Then you should be steering him to the actual real BoFeng carb then Johnny...The JRL BoFeng, the same ones I use that always work and never fail...lol...lol.

Not sure if there's a difference between the 2 we posted, but in addition to being verified and authenticated yours is cheaper lol.

Did you not notice that on the one you showed that when you click onto each picture to show all sides of it, it does NOT show the side that actually shows the brand name BoFeng, spelled exactly the way I just spelled it.

You will eventually learn these little tricks like this that fool people into thinking they are buying the real deal when they are actually buying fakes.

I wanna buy it now just to see.

Now go to the amazon link I provided and click on the pics and you will see the side that shows the BoFeng name just like I have typed it...Notice where the capitalised letters are as well???.

Yup, capitalized B and F. That's like the one I have on my bike.

Just like you have read about counterfeit Phantom 85's being sold by "Hu Flung Dung" Enterprises and not by the actual owners and designers known as bicycle-engines.com that has one designated manufacturer of that motor in China making it exclusively for them with their specifications, there are also an infinite number of mom and pop Chinese "factories" producing counterfeits of motors, carburetors, and virtually everything else we use on our bikes...You have to be wary because it is bad enough that ya still got to work out the rough spots on the genuine articles, it is ten times worse when trying to polish the turd of Chinese counterfeits...lol...lol...lol.

Yeah, this is what he said.

If it won't run AT ALL without the choke 70-80%, that's seriously lean. If it's still lean at 80% choke, than maybe the mix is technically right at 100% choke. But then, obviously the engine doesn't get enough air to run. I'm figuring that's his problem. If that makes sense to anyone lol?

@Zingzing29 you oughta get this carb.

Amazon.com

Simple, cheap, and tried and true. If you get it and the engine still doesn't run, then you know for like 99% sure it's not the carb, and you're not out of a lot of money for knowing. But I'm betting it's the carb.
And if you decide to replace the carb do get that exact one I linked to, most of the ones I'm finding on Amazon are the NT or HP carbs which are not as good as the Bofengs.

That's the exact carburetor I ordered

As far as the needle setting I have it set in the middle position right now. It's easier to start with the cir clip raise one notch. I tried putting a 75 jet in verse the 70. It seemed to make the problem worse. I got no throttle. Although it ran a bit smoother.

It's tricky with the way it's acting because sometimes it'll start 4 stroking then die. At the same time though I'm getting what I think is a lean drone. It'll drone until I pull the clutch or the bike slows down a bit then it'll pick back.

If I flip the choke off an give it some throttle it'll sputter and die. Unless I flip the choke back on.

It acts like it's got a huge leak but it doesn't. It like it gets intermittent spark or inconsistent or not enough fuel.

I ordered one of these so I can make a make shift pressure tester and test it with a little more pressure than just my lungs. See if I can find some small leaks with soapy water. 3-5lbs I believe is what's recommended.
