Coleman 196 Help

[RyedOnTheRocks]

Hello all. I recently inherited a Coleman 196 kart with a Predator 212cc engine. I am having some trouble with fuel leaking from carb bowl drain hose when accelerating. This was happening with an old carb and the new one I just put on. The carb is a Mikuni style Amazon knock off. I have done some troubleshooting including bypassing the fuel pump and having it gravity fed as the tank is higher. Problem persisted. I am hesitant to make floats bowl adjustments because it is a brand new carb and was looking for any suggestions. Any help would be appreciated.

Not being sarcastic. Put the factory carb back on. The Chikuni carbs ( what you have )
have a history of being problematic. The float level may be set too high, allowing too much gas in the bowl. Especially since it's only on acceleration. Just because it's new doesn't mean it's set properly.

Post a pic or two of the carb and the float inside. Like Pancho says, the float might just be incorrectly adjusted

Thanks for the reply’s. Is the float adjustment done by bending the little tang the needle hangs from? I will send some pics when I go to make adjustments.

We could tell you if the float is off if you post a pic of the carb with the bowl off.

Bottom of the carb needs to be clocked at about 2'oclock and the top should be about 7'oclock.

Get the floats and the needle in the pic.

The idea is, when the carb is inverted, the needle stops in its plugged position, stopping the floats, showing us their position when the bowl is filled.

-But with two carbs doing this it sounds like something else. Maybe your vent is plugged?

This is the carb that came on the motor when I got it. The kart had been sitting around for several months with gas in it so I did disassemble and clean with just a spray. First pic is the assembled carb for context. Thanks for the help.

They are meant to be adjusted and tweaked as soon as you buy them. Due to variables such as air density, elevation, ambient humidity, fuel quality and other factors, they cannot be factory adjusted for every person or every situation. The manufacturing quality is another issue in and of itself.….

There’s been untold numbers of Amazon carbs sold that don’t work. Never read the 5 star reviews. Look at the 1 and 2 star reviews (courtesy of W.T.R.)

Just occurred to me these pictures might need to be with the carb in hand not on table.

I was expecting air/fuel mix adjustments but I thought bowl float would be a locked and loaded situation.
