Carb works good engine cranked on first pull idles good
Carb works really well paint seems to be gas resistant only thing I don't like is that they painted the inside of the bowl and inside bottom of carb but as long as paint is gas resistant then it should be good I'll be keeping a eye on it but other then that it's a good well built carb alot better then I expected the boot that it comes with the bolt hole patter is to big for honda gx340 so have to make or get a diffrent carb manifold/adapter but still is a good carb for the price

It's a deffinant buy
I was having issue after issue getting my nighthawk swapped go cart running but I after I swapped this bad boy on if I so much as breathed on the starter button it would fire and run no choke required I didn't notice a huge change in low end Power but huge acceleration gains in mid to high end with about 10 to 15 mph gain overall could be the old carb needed jets but this one was half the cost of a rebuild and far easier to tune and black and red look real nice

Tip to fix flooding
Great price for this carb but you get what you pay for.Many of the machined holes have flash sticking off of them. May cause some minor performance loss.The biggest issue I saw was flooding. The seat is pressed in and I'm not sure if you can replace it. Despite having a viton tipped needle, it leaked like crazy when I hooked up the gas line.There is a pretty easy way to fix this flooding issue. You need about 10 q-tips (cut in half) and some Brasso brass polish. Take the carb apart and chuck a q-tip in your power drill. Apply some Brasso and run it in the seat for a few seconds. Repeat with all q-tips and you can get a mirror-like finish that seals much more reliably to the needle. Don't forget to thoroughly clean all the Brasso away before reinstalling.

Looks good but doesn’t fit
The adapter is too big to fit on a Chinese 110 would probably request refund soon other than too big it looks amazing

Needs more jets
38 pilot 110 main. Used on a 150cc grom clone. Will need a jet kit. 38 slow jet is too much z from my tuning I needs a 32. Main jets probably a 100 size. Other then that it’s pretty nice for a cheap carb and he’ll alot better then the stock one. Really feel the difference in cold start alone no chock needed. I need more tuning 2/3 left to mess with. But I tell you very noticeable change.
