As a matter of record for other people reading this . . . .

The Homelite 45 with electronic ignition should be easy enough to hand start.

A friend uses a Hobbico 90 with two gell cell batteries wired for 24v to start his Saito 220 glow engine though I doubt the longevity of the starter?

I tried the same Saito 220 with my Sullivan Dynatron and a garden tractor 12v battery and I thought the Dynatron did very well.
