Ignition Exhaust Advice 43 H

Now the question is, before I go out a buy parts should I buy a 12volt coil (with a resistor ?) and if so do I need a ballast, or is that what they mean by a coil with a resistor. OR should I just by a new 6 volt Batt and return the components to original.

Can anyone tell me what the part name (&part number) of that piece that is between the exhaust manifold and the muffler, or is this part of the muffler. Bolts to the ex manifold with 2 bolts (seized) and is rectangular in shape and is Broken… needing to purchase a muffler (Still waiting for my (3) manuals)

best regards (& 4th)

If you want to add a radio, additional lights or other electrical accessories I believe you will find 12 volts will be more practical. If you stay with 12-volts you will need either a 12 volt coil or a 6-volt coil and a ballast resistor wired in the power line between the switch and the coil. When I do my conversions to 12 volts I always find a way to wire them for 12 volt start/6-volt run. I do this by running a wire from the coil side of the resistor to either a 12-volt tap on switch on the starter (I buy a special switch for the rod pulls like on a C) or from the starter side of the push down switch on the M, or from the 12-volt tap when I do a remote solenoid instead of the push down switch on the M. I have found this to make for a much easier cold weather start.

My nickel’s worth.

If you are converted to 12v then you either need the ballast resistor or a coil with a built in resistor. Bob M or others will jump in here if I am wrong on this part.

From your description it sounds like your H is equipped with a distillate manifold. The busted piece is called the “exhaust pipe” (part #6 713 D) – it will be difficult to find a replacement.

The easiest solution is to replace the entire manifold assembly with a gasoline manifold (uses a standard 2” threaded pipe nipple for the exhaust pipe which can be replaced in the unlikely event it rusts thru or gets bent).

Figure on spending $120 or so for a new aftermarket gas manifold. Or you might find a good used one at a boneyard. But you will now have a solid muffler mount, and it will give the engine a bit more power as well.
