Yes, and if it has that stinkin' vacuum fed fuel line, make sure you got it bled out and fuel is getting to the carb. don-ohio

1.check for spark

2.check for gas in the float bowl.

2a. because gas in the fuel line does not mean that gas is getting into the carb.

3. If the tank has the vacuum fed fuel line (don-ohio) there is a bladder in the petcock that may be torn.

4.If you do not have spark your points may be closed or if it is electronic ignition you may be out of time or loose so it is searching for a compression stroke.
