- Before starting, look down the carburetor and pump the gas once.
- You should notice 2 things: the choke valve closes & gas squirts out of the main discharge.
- If the choke valve doesn’t close, then check for a bad thermostat, or perhaps there is a linkage problem.
- When no gas squirts out, then the bowl is empty or the accelerator pump circuit is clogged.
- The bowl might be empty because it’s leaking out of the bottom somewhere, or the gas was siphoned out after turning the engine off.
- After running the engine (operating temp), turn the engine off and look down at the discharge. There should be no gas dribbling out.
- After running the engine (operating temp) and at idle look down the carburetor to see if gas is dribbling out. If it is then the check weight may be leaking.
- No gas squirting out might indicate a clogged pump to discharge channel.
- Make sure you have a vented gas cap.
