I’m going to look at a couple motors, and I’m not really good on identifying – Can anyone give a positive ID on these 2?
This should be easy for you guys – I’ll be surprised if it takes 5 min :~)The first I think, maybe pre war Johnson or Evinrude? But maybe not …….
The 2nd one also looks familiar, but again, I’m not sure –
Bingo! And here it is in the 1934 catalog :
Thank you all – Now I just have to see them in person :~)
So, would this motor NOT have had a lower cowling and plug cover?
I’ve seen a photo of a Comet, with cowl and spark plug cover :
VS. This, without either, and so would be complete, as is :
I’m trying to understand what I’m going to look at……..
KB1 Special and KB1 A Standard were same except upgrade from
poppet valve fuel mixer to carburetor. KB1 was dropped from
line and KB1 A changed to a steel gas tank to conserve aluminum
restrictions imposed by government. The KB3 Deluxe model
had a distinctive “chin” tank, cowl, rewind starter and spark plug covers.
Due to possible parts swaps identification is tentative, however, the
tank is almost certainly the non rewind tank used on KB1 and
early KB1 A
Edit
ID tag on prewar singles is on Port side of leg, while ID tag on postwar
singles is on Starboard side. The motor in second photo has ID tad
on Starboard (post war) side. It would appear that leg and clamp
assembly are from a postwar single. If so,clever native craftsmen have
been at work.
In your photo of a restored KB1 A the AJ3 carburetor has a rectangular
lump of excess metal. Apparently, initial production of AJ series had this lump.
Motor in second photo may be a parts motor with parts from here and there. The ID tag may not give the whole story as power head assembly and leg may not have left the factory together. A little
detective work is in order.
Edit
If as I suspect, motor #2 proves to be a collection of parts, what then?
Tough call unless price is right. Those with experience and parts can get things mostly correct with a reasonable investment in time, money and frustration. I would jump on it at $10 and pass at $100
…somewhere between I would flip a coin If you go for it post
better photos here. I would like to know how far off my guesses are.
