Also how much was it?

I think everyone got different things out of the class. I found it useful because it covered things not normally covered in Rotax school, not to mention it was required and I have to have it. It is $300. I am going back in two weeks to do the Heavy maint class that I need. You need the heavy class if you are going to rebuild carbs or work on gearboxes. FAA and Rotax are starting to enforce the rules. I would not be an A&P and do a Rotax engine any more if I didn't have the school or the update to be current. -------- Roger Lee Tucson, Az.

From: "wildirishtime" Well, I installed some new fuel line cause my old black rubber was getting 'old'. Engine was dialed in PERFECTLY before this. Must have dislodged some crap in the process..... Now, one cylinder at idle generates almost no reading on my EGT yet the other cylinder is at 900 to 1000 at idle. I immediately shut down and found wet spark plugs in that one cylinder only. After drying the plugs I checked again at 4000rpm, and everything runs pretty well, so it looks like it's 'idle' issues. (and no, mag check had no effect.) So, I did the obvious: I pulled all the jets and checked them for junk. Found a little bit of junk, cleaned it good and carefully, and replaced all the jets back in the carb. Even pulled the mixture needle and checked it plus the float valve, got em all clean, but STILL SAME SYMPTOMS! What have I missed? What spot are "out of sight" that are hard to clean that would create this scenario? Any hidden orifice or pathway? And of course, the obvious question, how do I clean it out safely and get back to running?

Have you thought about a sticking valve? And is the spark getting to that cylinder ?

From: "wildirishtime" Well do you mean 'float valve'? Remember, the engine was running perfect just the day prior to my swapping out the rubber hoses - it's about 99% sure and obstruction in my book.
