Hey there guys, I just put on this 80cc kit for the GY6. Now, I got it on, set the valves, timing, all that good stuff, brand new carb, new coil, whole gambit. Basically got a whole boat load of parts brand new on it.
But, when I installed the BBK, It won't start...?
Has Fuel, Compression, Spark.
now, I was turning it over, and I actually got a flame out of the back of the carb.... Ermm never seen it before. So obviously, it's firing at some point, probably not the right time. -
I have adjusted the timing 8 times now. :/ Don't know what to do.
And I did line the T and the 2 dots up. with the big hole out away from the engine ^

what size carb are you using? it really helps when you list your setup in your signature, helps us to better help you. what are your valves adjusted to?

I'd suggest an upjetting the MAIN jet from a # to around # - (within that range). # jets are usually good for exhaust mods/upgrades. Most suggest using # - MJ's for 50cc-based BBKs.

Can you post a pic of your TIMING MARKS --- pop the valve cover off, and take a pic of the T and the 2 dots lined up -correctly- Video works well too, show us
