The UL II-02 had a probable seizure on the #1 (PTO side) cylinder. Examining the piston and cast iron liner its amazing how the piston top by the exhaust port had melted and eroded and that whole exhaust port side of the piston just lost its metal onto the liner wall making one hell of a mess. The rings were intact but frozen in that side of the piston. I was trying to dtermine if I could hone the liner smooth again, but it just looks like an awefull mess and I think I better replace the liner. Anyone know how to remove a cylinder liner from a Cuyuna UL II-02? When replacing Pistons, is that normally done in pairs or can I do just the seized one?

It was designed to protrude the same as the front spar carry through.. The tube dia was such that the square wing fold hinge fitting would slide on and then could be held with a pin of the same type that holds the wheels to the axle.. bolt, pin etc.. This dropped the wing enough to fit into my garage..

Here's the deal, guys. I have a Challenger II Clip Wing in the hangar that I'm supposed to fly to PA next week. I have absolutely no experience with the Hirth and the thing is unsettling to say the least. I could not, in the hour I've flown it so far, keep the CHT and EGT alarms on the Stratomaster from going off. The CHT alarm is set for 500 degrees and the EGT at 1300. Yep, you read those numbers right. I took it around the pattern three times before a short cross country flight. During those, I could keep the CHT's under 400 in climb, and they came right back down when I cut throttle at the threshold on down wind. After I completed the roll out they were back down to 250 or so. When I flew over to my friend George's house, about 15 miles away, the CHT's were running 512 and 549 and the EGT's were 1225 and 1252 by the time I over flew the pattern back here at home. The engine will not hold a throttle setting. The owner had attributed this to throttle linkage that wouldn't hold, but I kept my thumb on it the entire flight and I know the throttle did not move, at least on my end of the linkage. It never throttled up, once a setting was made the RPM would not climb uncommanded, but it would bog down several hundred RPM with my thumb holding the throttle in place. A tap on the throttle would bring it back up, but then in a few minutes it would bog again. A couple of times I would have sworn it was going to sieze, but it responded to the throttle and came back up to nice smooth running again. I've got a feeling this POS is going to PA by trailer at this point. Did I mention I had the stick almost full forward the entire flight? I'm only 20 pound lighter than the owner and I would swear I had all 20 pounds pushing forward on the stick the whole time in the air. After today, I really LOVE my Kolb and Rotax.

Hi Russ, i think that is pushing the envelope of my computer skills but I will try. Planning to run the engine tomorrow if the promised weather window materialises. I think that is pushing things as we have had a reasonable day today which enabled me to get the plane here on an open trailer and the way the weather is at the moment two consecutive days without pouring rain is too much to expect. You may know that a large swath of the middle of England is under floodwater. thousands of homes are flooded with people sleeping in schools, council buildings etc. Thousands are without drinking water. Millions of litres of water have been distributed and there are bowsers on many city streets. It is going to be months before some of the houses can be reoccupied. More heavy rain for my area is forecastr for Sunday. Greece and Italy are having fires ignited by a ferocious heat wave and people are dying of heatstroke and dehydration. My brother in law was in Gambia in May and the village he stayed in is now under 4 ft of water from torrential rain.The weather seems to be cocked up everywhere. Heaven help a sailor on a night like this.
