I have a 2011 2T Jonway I bought new April 5th this year an no matter what I do it wont richen up.It's a TK brand carb.an it has no needle clip adjustment on it,its also got this crazy looking spring loaded needle valve and it just hooks on the plastic float,no metal on the float at all so no way to adjust the float. I've got a 40 pilot jet an 74 main jet in it,when new it had a 68 main in it.Should I up jet it more or what? I don't know of any other way to do it. I've almost got the a/f screw turned all the way in also. Thanks for any Ideas. It's been so lean for so long that I'm afraid that I may have done some damage to my piston.  P.S. Where can I find a good carb. that will fit my 1E40QMb Minarelli Jog Type Engine ? It's been a pain for me to try an find one.  Forget my other post,I was misled on the guy that told me about those carbs. Thanks Again!! |

When you have to turn it out that much you need to upjet...or clean the carb. 74 is pushing it on a stock scoot. Mine is stock and runs a 75 and its slightly rich. If you upjetted already with no enriching theres a problem somewhere else.

The original TK carb.was rich,until I made a bonehead mistake and dropped it on the garage floor.  So I thought that I would put it back on my scoot,MAN talk about rich!! It was blowing oil and the exaust like Opec!! So I decided to put this semi used carb. on that the dealer sent me because the other one was a little too rich, now like I said this other carb. is way too lean. It's a fuel problem,got to be a bad carb.?? |

Way to lean is usually an air leak check anywhere the air could be getting in. If the screws don't work it usually isn't the carb but one of the connecting surfaces of the carb or the intake mating surface

Well back to vacuum check 101,I'm worried about a cracked head or something?? When it gets hot is when it leans out |

Have you checked the head for tightness of evidence of leaks?? You should be able to see a clear carbon trail... If it was cracked it would be visible

No I haven't really done that,when it was new I took a small ratchet and checked the head bolts, a couple moved a little,like a crack sound, no damage I guess LOL! Anyway's today I'm starting to tear it down, only way that I'll be able to see what's going on. If it's a wiring issue I'm throwing in the towel. Sure could use all the advice anyone could give me. Thanks!!! P.S. You asked me about leaks? I'll check the head as soon as I take off the shroud.

Old reed valve wasn't bad,but I still put a new one in. No vacuum leaks. Carburetor time, I haven't had no luck with those cheep made TK carbs. though. Anyone have any ideas on a good carb. ??

[replyingto=scootnwinn]scootnwinn[/replyingto]I have a slight oil leak where the header bolts to the exaust head(bad china weld) Would a very small hole like a pin size make a difference??

Yes your pilot jet is a very small pin hole and it makes a difference right? How much of a difference who knows. Where is it exactly in the header or between the header and head??

Ordered a cheap 40.00 dollar carb. from Scrappy,if it still bogs or won't start I'll know for sure it's something very serious. By the way is those Jog Type carbs. any good? Also has anyone out there had any trouble with a TK carb?
