Review on CARBURETOR COOLSTER 100CC 110CC COMPLETE by David Dober

This is a great little carburetor. I bought this to replace the stock carburetor on my son's Coolster 125 ATV. Standard carburetors don't have an easily adjustable mixture screw or needle, but this one does. That way you can really adjust it to whatever height you ride at. These machines are designed to operate at sea level and we live at 5,000 feet so they always run too rich and without enough power. I bought this carb, put the needle in, two turns on the mixture screw and started it. Let it warm up and adjust the mixture about 1/2 turn or so and then adjust the idle screw for a good idle speed. Works MUCH better than a regular carburetor. I STRONGLY recommend taking this carb apart and cleaning it thoroughly before installing it just to make sure there is no debris inside that could affect performance. For the price, order a spare and carry it with you just in case. You should be able to change it in 10 or 15 minutes max. Great deal and lifesaver to have this. Highly recommended!
