I acquired this little Cox Baby Bee .049 engine with a Sal Taibi or Sherman extended flight fuel tank. it looks to have been never run either.

One of the forum members shed some light as to the large fuel tank and what it was used for.

Quote:
For the oldtime 1/2a Texaco events, the late Sal Taibi's B size Powerhouse is a very popular design. Instead of modifying the nose, designed for a Forester .29 ignition, Sal manufactured a tank mount that moved the Cox engine forward and provided the then allotted 14cc's of fuel.
So the tank you have is probably a Taibi product. The Powerhouse and Sal's tank are very popular in SoCal where Sal lived. The event is now flown with 4 or 8cc, but we still use the tank as an engine mount. Kevin Sherman has since taken over production of the tanks, so it is possible you have a Sherman version. Norm

Since the Fuji outboards have passed here on one or two occasions, I'd like to show my overhaul.
Unfortunately, the relevant pics were taken with a camera without a memory card in it....
I already posted part of this in the boating section, but I thought some of you guys might be interested as well.

I am by no means a real engine restorer, and the results are OK, but not in the same league of what you guys usually demonstrate.

What I did was strip the paint as much as possible from the lower end and engine cowling, not sure if I am going to repaint it (in fresh water, the aluminium should hold up fairly well).
Was a nasty job getting the paint out of all the nooks and crannies, especially on the cowling and the transom bracket.

Then I investigated why the gears were notchy , turning with difficulties and jamming, and it looked like the wear on both bevel gear bushings made the gears move away from each other, making the gears mesh very close to the tips of the teeth.
So I removed a slight bit from the vertical bearing bushing, thus lowering the vertical gear, and removed a bit from the output shaft boss to move the horizontal gear a bit closer to the intersection.
Both were shifted about 0.01 inch

Then it turned out I had overdone it a bit on the horizontal shaft, so a gasket between boss and bushing reduced that by about 0.004 inch, which made the gears turn more or less smooth again: these very small gears with relatively very coarse teeth (8 teeth on a diameter of roughly 1/4th Inch) were never really smooth to begin with. But at least, it is possible to put force on the gears again: before restoration I could not turn over the engine by the prop, after restoring gearmesh this goes surprisingly easy (it did not even do that when I first got the engine, and I have run it like that for well over 10 operating hours....)
I made a new gasket between lower end and tail gear unit, and I was surprised that I succeeded the first try (the edges around the large hole are less than 0.04 inch wide).

I did not touch the engine, as it was still running fairly well, I only cleaned the exhaust and stripped the paint of the flywheel.

I filled the tail with oil like I also did when running her, and was highly surprised that after 10 hours there was still not a single drop of oil visible on the outside, because none of the bushings has a seal of whatever kind. More so my surprise, that this oil had not even penetrated the gear cavity, because this was what I was counting on for gear lubrication when I was running it, but obviously the gears never received much for lubrication. Then I filled only the gear cavity, and it takes more than 24 hours before visible oil is leaking out.
I have to keep a better eye on lubricating the tail gears, but I have the feeling, when doing so this engine will still last some serious runtime with the proper care....

Brgds, Bert

Sure....

Fuji outboard driven airboat, has sprayrails this time. (2 min 47 sec)


But I have a small deep-V for it that I hope will allow the engine to rev higer and develop more power... I will place a pic of that hull as soon as I have found it somewhere on my harddrive....

You mean, you ran one back in the days?

Coz I have searched with all the keywords I could think of (which were actually not that many) but never managed to find even old digitalized footage of one of these Fujis running, let alone somebody running them more recently.

Not even mr "Rapmoz" (at least that is what he goes by on youtube), an engine collector in your neck of the woods specializing in marine engines (and owning at least a few of these Fujis, that I am sure of).....

Makes me feel quite unique

Ah, dang!

If I may ask: this type (originally air cooled and 1:1 drive) or the watercooled FW17RC with the flip-top over the flywheel and the reduction gear in the tail?

FWIW, I think it is awesome to see a vintage engine doing what it was designed to do, rather than sitting on a shelf somewhere

Thanks guys! And likewise, I enjoy it tremendously, seeing that little engine do its best....
Somehow LOTS more satisfying than a modern high performance boat....

I can't say "anybody could do that" because it is friggin hard to get max performance out of any engine, new or old, but tinkering with this old stuff is somehow on a completely different level.... Like a parallel universe
