Got this a week ago... oil change along with filter added coolant new spark plug... fired it up tons of white smoke out the back, checked the oil filled it up little to much, and read the coolant could be the problem with the white smoke as well... it also would not idle with out the choke so i cleaned the carb checked the jets all clean there... i did do a stock air fuel adjustment 2 turns out on the right and 3 on left... slapped it all back together and tried to start it and i got a back fire with white smoke and it wont start again... im stumped on this please help thank you. Also has hmf slip on it.

 

Ok so when i put my hand on the airbox snorkle it fires right up once i get it right so now what

 

On the air fuel mixture screw did you get the spring washer and O-ring out? Ive had people not know about them pieces and that was their problem.

 

I knew about them just didnt want to take them out cause they were starting to get difficult to turn out and didnt want to risk stripping them, but looks like I'll start from there
