300cc Tornado Trike Will Not Run  By  lapper104 (Read 3,057 times)

No, you are going to have to adjust the FUEL RATIO MIXTURE no getting around it bud.

It is bogging when the throttle is open to much air, it is running lean. Fuel Ratio Screw is plugged and they set them LEAN to pass emissions here. As soon as the throttle is opened a lot more air comes in and not enough fuel.

Thanks Jim, I really didn't want to remove the carb but it looks like I am running out of options. When the bike died, it was running for a while and just stopped. I only have 261 miles on the bike and I am not real happy with it. It does start and idles fine but after it heats up a little bit it just dies when I give it throttle. I waited 7 months for the bike and now that I have it I cannot ride it. Very frustrating. I will never buy another Chinese bike again and will probably unload it (if) after I get it running. I will pull the carb and see what happens. I will let you know. Thanks again for your suggestions.

Yes, I have contacted them about this and the exhaust. The exhaust pipe weld was cracked where they joined the 2 pipes together and they told me they think that is the cause of my problem. Yes, it is still under warranty but they don't seem to know sh**! I took off the carb and noticed the diaphragm needle not seated into hole in the lower portion of the carb. Removed screws holding in diaphragm and there was a plastic piece with a small spring that was wedged in the middle of the larger spring and I think this piece is supposed to hold down the needle into the lower section of carb, and the larger spring holds down the small plastic piece with the smaller spring. Looking for a diagram for this carb to verify positioning of these components. It looks like the 4TS in the linc supplied by Alleyoop with the gold cover on top of diaphragm. Where can I get a break down diagram to confirm components position?

Take a picture of the parts does it resemble something like this?

Is the needle going down into the Needle GUide? and the Cylinder Slider sits at the bottom like in the picture?

Yes i Know the carb you have it is a 30mm or 32mm I am still trying to find a diagram for that one. The diagram i put up is of a 30mm carb but not like yours.

Yes, that's it! I kinda figured it out..that small plastic part w/small spring was actually inside the big spring. Somehow it worked its way far enough up the big spring that there was no tension on the needle and the needle came out of the seat in the bottom of the carb. I also pulled out the fuel/air ratio screw and ran a wire through the hole. It is back together and running!!!!!! I took about a mile ride and seems okay. Might need to readjust fuel/air mixture screw a little bit. Just happy it stays running and I can ride again.
Thanks for your help! Keeping my fingers crossed.
