Seems like there is a pickup that extends down into the tank that stops just short of the bottom and it looks like it pumps fuel up there and what it doesn't need just falls back into the tank? It's funny, I always thought these old carbs worked on a siphon effect but this thing sure seems to be pumping a large volume of fuel around in there. Is that the way these things are supposed to work. there was a large steady stream of fuel dumping out the bottom of the carb back into the tank. With the motor running I removed the gas cap to see if it behaved like the cap was causing some restriction and I noticed that the thing pumps a lot of fuel. This carb has the welch plug on the right side of the carb and a big one on the rear.Ībout the pickup down in the tank. With the governor bypassed the engine would run lean at the factory settings but I recall there being an adjustable mixture screw that I could tune.

PULSA JET CARB HOW TO
Back in 1966 when I got my first Taco mini bike it had a 3hp Briggs and it didn't take long to learn how to disable the governor. These old carbs have changed since I was a kid. I checked all the gaskets to make sure there aren't any leaks in the intake tract and all looks good. If it was a two cycle pumper carb it would already be fixed LOL haven't run or worked on one since around 1967 so bear with me. I know very little about these old four bangers. That is odd because a backfire is usually from a rich mixture on the run down. if I get this engine revved up past the flat spot and then let off sometimes it will backfire. Since this setup has no adjusting needle or fiber washer.Īnother thing to mention. 019".īased on Freezeman's description I think he is talking about a different type of carb. The controlling orifice down through the center of the jet is about.

On this carb the jet screws in and seats in a fixed position and there appears to be no adjustment options other than to the drill the jet.

Here's a photo showing the location of the jet on the carb and the jet itself when removed.
