I have changed gas rebuilt carb changed spark plug and it will crank and run good at idle on half choke until you throttle up and it bust up.the valve train is a little noisy also. any suggestions.thanks

 

It sounds like your valves need to be adjusted, especially if there is a noise problem that you are noticing.

 

thanks dwill58,I did adjust valves and it quitend them down but it still will not run off choke.where can i find a carb breakdown.thanks
