If you watch the you tube vid that claims this is the single best thing you can do for your horizontal engine and your original carb is gummmed up, get it. If you want to do what's best for your engine, get a genuine Mikuni. I thought in this day and age ANYONE can copy a carb. Not so. Mixture screw is in the float bowl, so get ready to refit the unit a million times. Doesn't like to run properly either, stalls all the time, which means the needle and seat are poor quality too. If you buy this make sure that you remove the pilot jet and clean it out before you fit it too. The Mikuni is SOOOO much better. It's night and day.

Was skeptical due to mixed reviews, but it works great on my Tao 140cc 4stroke pit bike and fit easily without any mods. The carb says "mikuni" I assume it's a knockoff, but build quality seems good and it's definitely an upgrade from the stock carb. I also shimmed the carb needle up 1 notch richer from stock. Idle valve is on the side, mixture valve is on the bottom (stock position or 1.5-2 rotations out see good starting points). The engine really woke up after installing this carb in addition to upgrading to a caged air filter. Definitely worth the $$ in my opinion

I've had this for a while, was very apprehensive to 'do' this operation; lol, two bolts off , two bolts on, kick and go. (bike was still warm from earlier) Well I did watch a few videos over the last two months, otherwise forget it. Turn FUEL OFF, remove fuel hose, air filter, take off two mnting bolts, (I didn't need new gaskets nor need to remove riser stem, still perfect) pull carb slightly halfway out of area, unscrew top cap , compress long spring so the cable end can come out. the long slot of the internal slider thing that houses the cable, spring and needle goes to only one way , so you can't really mess it up , don't force anything it should go in and or out very easy. remove old carb, put new one on in reverse of taking old one off, ; feed cable back through top cap, and spring. This part is tricky left hand has to hold cap , spring cable, compress the spring and hold with left hand, grab cable end with right hand , pull it tight till it can be pulled longer than the 'slider' length , fix it into the keeper hole, the one you['d removed the cable from to begin with. slide assembly into new carb, screw down cap. Put main bolts back in, snug, add air filter, fuel line back on, fuel valve on. Kick or push electric start , should start right up. Tool notes for 140cc pit bike; 8mm socket and open end, 10mm socket and open end and hand driver for both if you have them. I removed the spark plug wire to access passenger or rt side of bike to get one of the two 10mm main bolts out. Kick the tire one way or the other to get the fender out of the way so you can us a hand driver to remove the bolts. This is the same carb as the oem as best I can tell, but my oem had had a ton of hours on it so the bike was running poorly, this replacement was a night and day improvement. There's a fuel mix on the bottom , the default setting should be ok... I suggest replacing that screw before installing carb with an aftermarket fuel mix srew, they are longer and extend out with a 4 paddle numbered thumb, easy adjust end. The side adjust that they call air mix, is also called idle adjust , seems that most people tell us that if you need to adjust , screw it all the way in very gently so you don't damage it, and back out 1.5 to two revolutions/turns. Same pretty much goes for the fuel mix screw on the bottom. I hope some of this makes sense and helps someone, go to youtube for a whole bunch of pit bike or just plain 4 stroke fuel mix , and air adjust or air mix, try combinations of those terms in search and those videos can further guide you in the process. Once you've done this you'll never be apprehensive about replacing a simple carb like this one. Best to all/

I have had this on my pitbike for 5 months I beat it on it everyday and drive it in the snow. I have never once had a issue with this carb it’s amazing

Honestly I never got the chance to really break it in before my bike was stolen sadly, but as far as it’s delivery it showed up on time if not faster and I just wound up getting and using a shortly after I bought this one right before it was stolen but I believe that’s it on the bike to the right and was pretty easy to install and helped the bike run smoother for the short time I did have it
