Hi,

I've posted before about this problem, but now think it is an electrical issue. Hope someone can help me out.

My model is the 4 cylinder Stromberg carb version of the 230... it was purchased in Germany and brought to Canada.

The problem is the engine cuts out under load at low RPM's (like at a stop, when around 700 rpm). Then when you step on the gas is stutters before it stabilizes. This is completely random and I can't tie it to any specific occourance.

I have changed everything electrical, which includes: Spark Plugs, wires, distributor rotor and cap, ignition coil, points, condenser etc... and the fuel system is perfect (new filters, clean tank, rebuilt carb)

One strange thing that I noticed was that a brand new set of points, after only about 200 Km's, had burning and scoring. I've replaced it, but it's still not the problem.

There is a run-on solenoid on the intake manifold, and it runs slightly better when disconnected, but isn't the fix.

Anyways, does anyone have any ideas? There is no ECU and I've checked the basics of wires and connections. Looking for bright ideas.

Thanks!

burning of the points usually indicates a faulty condenser. id be tempted to try another condenser first

This sounds like a fuel related issue....however....

Change out the condenser and the other thing with this particular unit....add an inline fuel filter if you have rebuilt the carb.

Ive done plenty of work on this particular unit in the past. Also check the distributor and make sure that the vacuum advance is working properly. \You can do that by using a timing light and checking the timing whilst reving the engine.
