JMCHstorePerformance Carburetor W/Replaceable Main Jet For Monster Mega Moto MM80 MMB105, Carb for Coleman B100 RB100 Mototec 105cc, Motovox MBX10, Baja DB30 97cc, Phatmoto Gas Bike Lifan 79cc

This carburetor has the air/fuel mixture screw for fine tuning, also comes with a larger main jet and larger pilot jet. Far superior to stock carburetor. If you are having issues getting your stock unit to run proper use this carburetor, it will run and idle correctly.

The media could not be loaded. This is the best factory replacement carb I have found for my mm-b80 minibike. The stock carb was just too old to keep messing with. It got gimmicky over the years. Plus I couldn’t adjust the idle circuit. This new carb is the bees knees. It allows the idle adjustment, also comes with additional larger jet for updated intake system and additional jet for the other circuit in the carb. It runs great and was so easy to install. The bike starts on one pull now and idles like a chopper. Great carb with room for upgrades in the future. If you have a little 79cc Lifan engine in your minibike, this carb is the answer!

Running great! The spring on the throttle is to strong. I couldn't get it to work. I pulled off a little bit and cut it. Now it's working fine!

Bought as a replacement for an Oryxearth motor bike. Works great. Only issue is the the throttle spring is a little stiffer than the original so the spring linkage on the bike won't work. Hade to make a direct linkage.Easy to adjust with the idle screw.Works better than before. Great carb at a great price.

Ran worse than the old one, frustrating because it is hard to install on this bike, and to not have it work after all the time it takes to install is massively disappointing. Look elsewhere.

There is no return spring mounted on the throttle at the carb body. The original has one and this one does not. Performance is poor. The throttle does not snap shut when released.I am updating this review to 5 stars because the sellers customer service rates it. Excellent and speedy.

All was great works well installed simply with supplied gaskets. Little guy been speed racer ever since on his gocart.
