tune it from there.

Also does anyone know if there is an aftermarket carb that will work on this, the factory one is know longer available, and I was hoping the aftermarket one would be a little more user friendly lol

I think you'll find it works OK once you've set the needles per oldboat1's suggestion. I just did a full rebuild on my carb ignitiion, and my little putt putt purrs like a kitten. https://www.youtube.com/watch?time_continue=7&v=AdGI54CS4XI

No offense, but have you replaced the spark plug? I just pulled mine out of storage and it didn't run fast either. I replaced the plug and it was fixed.
