Hi there,
another day another problem, maybe you can help me out on this one:
- Big storm today, lots of rain but temperature is hot.
- Engine did not start easily and while running there were surges and random stumbling.
- My plastic transparent fuel filter seems empty. First time I installed it, it was kind of half full, but now looks really empty.
- Managed to keep a (more or less) steady idle.
- Engine runs much better if choke is half on. Now let me explain it: when the previous owner converted to 12v, he took off the automatic choke and installed a cable, so I have a manual choke that I can work from the inside, near the heater controls.
I am used to manual chokes from my motorcycles, so no big problem.
What I am thinking is that, I might be having low fuel flow problems, since choke decreases air flow, and that might be the reason why the engine reacts well to this, am I thinking well?
If anyone can help me identify and resolve this problem on my daily driver bug, I would be (once again) very appreciated.
Best regards,
Sergio |

"Runs better with the choke on" sounds like an intake (air) leak that makes the mixture very lean except when the choke drives the mixture back in the rich direction.

| And if its not an air leak it is classic blocked idle jet symptoms. |

Today I took of all spark plugs and they looked like this:
The thing is: am I running too rich? The mixture adjustment is enough to control this kind of problem?
Best,
