I have a few old motors (1930 vintage) that I was able to get running with a good cleaning of fuel system and some ignition work.They run great in a barrel.Should I go ahead and check pistons etc.just to be on safe side or not mess with a good thing and start using them?

I think you already answered your own question. THEY RUN GREAT. I would lubricate everything that moves or slides and lubricate lower unit and give it a go. Bill,

I agree with Bill, I did that with a Johnson A-50 last year seems to run pretty good on the boat too. I decided was worth a try and am going to try the same thing on a K-50 that wandered in. If you were going to be running them a lot day after day then might be worth tearing them down but for an occasional run think I would risk it.

Coincidentally,the two I most want to run are anA50 and a KA38.Both have good original paint and I didn’t want to mess it up.I read a previous post about the aluminum "spark arresters" in the A50 getting eaten and got concerned.I’m pretty sure those are fuel atomizers on the intake ports.

Don’t forget, the KA 38 requires 8:1 fuel mix!

I saw that.The first time I saw it I thought it was a typo.I’ve been doing that ratio withTC-W30 for tank tests,is that OK for longer use ?

The KA has a large rotary valve with two sealing rings on the crank so that is probably why it needs the heavy oil mix. I wouldn’t change it as they don’t make these parts any more.

the standard tc-w3 outboard oil is what I have been using,the A50 I ran at 16:1 will have to check and see what it should run. Last time out wind kicked up @ 20-25 it just pushed on through it on a 14′ boat pretty pleased.

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
