I have had this little engine for a long time and thought it is about time I got it going.
As you will see it is an inverted two stroke with battery and coil ignition.
I believe they are not rare, but not common either.
There are very few in NZ and I know of only one other here. Are there any in the UK?.
This one is in good condition and still has compression.
Merv.

That reminds me of a little engine that was in SEM back in 2009?

Is it a re-badged Elgin?

*EDIT can see "Elgin" on the transfer now.... must have been a long day*

Thanks Peter for the picks.
Both of those look like they were for sale.
I am getting some help from a guy in California which has given me a better idea of how it works. He tells me they are quite rare.
Still wondering if there are any in the UK.
Merv,

Pretty sure there are one or two in UK, probably just not owned by forum members.

I didn't realize how long ago I started this thread. Over the intervening years I have had several attempts to get this thing to run, with no success I could to get it to fire up but it wouldn't keep going.

It turned out the priming pump wasn't working very well. It was a one piece diaphragm type with an inbuilt check valve immersed in the fuel tank. the priming pump was leaking and the check valve wasn't working. It couldn't be repaired and I had to take it apart to see how it worked. the spring had rusted out so the ball wouldn't seat properly.
making a new pump was going to be a delicate and tricky job. I made the new diaphragm from brass shim by forming the two halves and soldering them together along with the plunger rod and the the check valve. the diaphragm acts like a clicker pulsing down on the check valve and pushing the fuel up into the carburetor. when the engine is running the suction lifts the fuel through the check valve. all very simple.

Yesterday I had another go at it. I had thought there must have an air leak so I took the engine apart. there were several places where there could be a potential air leak but everything was in good condition and no sign of an issue.

On assembly the engine started and again but wouldn't keep going. I found that keeping it primed it would. Then it struck me! There wasn't enough carburetor vacuum to lift the fuel. This was rectified by stretching the spring under the flutter valve.

After some adjustment with the needle valve I got running pretty good. It is governed by a counter weight in the flywheel shutting off the spark causing it to miss. It sounds rough but that is how they are. With a load it is more consistent.

All I have to do now is to set mount the battery and coil and find something to load it with.

I can see an article for the SEM coming up.

Perseverance pays off in the end

It does sound better once it's loaded.
