Well, back in the day when I had my plane, the oil drain hole on one of the engines lost its threads. These are cast aluminum or maybe even titanium oil pans and removing the engine and oil pan to re-thread the drain plug hole would have cost about $5,000, mainly because the FAA requires that all non mandatory service difficulty reports must be done if the engine is taken apart. If the drain plug could not be re threaded, then another $5,000 would buy a new oil pan, so, like, maybe $10,000 to fix the oil drain!
So, my mechanic....licensed mechanic....said he could legally drill and re tap the drain hole without removing the engine or dropping the pan. I asked about the drill shavings that would result from this procedure. He hesitated, and then revealed a trade secret.....he was going to run a continuous stream of water through the engine as he drilled and tapped the drain hole!!
I was there when he did that procedure. A garden hose was stuck in the oil filler tube and a full pressure stream of water was pouring out of the oil pan drain hole as the mechanic carefully drilled and tapped the hole!!
I flew that plane for another 5 years without a problem. Made it to TBO.
The moral of the story? Water is OK in an engine....just don't start the damn thing!!
(and, you'll really surprise yourself at what you will do to save $10,000.... ;D )

In the 70's Edelbrock came out with a carburetor water injection system. It was a good theory -- inject a precise but varying amount of water into the carb, which would cause the fuel to disperse and give a more even and complete burn, resulting in better power and fuel economy -- this was during the original gas crisis. Problem was, it didn't work. Anyways, I put one in my V-8 360 Dodge truck. One day the water hose came off of the nozzle, and water got dumped into the carb until the engine died. This was while going 65 on the L.A. freeway. I pulled over and cranked the engine with one plug removed at a time to blow out the water. Sprayed some starter fluid into the carb, and it started right up. Drove it home to San Diego (I was in the Navy). I drained the oil, and there was a LOT of water in it. But my carb and engine were really clean... Didn't do the slightest harm to anything, I spent many years driving that truck all over the country.

joshua: The regulator/rectifier unit I got from Mikes PMA has closer hole spacing than original. Are we supposed to mill the holes to fit?
Jun 7, 2017 19:25:58 GMT -5
joshua: My bad. I found the bracket they supplied to mount the rectifier/regulator... Uh oh. How is this meant to work? Which way is it meant to mount? Looks like I have to use some spacers or something. Good instructions would be nice.

craig8johnson: I'm checking the charging system. I'm afraid I might have fried the last battery. With the solid state regulator (after market) what should it be charging at. The book says, I think, 15 volts. I'm hitting 17 when revved. Is that too high?
Jul 11, 2017 18:06:19 GMT -5
gggGary: Yes 17 volts is too high, about 14 volts is max, sounds like you don't have the right regulator or it's wired wrong.

tt650: Trying to breathe life into a 1980 that's been stored (indoors) for 25 yrs. Air filters are dry rotted. Have cleaned carbs but she only runs briefly on choke then stops. Need jet setting info and other ideas that might help her idle and rev.

trix13: Hey everyone! New to the forum and am fighting those gremlins!! New charging system, ignition switch, coil and fuse box. Resistance is higher than normal on the ignition pick up so I'm trying to find one. No such luck yet.

jimothyj: Hello everyone, I just joined & wish would have known about this site in 2014 when I brought my 1974 TX650A back from the grave. I have spent a good deal of $$ and alot of time on it. Just painted it and working on electrical, I will post pics soon,

louisvan: trix13 - I had a problem with my 1975 SX650. When I got to highway speeds, the engine lost power. The problem was in the connectors. At a certain vibration and the wind pushing on the wiring loom, the connector lost continuity. A bad crimp to the wire.
