I recently bought this original Merc Monterey with 30K miles. Got it running pretty well but it still is a little rough. Changed the ignition to solid state and put in new plugs but still have trouble starting sometimes. Still 6V system and am reluctant to change to 12V for a number of reasons, mostly having to do with compatibility of lights, gages, accessories, etc. Put in an auxiliary, switched electric fuel pump to prime the system but still have problems starting. Have not touched the original carburetor. Have been using 87 octane gas with 10% ethanol. Could this be causing a problem? If you have had any experience along these lines and have suggestions for a remedy I would be most appreciative.Thanks. /rt

You didn't say just what the problem is. Turns over slow???? Just won't fire right away????
With a 6 volt system. you need to make sure that the wiring is ok. Check all grounds to make sure that are not rusty or otherwise not making contact. Check the cable battery cables and the cable going to the starter. They should be heavy gauge, not the 12 volt size. Check the battery connections.
10 % ethanol gas isn't the problem.

Sounds like the carb is draning back when the car sits, common problem even wth electric fuel pumps. One question, are you sure the electric fiel pump is 6 volts?
Also check you timming, could be to far advanced or retarded.

Thanks for the suggestions, Paul. I'll try cleaning up the wiring connections. It turns over slowly and sometimes wears down the battery without starting. Don't think timing is the issue but I'll check this. What do you think of the 6/12 start/run system as a solution?

Two things. I had hard starting problem on my 55 Fairlane...
Make sure you have the lead wires on the coil correct. Somebody switched my car from 6V Positive ground to Negative ground and didn't change the leads on the coil. It would start about 70% of the time and I had no faith in driving it anywhere. I finally figured out the situation (read something on the internet somewhere) and switched the coil wires and now it's a reliable starter. When I say reliable start, I mean it will start every time. If I leave it sit more than two or three days it takes 8-10 seconds of cranking before the gas gets to the carb, but it always starts. If its only been sitting overnight or maybe a couple days it will pop right off.. When it's a cold start, I have a manual choke which I pull out all the way and never touch the accelerator until it starts, then push the choke most of the way in almost immediately. On a warm start no choke and also no accelerator.
I also tried the electronic ignition. Pertronics. It would not develop enough spark to start the car when the engine was cranking. Tried everything, but eventually went back to the points. With the Pertronics it would crank and crank and nothing - except when I let up on the starter - sometimes in that split second it would kick. Sometimes it would even start, but I just could not get enough voltage to have it start while cranking.

Another thing that I should have mentioned. Do you know how good the starter is? It could be going bad. Have it checked out.

More than likely it was not the Pertronics. What you describe sounds like the wiring was not hooked up properly, quite often in this case it was the resistor.

Could someone have put a 12 volt starter in the car. If all is correct and it still turns over slow, have the starter rebuilt, could be bad bearing in starter. I've had many 6 volt Fords, and except for a few bad starters all stated with no problem.

When you check the grounds, as mentioned above, use an electric contact paste. It's a lot like anti-seize, only copper based. Make sure the ground has a direct path from the battery to the starter, even if you have to run an additional strap. The ground paths thru the body/frame structure were good when the car was new, but who knows now. You can't do too good a job of grounding. No paint, no rust, clean crimps or solder on the cables. It's easy to do the hot side, and miss the grounds.
The post on the Pertronics and the resister rings an old bell. With the key in the start position, the coil got no power, but it did in run. Don't remember if it was on a Ford, or something else. But I remember the car starting when the key was released from start. Freaked me out for a while.
