So basically it was running mint, I added some gas and 2 stroke oil. ( just did a random guess on the ratio) started er up, drove for about 10 min then it started to bog out when I tryed to accelerate. Any ideas? Could it be the fuel ratio?

Most likely a dirt or clogged main jet if its a reed port engine, and could be a carb problem on a piston port engine too.

Could it be the gas oil ratio?

Sounds like your fuel to oil ratio guestimate.....Its wise to buy a single gallon and mix it as per ratio mix instructions of ounces to a whole.........

Would I have to drain all the gas?

I would mix a whole gallon then drain whats in the tank into the can,,mix well and then redistribute.........

ive guessed on the ratio before when i didnt have a choice. more oil is better than not enough. hopefully you didnt put less oil than you should have, it could have overheated.

mix it properly and try again, if its not running then you might want to inspect the piston and rings

I'm using AMSoil racing oil, I can tell by the color of pink what it is,lol.

So I got it going. Changed the gas, proper gas/oil ratio. Ran mint for about an hour then started cutting out again. Tryed it again today, worked for the first acceleration, let off the gas and went to accelerate again and it bogs out again. Same gas and oil

Does anybody know what could be the problem? I'd love to drive it again

sounds like your carb loosened up,,the intake cracked or theres a reed problem

 

[autoc-o1]

So how can I diagnose what it is

Get it running and spray Carb Cleaner slowly around the Intake manifold.. (That plastic thing you said was smashed).. If it dies, try again in the same spot.. If it dies again you have a manifold problem. Crack or Gasket..

If it stays alive, take out the reeds (under the Intake manifold) hold a light behind it see if you see any light around the reed flaps..

Could be your Clutch also.. Maybe its dead?

Did you see if the carb was tight like cam said?

Does it run fine until you open up the throttle? Sounds like the carb needs a good cleaning, improper mixture can jam up the jet with gunk. Those chinabikes usually use a monojet carb thats Easily blocked

 

[EPR]

If your main jet is clogged or dirty it will not run or run right. Drop the float bowl and unscrew the brass jet and clean everything.

Yea it idles perfectly, and will run about 10km/h max but cuts out when you accelerate more

fuel restriction,,,improperly set float ,,bad reeds,,bad sparkplug or misjetted carb...

Okay thanks, I'll try to figure It out
