On my 50, when you push the gas down all the way, there are two wires on the carb base that are connected by a little vacuum switch built in the base. If the throttle linkage isn't connected, when you push the pedal down, nothing changes at the carb end and so it won't roll over.

I don't know what year they stopped that or if yours rolls over with just the key.


Also, did you do the compression test with the choke and throttle blades OPEN? If they're closed, the cylinders won't get air and you'll get an abnormally low reading (although it's usually like 30-50% low, not 99%).


If you have to, open the choke gently by hand and open the throttle blades and put something in there to hold them open, but don't force it so it doesn't bend anything. OR you can take the carb off and be done with it.

Of course if you have a carb style switch, disconnect it as it will start rolling over if the key is on and the throttle is open. Then i'd leave the key on, unplug the coil wire from the cap, and use those two wires as my remote starter switch.
