Hi Scott

I would remove all the plug caps and clean them with brake cleaner and compressed air to remove any grease.

I would trim 10mm off each lead before you screw the plug cap back on.

Have you checked the pick up gaps.

Have you checked the fuel level in the float bowl/ needle valve, i know you've rebuilt the carbs.

Thought I would let everyone know how my story came out. After messing with it for quite a long time I finally gave up and took it to a rotax repair expert. I was swore to secrecy, however I can tell you at least in my case he replaced a set of floats, the diaphragm springs, bumped the idle jet from the stock 35 to a 45 and adjusted the air/fuel in from 1 and 1/2 to a 1/4. It runs perfect now. Basically he balanced and blueprinted my carbs, and did the initial dial in which in my case I don't believe had ever been done. FWIW.

Jim Scott/Aircore Aviation Arlington, Wa. One of the nicest guys I've ever met. I just wish he lived closer, but at least he's in the same state :)
