are you starting with the manifold nuts missing ? That would be a reason for a no start .

John

[scooter99]

No i took them off because i wanted to see if there was fuel flowing through there and it was wet. But i put the two nuts back on and tried to start it but nothing.

[tvnacman]

have you checked valve adjustment ?

John

[scooter99]

yes both valves are at .004

Could be a clogged low speed jet. Just throwing out my .02 dollars. Have you tried starting it while spraying starting fluid into the carb throat?

Good idea , but don't use starter fluid . Use carb cleaner spray .

Any luck with the carb cleaning ?

And when spray fuel directly in the intake manifold the bike starts up with no problem. I tried cleaning the Carb but no use. i think it may be a bad carb. Dose anyone know were they sell a inexpensive carb. I'm thinking i may need one.

What scoot do you have is it a 150 or a 50cc scoot?
Also can you take a picture of the CARB and HOSES going to it they are very simple to clean and adjust.
But you may want to ask TVANCMAN if he has a carb for your scoot, he sells the stuff at very reasonable prices.

When you cleaned the carb, did you remove the low speed idle jet and actually look through it to see a pinhole of light? That tiny passage must be clear or your engine won't start.

Not sure what carb cleaner you use, but Gumout doesn't combust nearly as well as gasoline, and nowhere near as well as starting fluid.

I can get a cheap carb for you , but I suggest spending a few dollars more and getting the better carb that I offered you the other day . KEIHIN !!!!!!!!

When i cleaned it i took both jets out and inspected them. Both of them were fairly clean not much dirt or anything. I stilled sprayed them and left them socking it carb cleaner overnight, With other parts of the carb.
