 |
|
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?

| 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.

| 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. |

I am having the same issue, my '65 Ghia starts up fine but then stalls at every light after 5-10 minutes or so. I dont really know my way around engines but I can check the points and plugs. Dont know which one is the heat pipe or manifold? Judging by the rest of my car when I got it recently, its been a long, long time since anything was changed. The oil was gray, sludgy and smelled like gas, never seen anything like it.
I wonder if I should just buy a tune up kit and see if that helps some? How do you know when you need a new distributor cap or points?

If you don't know the history and the tune up parts look older, I would go through and replace everything and do a complete tune up, including belt and plug wires. Save the old parts for emergency spares.
First determine which period engine is in your 65. Start by getting a corresponding service manual. Bentley Service Manuals are excellent. The Blue Bentley is for the 66 - 69 Type 1 Beetle and Ghia. If your car has a later 1600 Engine, 70 and later, you'll want the orange Bently. If your car has the original 1965 engine, I don't know what manual you would want. Also search YouTube videos for how to do a tune up for VW air cooled engines.

I bet the diaphragm in your fuel pump has ruptured. A fun endearing quirk of these cars is that if the fuel pump diaphragm ruptures (often from debris from the fuel tank), the fuel will go straight down into the engine case via the hole for the fuel pump pushrod. Then, rather than lubricating your engine bearings with oil, you're cleaning them with gasoline which will of course shorten their life dramatically. This is why it's a must to run a fuel filter before the fuel pump, not after it.
If it's a small rupture, the pump can still deliver enough fuel to the carb for it to run, while simultaneously washing the engine bearings.
I would do a couple of oil change flushes in succession just to be sure you get all the gasoline out.

If you look at the carburetor it is bolted to the manifold (a pipe that goes to each side of the motor, under it is the heat pipe it goes along under the intake "tube" and heats the manifold. On a cold motor start it then carefully reach under the manifold and feel the heat pipe, it should get too hot to touch after a few min.s if it stays freezing cold that's why the car stalls when you come to a stop and the heat pipe is clogged with carbon and needs to be cleaned out. |

I dont know it does, but I will find out. thank you, and thanks to the other responses. I will act on them.

I just started the Ghia, and the heating pipe on the right heated up quickly, but the one on the left didnt get warm at all in 4-5 minutes. So I guess its clogged somewhere in between?

A cold manifold will cause the vaporized gas from the carb. to liquify and liquid gas only burns while vaporize gas explodes thats why when you come to a stop liquid gas enters the cylinder's and "puts out the fire" causing the motor to stall, you need to clean out the heat riser. |

Is it quicker to remove the muffler to do this or remove the pipes from the top?
