I have found if a magneto is suspect it is far easier to change coil, condenser and points all at the same time. A more expensive way to solve problem but it does mean everything is new and should give years of trouble free running. Also only requires setting timing once.

Alternatively the throttle cable needs adjusting at top of carb, if too long it allows slide to drop to far and engine will stop. Adjusting length has same effect as opening throttle with lever ie it lifts the slide and needle.

The block looks like a Mk20 or 25 but the fan cowling is wrong for either of those. The cowling is similar to that on some early Allen Scythe engines. A mystery. Any part numbers on the castings eg block, magneto back plate etc.?
