Why is it that my California trimmer will not start up. I clean the gas tank and the carburetor, any suggestions?

Based on the context, the likely reasons your California Trimmer mower won't stay running, even after cleaning the gas tank and carburetor, include:

1. Clogged or Dirty Carburetor: Even if cleaned, internal passages may still be partially blocked, preventing proper fuel flow.

2. Bad or Leaking Gasket: A failing carburetor gasket can cause air leaks, leading to poor fuel-air mixture and stalling when the choke is turned off.

3. Fuel Tank or Fuel Line Leak: If the tank or fuel line leaks or isn't sealed properly, it may prevent consistent fuel flow.

4. Improper Carburetor Installation: If the carburetor is not tightened correctly or aligned with the gasket, it can cause vacuum leaks.

5. Old or Contaminated Fuel: Even after cleaning, using old fuel can cause poor performance. Make sure to use fresh fuel.

Inspect the gasket, check for vacuum leaks, verify fuel flow, and ensure the carburetor is fully cleaned and properly installed.

Based on the context, possible reasons your California Trimmer mower won't start after cleaning the carburetor and gas tank and adding new gas include:

1. Contaminated Fuel: You mentioned seeing small clippings in the tank. Even if it's not "overly" dirty, debris can clog fuel lines or the carburetor.

2. Oil Overfill or Fuel in Oil: Oil started coming out when you opened the dipstick, and you noticed a gas smell in the garage. This suggests fuel may have leaked into the oil, which can prevent the engine from starting.

To fix this, drain and replace the oil, ensure the fuel is clean, and check for any remaining blockages in the fuel system.
