Re: Mystery Aliment bedevils my KLC

The 3 wire generator (actually 2 + ground) and regulator is a marked improvement over the old cut-off relay that just connects and disconnects the battery from the generator. The regulator uses resistors and sensitive relays to gauge when to charge and although it is billed as "temperature compensat...

Re: Mystery Aliment bedevils my KLC

Troubleshooting is always way better with an audience. Makes you want to charge admission. If the ammeter is functioning correctly, the indication of charge even when not running suggests something is wrong. If you disconnect the battery and the meter now reads center line - no charging indication, ...

Re: Starting issues

That's a great tip on the sticking float needles. I am restoring a twin carb MCL and although I have previous twin carb experience with British sports cars, I think I will add a rubber mallet to my on-board tool kit.

Re: Sea-Skiff with 2 cracked ribs

Your repair logic sounds good, however I'm not certain on how the carbon fiber channel will work out. The area of the broken ribs is where your boat rides when up on plane and it will take a pounding as you cruise along. This is a common problem. I have a 25 foot Lyman, similar construction to your ...

It looks like a plastic prop shaft log through hull fitting.

A quality rubber hose with double hose clamps holds this to the shaft log. I c...

I second the varnish over the white seams. Knocks down the bright white and gives it a vintage look, kind of like the aged white binding on a Gibson guitar it just looks right to me.

I like the thought but not the execution of a drain fitting. With the vertical tank baffles, it is tough to suck any crap out completely but the risk of a gravity drain fed fuel leak is too much to have.

Re: Hercules MCL starting issues

An MCL is supposed to have 2 carbs unless someone either modified it to 1 (I guess making it an MBL) or someone swapped out the exhaust manifold from an MCL and left the MCL tag on it.

Re: Hercules MCL starting issues

Simple thing to check, since you seem to have spark is that both chokes are closing completely. If one is open even a little, the cylinder vacuum may not be enough to provide the richer mixture for starting a cold engine. The backfire through the carb might be from a lean mixture but after that much...

Re: Removal of a broken engine plate drive screw

You can try to drill these out but I believe they are a hardened steel and a small bit will want to wander off center, even if you tried doing it on a drill press. If you have enough real estate on the manifold, maybe moving the engine tag over a bit and drilling 4 new holes might work out better.

You would need a clamp-on type ammeter capable of measuring DC amps to measure the primary side (wire from the alternator to gauge shunt) and compare that reading to what your helm gauge indicates. You would need a clamp-on meter that can read DC current, most inexpensive ones are AC current only. T...

That makes sense, the wire's resistance is critical in the metering portion of the circuit to maintain accuracy. Been chasing electrons for over 40 years but I haven't caught them yet!
