It just won't run?!?!?! GRUBEE Gt5

Use 24:1 for the break in & 32:1 after that... (16:1 is for using 30wt motor oil)

A wet plug will make it not start!! Make sure it's dry & don't use the choke... (choke lever on carb 'down')
Pedal fast, release the clutch lever fast & keep pedaling!! You should hear a "putt putt putt" sound as the engine spins from the pedals!!! If not?, your clutch is slipping.

Yeah. Since you're plug was wet, it probably means too much fuel. I would place the c-clip higher on the needle by at least one notch. Many start with it on the second notch down, but mine has to be on the top notch...

don't worry about the needle setting till after you get it running. changing the clip won't help it at all if it won't start.

One thing that will help in starting a difficult bike is to start at the top of a big hill!!!

hmm...

It occurred to me that what with today's fuel injected & computerized cars that ya may not know a simple trick for startin' a partially flooded 2-smoker - along with Venice's "big hill" (or at least determination heh) - try holding the throttle at least half to all the way open while trying to start it (choke off ofc if the plug is already wet).

While it does let some more fuel in, it lets a LOT more air in and may be jus' the ticket to gettin' her started for the first time as you do have both fuel & fire *shrug*

Make sure your Carb is as level as you can get it, a buddy of mine had the same problem and turns out he had his carb mounted at an angle so the floats were not kicking off the fuel flow, and it was flooding the engine.

SAME PROBLEM:

I just built my first bike with a Grubee GT5 Motor, took it out and it fired up right away with a 16:1 fuel mixture (like recommended). My problem is that I can’t keep it running. If I turn the lower petcock lever all the way to open it feeds way too much gas into the carb and it ends up flooding and dripping out like crazy. So I’ve figured out that finding a “sweet spot” with the lower petcock (located on the carb) is the way to keep it running if only briefly. But even this doesn’t even really work. It starts fine, and idles fine, but after about 5 min of riding it will die. It either chokes out or floods out. I can get it started right away again my messing with the fuel line(increasing or decreasing flow) but this is super frustrating. Again, I can start it and ride it and it runs great, super smooth and really quite fast. But after a couple trips around the block it dies. I then either shut the fuel off fire it up and ride it again, or give it more fuel fire it up and ride it. But then only to have it die for the same reasons blocks later. Is this typical of these things? to be super unreliable during break in? or am I doing something wrong? Is my fuel mixture wrong? Do I have something set up wrong? Is there an adjustment I’m missing that will keep the motor taking the gas and not pissing it out of the carb? Someone help, im going crazy! And my legs are killing me from pedaling this tank.
