Just a little info. on my 3250's. Reading and rereading sooooo many posts on these engines, I still bought one cause I ain't never had any kind of engine I couldn't tune! Uh-Oh! Carb kickin my butt! Since I was going to run it inverted I wanted an easy starter, like my 4 os's. So bought the os7d carb, and like magic, engine ran good. This engine is on a Sig Rascal 110 f.y.i., starting still tempermental, so turned engine right side up. Took out flying and engine died prematurely. Hard landing broke landing gear, so only got two flights in that day. As doing a repair to the plane, put engine on test stand to retune, could not get it to start. Pulled head and I feel like it showed signs of getting scored. Spits, but it will not start. Sent in for repair. [warranty, I hope] Okay in mean time, got big ole plane, no motor, so maybe I order gas motor. After looking at the two bisson mufflers and other tiger stuff I have on hand, couldn't write off ST's just yet. So, I let my two sons know they were buying me a new engine for Christmas, yippee!!Two day shipping got motor yesterday. Put on my bisson muffler with one port plugged and installed original new tiger carb. Install my 18x8 topflite prop and got w.o.t. to tach about 8300 r.p.m., but midrange sloppy, just like my other engine was with same carb. I installed a 20x8 prop I had on hand, and wow! Totally different engine!!Readjusted the high and low needles, now w.o.t. is 6600r.p.m., but transition from idle of 2300r.p.m. to 6600 is flawless!!It seems like this big engine needed more of a prop load on it to use the fuel. Once back on plane and in the air, I may regret my engine choice, but after running 1 1/2 gallons on test stand, I am a happy camper. I'll update my story when I get back in the air.
