Pocket Bike Problem

[bcrichguitars]

Hi, I'm new to this forum and to pocket bike racing. I have a problem though. Ihave been running 25:1 with premium gas and castrol 2 stroke oil but i have ran about 5 tanks and now im getting a problem. I can't give my bike barely any throttle before it tries to stall I thinks people are referring to this as bogging out but is this because its running to rich? Will putting 50:1 or using synthetic 2-stroke oil fix this problem? If not what else can I try?

Thanks In Advance

Should Of Switched to 50:1 At about 3 Tanks.

a blocked jet, from new there was probably something in the tank and it has gone down and got stuck in the carbi

yes, plastic shaving got stuck in my carb, at the float needle valve, the float couldnt close properly and my carb was overflowing with fuel, i have lernt a new trik if this happends 2 u, hook up a 1/4 inch hose to the front of a blow gun on a compressor, pull of the fuel line, plug it, or clamp it with sumthing, put the other end from the blow gun onto the carb with the fuel line was, remove center bolt on botom of carb bowl, and slowly blow air in, not to much, they werent made for 100psi :wink:

I would have switched at 3 but I was just trying to follow the manual.
Thanks everyone for the help

I got my pocket bike yesterday and Iam doing 25:1 I have done about 1 mile in it(1/8 of a tank?)

Anyway most of the time at low speeds and I suddenly floor it it cuts out so i have to be real quick and let go of the throttle. But at high speeds its fine. If its not the mixing ratio it might be becuase of the gears.

And this morning I put a ratio of about 18:1 and it worked (poured to much in).
