|
|
Not major but annoying… 1969 Ghia starts right up. For first like 15 minute if drive it will stall when coming up to stop with clutch pushed in. A quick pump of the gas pedal before it stalls will catch it and it will idle normally. Problem goes away after about 15 minutes of running.
Timing is fine and I checked Solex 30 pict 2 adjustments. Idle jet is clean.
Any ideas?? Thanks |

I guess I’ll have to start a search. Thanks for the advice. Only other thing I was thinking about was valves maybe. |

Have you adjusted the choke? Possibly the culprit if this happens in the first few minutes of driving as the engine is warming up.
What's the reason for having the clutch pedal pushed in when coming to a stop? _________________ Currently own:

Feel the heat pipe under the intake manifold when you first start the motor, it should get too hot to touch after a few min.s (feel under the carb. area and each side) if it stays ice cold you found the problem, the gas is puddling in the intake manifold and flooding the motor when you hit the brakes. You will need to clean the carbon out of the preheat pipe to fix it (this shows up when the weather turns cold). |

Thanks for the tip. Clutch pushed in at last minute to avoid stalling. Probably should get into habit of shifting to neutral. |

Thanks! I will check this out later today. Saw some posts on how to clean the carbon out. Not something I would look forward to. |

I think it’s this for the win. I started the engine and ran for about 10 min. First six inches of the heat pipe on the right side got warm. I could still hold it. Everything higher up stayed cold. |

Excellent... all your issues happened to me too until I cleaned out the preheat tubes on the intake manifold.
The carbon that came out made me realize it wouldn't hurt to do the clean out every 2 years. _________________ '74 Zambezi green Ghia vert, autostick, 101k

Now I have to find an easy way to do it. Steel cable with drill but I would rather leave the tubes on the car. |

You could drill a hole at the bend and drill with the cable (just let the carbon go in the muffler where it will blow out the exhaust) then put a hose clamp over the hole and drive to someone that can weld up the hole. |
