Yes, that is the mechanical or centrifugal advance. This is why it's best to set your timing at 4000+rpm so that you get the correct total ignition timing.

But you can also lock the dizzy. The easiest way would be to remove the springs from the advance mechanism. That way the weights swing out to full advance as soon as you start the engine. Another and more fool-proof way is to tack weld or jam the weights into the full advance postition.

To gain acces to the springs and weights you need to remove the lobed gear from the dizzy shaft with a puller as well as the plate that holds the magnetic pickups.

I've done this mod to a spare dizzy I had and it's really easy to do. Good luck.

 

hey thanks a lot, thats what i thought was the problem. It doesnt sound that hard to lock that up, i will fix it pretty soon. thanks.

Can you make this thread a sticky?

I fixed my site a little and upped some new ignition pics. I also decided to start calling my poorman's direct fire ignition system SLIDFIS because it uses a single leading ignitor and is still a direct fire ignition system (it's only one new letter to remember compared with DLIDFIS). All the old posts refering to poorman.html and pmdfis are now linked to slidfis.html at my site.

I'm doing lots of cool things this summer, but the pics always seem to be the last things to show up on the web page, so check back now and then.

 

The rotors r 90 degrees from each other on 2 rotor engines
120 degrees from each other on 3 rotor engines.

 

Nope, they're actually 180* apart on a two rotor.
