hi, i have a 1969 honda minitrail and cant get it to stay running, when it did start as soon as i hit the throttle it died and it hasn't started since, when i checked the spark plug the spark is purple, i've heard that blue is correct and purple is weak, I know its not much information to go on but any info is appreciated

 

Did you try cleaning the carb? The jets in this are very small and even the littlest bit of dirt can clog them causing what you described

 

I would start with a new set of points and a condenser. I would also take apart and clean the carb.

 

ok, ill take the carb off and clean everything up, also does anyone know what way is on for the keyswitch, the end of the key is broke off and its stuck in the switch but i can still turn it with pliers, i just dont know what position is on it has three differnt positions, but none are labled

 

Looking at the switch.. clockwise is on.. counterclockwise is off.. I think the middle position is lights on.. but wont run..

 

ok, thanks

 

i have the carb off but im unsure on the proper way to disassemble and clean this thing, i dont want to break anything, anybody know where i can find a service manual or a diagram for it

 

Watch this..
