Jetting or fuel depletion to the engine. The fuel and air mixture need to be balanced out with the intake. Mess with the air filter and air-mixture screw/jetting. Report the result and maybe we can work something out!! :D

Engine and Carb quick check list - TBolt USA Tech Database!

Install Intake manifold to head and carb, oil gaskets and tighten bolts lightly at first then torque then down gradually in a cross pattern to provide a good seal and avoid air leaks

1)Throttle cable adjustment check:

a)Carb slide MUST hit bottom 

b)Test it , You MUST hear the sound of the slide hitting the bottom of the carb

c)You must have free play or slack in the throttle cable 

d)You must be able to turn the throttle a small amount WITHOUT moving the carb slide

2)Make sure the carb is 100% clean, free of debris and you can see light thru both main and pilot jets 

You must start with a known good and properly oiled air filter 

3)Double check you valve tappet adjustment .003intake and .004exh. 

4)Make sure your exhaust gasket is installed properly. 

5)Make sure all electrical connections are tight and you have a solid ground from the engine to the frame.

and make sure you have spark 

6)Check for good fuel flow and fresh fuel. 

7)See our jetting guide and do a plug read.

Flooded Engine:

IF your flooded , pull the plug , Kick it over like 10 time WITH THE PLUG OUT 

Put in a NEW PLUG

One more thing

I find at times it helps to just crack the throttle a tiny bit to let air in , just a tiny bit

Adjusted my tappets and seems to have worked, not been out on it properly yet, my intake was to tight, and exhaust was well loose
