re: 'What If Bole Is Dry'
Then it won't start, 'eh? Is that the case?
You might check flow into the carb...make sure you aren't just dealing with a low gas level...maybe the petcock needs to be on 'reserve'?
If fuel flows out the hose, but not into the carb bowl then something is hanging up the needle.
Take it apart and check it again.
The float should move freely up and down (make sure the pin holding the float is correctly installed) which will move the needle up and down.
You can check the whole mess with the bowl off...turn on the gas, manually move the float up/down and make sure fuel flows.
Don't mash on the float in the process. It only sees very light pressure.
