I have two blowers with Homelite 25cc. On is just pumping out smoke so I'm taking it apart tomorrow.
I want to put it in a 1/5th scale clipped wing Cub. Maybe some floats too.
I want the electronic ignition. I have access to a lathe (a very accurate lathe! and CNC mill so just about anything I can draw can be made) so I may make my own hub.
I might have to put in a new ring. I've read av8tor talk about a special piston/pin/ring set.
Here are my questions.
Where do I get an electronic ignition. I saw one at my hobby shop today. for about $80? and about $165? for the one with the hub from CH. Are there better deals out there.

Should I get the upgraded rings/piston/pin setup and where are these found.

Should I use the Walbro 10?

What kind of magnet goes in the hub?

Would it be cheaper to buy a new Zenoah EI than upgrade one of these engines? I have a Saito 1.20 but I prefer gas.


Thanks in advance, Tim
