RE: Motor Timing Question

Thanks for the insight Bluejets! One more question and I promise to put this to rest. Does anyone know if the coil assembly contains a transistor or capacitor to help time the spark??

RE: Motor Timing Question

Thanks for the input!

I'm fairly happy with the motor so far and I think it will work. I wish I was more mechanically inclined to cut away some of the 'dead weight' on the motor like

RE: Motor Timing Question

Seems the motor plateaus at about 6,000 rpm. I'm using an 18x6 prop for just testing on the bench. Maybe a smaller prop would bring the rpms up some.

I just want a nice easy flying "Sunday"...

Motor Timing Question

Hello:

I haven't been able to find a good explanation of the way a simple 2-stroke motor with flywheel and coil (I have a Poulan 25cc off a craftsman weedwacker)
handles timing as the motor...

Woohoo! Quick test run of my Poulan 25CC weedwacker motor after putting it aside for a year. Couldn't believe it worked. Now to find an old plane to

RE: 25cc Homelite short-shaft

Ozpulse Where did you get the 'hollowed out" prop nut?? Or did you fabricate it yourself? I could something like that for my

RE: Craftsman 25cc Conversion

Neat! I wish I had the same knack for fabrication. I guess I'll be stuck with the stock muffler until I can find a replacement.

RE: Craftsman 25cc Conversion

Wow, those are nice motors! Thanks for the input.

Did you fabricate the mufflers yourself? I'm having a problem finding a source for aftermarket mufflers similar
to the ones you have.

RE: Craftsman 25cc Conversion

Yes...I was wondering if the fins are shaped to "scoop" the air in the direction of travel, which would seem to make sense. In that case the motor would seem to rotate counterclockwise. I attached a...

RE: Craftsman 25cc Conversion

Good point! Sorry for my ignorance here, but how do I check the rotation direction? Is this a physical rotation issue or a timing issue?
