Bro!! Even when you know how to work on these, sometimes you run into an issue that you just can’t figure out. The next step is to listen to others. You saying the words “vacuum leak” made me look past the carb and realize that the gasket was ripped apart and sucked into the intake. I was over here doing everything I could to tune the carb. I noticed when the mini bike would go full throttle on choke. Thanks for the video!

Valve cover gasket was ripped on mine. Ripped from header pipe bracket made a tear. Spent hours on installing new carb, jets, other gaskets. Finally got it going now going to try tuning.

@@nathanbostic7039 The first step to diagnosing a bad running engine with a carb is always to soak the gaskets in carb cleaner or brake clean and see if it revs up or bogs down. If it does, that's a gasket leak.

Just getting into these clone engines , currently have a predetor ghost for my sons go kart . I have a ton of experience building and tuning 2 strokes and seems a lot of the info is the same . I have noticed the trend of running short open header pipes and these silly vm carbs , out of curiosity I want to try using modern 4 stroke mx design on these as well as different carb types like a flat slide or a pj . Also I remember having a carb on my HD that hat a 3rd jet for high ram wot maybe that could be used or the basics of it implemented on one of these . Definitely fun little engines to tinker with .

Your Parts carburetor is a real Mikuni, you notice the slide is much larger, All Chinese made Mikuni carburetors have the small bodied carburetor, even if it says Mikuni. Example the one on your bike is Chinese and it can’t say Makoni because I have one. Anyway your camera is fine you’re just too close to it ha ha ha

@Deucealive755 ай бұрын
He has it correct in the video. When the screw is on the intake side of the carb, it's an air screw. When on the manifold side, it's a fuel screw. On these carbs it's a fuel screw. Same thing on the stock carb. On the stock carb the screw is after the pilot jet in the circuit. It's a fuel screw.
