Since my engine out, I've been trying to get back into the air. It's frustrating because I've done everything I was told I needed to do. I bought a new piston and had a certified Rotax mechanic install it. He honed the cylinder and put it back together and it ran great. Then, during the hour long break-in, it started running rough. Now we tore into the engine again, only to find that the cylinder wall is scuffed!! mailto:!@#$ This simply means enough wasn't taken off of the surface of the cylinder the first time. It would have helped if he'd checked the diameter after honing it!
Not only that, but I found out a red-dot piston was used where it was originally a green-dot piston. Both service centers I spoke with said that was a bad idea. Now I have to have my cylinder sleeved for around $250 and buy another $200 piston. If I can find a green-dot piston that is easy. If not, I will have to replace the other piston with a red-dot, then probably have that cylinder honed as well....
This is getting old for two reasons. One, I need to fly!! I'm not a nice person to be around when I'm grounded. The second reason is that I bought a 2-seater so I could take up passengers. Even after I get it running right, it will be a long time before I'm comfortable taking up passengers again.
What a crock of mailto:!@#$ this has turned into!

Never worked on a Rotax but as a retired ASE certified master automotive technician I can't imagine a mechanic who would forget to mic the cylinder after honing. That's just plain inexcusable! He deserves to have his certification yanked or, at the very least, offer to pay to have the job done properly.
Carole and Drake say...
Great pics -- our favorite is the one of the PPC with the sunset, IMG_5655[1].
You obviously spend a lot of time getting the right settings and backdrops for the PPC pics!
Thanks Carole and Drake!
I try. I spend a lot of time flying around my friends trying to get the sun just right. Sometimes it pays off!
Rocket Man - I agree, I learned the hard way. I finally did it right and pulled the cylinders off and sent them in to be bored and honed. When I get them back, I will also get new pistons, so hopefully no more issues. I need to fly!!
