I got a suzuki lt50 for my son. It was free and the top end was all torn apart. so I got a new piston and rings, had the cylinder bored and also got a new carb and intake for it. I can not get it running his birthday is july 13th so I am running out of time! I have great spark. I did a compresion test and have 112psi. I don't know if this is right. The other two questions I have is there is a hole on the cylinder right where the carb pipe goes on. Does vaccum line go there? If so where does it go to. Also on the top of the carb one hose is for the gas inlet. What is the other one for(not the over flow line on the bottom). I think it is a gas issue of why its not starting, Because I can put a little gas into the cylinder and it will fire. Also where do you get vaccum for the pet-**** valve. Any help I can get I really apreciate.
