It sit about a year so the carb was plugged up i took it off cleaned it out. then check to see if it was getting spark it is. but still wont run. It has plenty of compression. but the wiring is a mess. The guy i bought it off of said that the ignition switch went out so the put a toggle switch on it . Ive looked for a wiring diagram for this engine can not find anything. So my question is how can i get this bike to run and is there a website i can go to to get a diagram? Thank you

If you have compression, and spark, and gas throe the carburetor it shude run , if the spark is good I saspack the gas , you shud poor sam in the cylinder see if it will response, about the diagram sorry don't know but if you have spark you ok , hoop I halp

If it's getting spark, electrical and wiring are not the problem. Just "cleaning out " the carb is not enough. The jets have to be removed and cleaned. Hold them up to the light - you should be able to see through them. Next possible cause would be a worn out top end (cylinder, piston & rings) - test the cylinder compression.
