First off, wanted to say hello and thanks for the information provided here thus far. I have a new (2010) 66cc/80cc 2 Stroke Motor Engine Kit (Grubee SkyHawk GT5) mounted and ready to go. I could snap my fingers, and the bike fires right up, idles, and even revs just like it should. The trouble is when I go to ride it, the motor will run up until about 1/4 throttle, then it bogs down and dies. I really don't even need to use the choke, it fires up every time. I have messed with the 2 adjustments on the carb and tried the pacman clip on the stock location, the leanest setting, and now it is on the 2nd from teh bottom running rich. Still idles great, but dies when I ride it. Anyone have any ideas? Thanks in advance.:-||
 
Are you using the pedals to build up some speed before letting the engine fully take over?
How much oil are you mixing in the gas?

I barely have to pedal at all to start the motor. My fuel mix is about 17:1 to break in the motor.

After the engine is started, you still have to pedal to help the bike get moving! You can't just take off from a dead stop using only the engines power... Try it. :)

Also, use 24:1 for the first 2 gallons to break in the engine, then switch to 32:1. (Too much oil can cause poor performance.)
 
Thats what I do. I continue to pedal. I'm wondering when it bogs down if that is too much or not enough gas? I'm leaning towards not enough? Just weird that it idles and revs at a stand still perfect, but when you put a load on, it dies.
 
I will give it a shot tonight. Thanks again. You getting snow down there? Looks like you guys are getting all kinds of weird weather!
 
There is a screw on the side of your carb, if it is the carb that I have, just turn it in screw it in. See what happends. remember how many times you screwed it in and if it does not make a difference you can screw it out the same amount.
 
It turns out it was the mixture. The manual called for 18:1 mix....should have known with how terrible the instructions are! Changed it to 24:1 and it ran like a champ. Got it all painted and it turned heads all weekend! Thanks again for the help!
