The subject motor followed me home today, so
now more detective work is needed.
It was suggested that the gas tank and magneto
are incorrect, and off of a Speeditwin.I doesn’t look like the gas tank mounts were altered, i.e.,
moved and rewelded, as the original decal is not burnt.
That said, I have no idea if the Speedster and Speeditwin
gas tanks were identical except the decals. Anyone know?Was a magneto an option with the 1930 Speedster, or
was there only battery ignition? Lots of 1929 Speedsters
on YouTube, all with battery ignition.Would the tiller handle I have be an Speedster or Speeditwin?
It has number 100143 cast on it. The reason I ask, there’s
a steel spacer on each side where the grab handle mounts
to the power head. Are those spacers a retro fit?Anyone have any digital data for this motor?
Many thanks, and more questions to come!

It turns out that the gas tank is the least of my problems with
this Elto. The project is going downhill faster than a Himalayian
bob sled team. I took the flywheel nut and cover plate off
and just about fainted. I thought the twelve bolts going thru
the flywheel were some sort of medieval crack repair, but
I think it was just "making the wrong parts work. Looks
like a ticking time bomb to me!The points cam with the twelve threaded holes looks factory,
but not sure for what motor. It doesn’t seem to fit on the
top of the crankshaft taper, but rather held to the crankshaft
with a allen screw or pin, that I can’t get out.That’s the biggest outboard condenser I’ve ever seen!
If anyone has any clues if the points cam is original I’d
be thrilled to know. If so, was if for a battery ignition
type magneto and flywheel?Not sure what it would take to get this ignition back to
original, or at least safe, do you?Guy I got it from today said he took it on trade. I don’t
think he ever worked on it, so I don’t know who to laugh at….
perhaps Rube Goldberg himself!

Might be the right tank, but with wrong decal.
The magneto doesn’t even look like its Evinrude. Looks more like Johnson to me.
All model 310’s would have been equipped with battery ignition from the factory. Model 311 would be electric-start. The 310 should have a cast iron flywheel with the typical Elto aluminum starter knob on it.
The tiller handle you have is correct, its the short version. There is a longer tiller handle that was also available. no spacers per se, just one friction washer (part # 170114)
I have a service manual with parts list that I can scan, but I’m busy for the next few days, so won’t get to it until Monday most likely.
Don’t worry too much about the timing, you just have to position the pistons at TDC and set the cam so the points are just starting to move, and you should be in the ballpark at least. But would be better if you either acquire the original flywheel and timer, or else convert it to an Evinrude magneto, but at the moment I can’t exactly say which Evinrude magneto you’d even be looking for. Probably one for a Speeditwin would work, depending on your crankshaft taper. I bet what has happened is that somebody cut the hub out of one flywheel and grafted it to a different make altogether.
Hope this helps eh
Best,
