Larry, That would be a good idea to check bowl for gas and maybe adjust float level and drop but you really, really need a rebuild kit. Possibilities include (some have been stated already) Your bowl is emptying, accel pump bad, needle valve problem, too much fuel pressure (wrong pump), clogged filter, dirt in system/tank which keeps clogging somewhere, fuel lines, (rubber or steel) are sucking air, tank vent blocked, gas cap seal... Remedy: 1. Do a standard fuel pump supply/volume test (and also observe container for dirt). 2. Rebuild carb. 3. Change fuel filters. It will then start right up. A brand new or rebuilt carb would be great if you can afford, but screwing around with trying to figure out what part(s) inside carb is bad is a big waste of time! Usually if the engine will actually start and run up and down hills and under load and so on and the fuel pump does not leak, it is NOT the fuel pump. When you "break the seal" at where the fuel line attaches to carb and it visibly squirts out, the diaphragm in pump is good. Keep us "posted".
