Racing Carburetor 2 Stroke 49cc 66cc 70cc 80cc With Air Filter For 2 Stroke Engine Motorized Bicycle RED

Works great except was not enough room for the air filter and my frame.

I couldn't believe how affordable this was when I bought it and so easy to install less than five minutes. It was harder getting the original off than it was adding this. The fit was oerfect. If your looking for a little boost this is the part for you! Faster than I even needed bought this a while ago but was taking the time to review some of my older purchases and this carburator is a beast. In fact be Xtra careful with any kind of motorized parts and equipment because even the littlest mistake amcan lead to injury so remember SAFETY SAFETY SAFETY ( got a spiral fracture on my left ankle that took almost a year to heal but it wasn't the carburetor's fault so have fun but always follow safety rules and wear safety equipment whenever possible.

Assembly wasn't too hard. The paper gasket between the carburetor and the throttle assembly popped out when I took it apart, but it came back together alright. There initially wasn't enough clearance between the stock intake pipe and the seat tube of the bike for the carburetor + air filter so I had to reseat my engine with the carburetor on it so that it would fit. The fuel outlet from the gas tank was on the opposite side of the fuel inlet on the carburetor, so I had to snag some extra hose to get it to go across. Compared to the stock carburetor that came with my engine, this one idles much smoother and doesn't stall. I can't say I've seen a gain or loss in power compared to before, my engine still needs to break in. This was one of the, if not the, cheapest option out of all the listings for this carburetor since it does not come with any other pieces other than the carburetor and the air filter. I'm not dedicated enough to these engines that I'd go and replace the jet in the carburetor, so the right jet size is up to you. I haven't seen any problems with the stock jet myself.

Unfortunately it was raining when I received the new carburetor. So I never had a chance to try it before. I ran out of time to send it back. when I first opened a package it smelled like cigarettes. It was extremely hard to assemble. No instructions I had looked at it for about an hour to figure out how it worked. There was a broken gasket between the throttle connector and the body of the carburetor Don't know if its leaking air into the carburetor from that point. I tightened down the 2 screws tried the throttle it was stuck I disassemble the carburetor and found that the spring wasn't mounted properly I didn't run the cable through the spring. My fault. Had to change the throttle handle there was too much Slack in it. i had extra throttle handle i hooked it up and at work right. Lost power. Better gas mileage. Top end was slower acceleration slower, no power going uphill. Don't know if broken gasket has anything to do with this too late to send it back stuck with it

I've been trying to fix up all my toys for spring, ended up needing a carb. I looked around and this is the best for the price. I have likes and dislikes, Its starts super easy, the choke doesn't vibrate itself out of place, it is a good increase in filter size, and it doesn't stall out at low speed as much. Its jetted a little low for me, my top speed is 15 mph lower and I'm now at 22mph. For installation its pretty simple there is no need for instructions, just use the adaptor and pipe tape (tape up the inlet tube and put adaptor over and its good to install). AND DON'T OVER TIGHTEN IT, most people who own these bikes don't have mechanical experience and they don't realize no matter what your engine and all parts for it are probably Chinese so you need to just get it snug. And keep your old carb you might need to switch the cable holder.

choke is cheap and doesnt always stay when starting, filters are impossible to find, stock filter will get lost or rubber will fail and filter will fall off. ended up taking a mason jar lid, some metal zip-ties and a piece of foam filter material and ended up making my own filter that's stayed put with no problems. besides that bikes run great except for the issue with the choke.

Arrived just as described. Everything works and it started up immediately way easier than the stock one. It has a really nice idle as well. Great carb. Not sure the power difference yet because I haven't gotten to ride it more than a couple of minutes. Works great though. I ordered the intake elbow to account for the bigger air filter as well. That's why you don't see it on. Fit. Perfect.

Perfect, is the product I wanted and needed

This has turned into such a fantastic hobby. Ive been riding dirt bikes since 4 years old couldn't even touch ground when on it. Anyway i thought i would try an engine on a mountain bike. Wow! I couldnt believe it. Just a 66cc china toy motor on a 26" Huffy from 1989. After all done with some modifications of course. Motor ran ok but i wasnt able to get it to idle on its own. Before i even thought about the the main jet I ordered and installed upgraded to HP carb. Right away noticed a difference and motor idled on its own with no tuning. But soon relised i had very poor high end rpm. So i found out from the Awesome people that do videos on you tube the new carbs come with a jet not right for the climate hear in ontario. Long story short ordered 5mm jet set and installed a 68.. had a 72 i believe.. took it out for a run and it wound right out to max hp and cruises nice at 32 kms an hr..bike runs fantastic. Since then i discovered that the NT carb can use same jets and works good to.. Definitely recommend the Hp carb for the better filtering and easier air flow.. little 66cc motor really puts out. Ill add pic when I get home..

Do not but this product it is junk. I bought it and used it the clamp attached to the carb broke off making it unusable.

Great purchase. Had to do a little modification for it to fit. The NT cable end was too big for the hole in the valve to sit properly. I just filed down the tip and drilled the hole in the gate take it fit. I also had to change out the cable attachment on top of the hp carburetor with the NT carburetor. I put at #65 Jet in the new carburetor and OMG what a difference. For 25.00 you can buy 2 and keep a spare. Do the modifications before hand and you never have to worry. The bike idols so much better and there is less vibration over all. The needle in this carburetor is bigger with more air flow. Just do your homework before you buy. Its not a plug and play setup but is way better than the stock NT. Nothing wrong with the NT but this carburetor runs so much smoother. I just ordered another one. This video shows the smoke in the exhaust with the stock NT and quite alot of vibration. This carb has less smoke and vibration. Im still braking in the motor but it's getting better.

Cleary the people who wrote one star reveiws dont know what they are talking about. User error does not mean this carburetor is junk. This carb fit perfectly on my 70cc tomos a35 moped and definitly gave it more power. I also have the same carburetor on my motroized bicycle with no issues.

Good enough to make my bike idle 200 rpm lower and produce more low end torque, made going from a stop much faster, didn't really change high end much, but throttle response is definitely better with this carburetor, can feel power the moment I move the throttle instead of it feeling a little laggy Overall pretty good purchase, but tuning it with different size jets is never a bad idea, could end up with an even better carburetor just by making the jets slightly bigger or smaller
