If it seized that's where you'll find the damage. You're looking for vertical streaks or scratches. If you find evidence one or both pistons seized you can use Muriatic (concrete etch) acid on a rag to clean off the aluminum on the cylinder walls. Be careful to only get it on the iron cylinder liner. You'll need to replace both pistons, too.

Also when taking off and landing, the MKIII variants feel wide and "planted," while the Firestar variants feel narrower, and a bit more teetery on their narrower gear. Landing my MKIII seems almost a no-brainer in taildragger terms, while the FSII is more classic taildragger, if you are not on your game, it is more likely to let you know it. A lot depends on if you like to haul "stuff" around with you when you fly. The one is narrow and ergonomically challenging if you like a lot of electronic bells and whistles, the other has lots more room, panel, and places for electronic junk to be mounted. I have equal access to a FSII with a Rotax 582 and a MKIII Classic with a Rotax 582, both handle similarly in the air, the FSII will fly the same speed as the MKIII at about 4-500 rpm less due to it's cleaner fuselage shape. Which works out to about 1 GPH less in fuel burn, and less in flight noise from the slower prop. But I fly the MKIII anyway, I just like it a bit better. Purely subjective.

It was one of those rare days when the wind was calm up high. A very nice flight indeed. The area is called Oregon Canyons. It starts in Nevada and comes some 45 or so miles into Oregon. The illegal's are fond of planting Pot farms there and it can get pretty exciting sometimes. The flight was 1.5 hours long and I burned 5 gallons of gas. I ran at mostly max cruise with very little climb most of the time trying to get up the mountain. Of course high density altitude and no little sink in a lot of places. I of course will have to go back a few times to get familiar with the area. It would be nice to find a spot to hunt Elk with my bow this fall, and that is all the excuse I will need to fly it.

If they read properly, when was the last time you balanced the carbs? Do you run separate air filters. I'm assuming K & N here, try cleaning and reoiling. Are you the original owner of the engine? If not, check that jets are the same, clip is in the same slot on the needle for both carbs. Last, look for air leaks in the carb boots. Take them off and look at the inside in a strong light. If you haven't changed them in a few years, do yourself a favor and order new from JBM. You could also have a crack in the rubber seal on the piston of a starting carburetor (erroneously called a choke).

The scoops go around a body so they spread out at the front. But it gives a nice area to put the oil cooler if I want one. Before I put the extension on the prop the distance between the back end of the scoop and the prop was about 1/2 inch, now it 4 inches! Not the best at sucking the air thru the tube, so it get hot fast.. If I don't get the temps down quickly, I'll buy normal scoops going all the way to the prop.. EXPERIMENTAL takes on a new meaning.. Fly safe.
