Howdy All,
I just got off of the phone with the Wildfire dealer in Winnipeg. (Yes, we are still in the midst of a snow storm). He said that the 185 engines on the Wildfire Mark 3 pumps are not the same as the older 185 engines from Rotax. He asked me to bring in my pistons, etc so we can check the size of teh rings and seals but he isn't confident they are all interchangeable. One certain difference is port size.
He's also familiar with the Lazair, having build one or restored one several years ago.
Anyway, I'm going to go in on Friday at lunch, they are just down the road from where I work.
Here's hoping that Tyler is safe on the road or safely at his destination.
