ok. since i bought my p-38, and all of the r/c related threads lately, i went and started prepping my r/c air force for service in a few weeks. i may have run into a couple snags though.
my twinstar hasn't been up in about 3 years, and my world models t-34 hasn't been up in about 2 years. the twinstar has a pair of os .25FX's. the t-34 has an os .50SX.
i love my os engines. the problem i ran into though, is that although i thought i "pickled" them properly(i was told that putting a few drops of mobil1 down the carb, spin the engine by hand, then cover the carb. inlet), the 25's not only are very difficult to turn by hand, but the barrel in the carb is stuck shut.
the 50 in the t34 was very tight, but freed up pretty quickly....but it feels very rough, as if the bearings are gone. this engine probably only has about 20 hours of flight time on it, as i installed it new in this plane. the 25's in the twinstar, probably only about 8 to 10 hours, since a rebuild before installing them in that plane.
so........as i don't know much about these engines......what am i looking at for repairs, if any? as in will it be worth repairing them, or more cost efficient to simply replace em?
on the good side, the 1.20 in my icepoint seems perfect(although i'm more than likely gonna sell that plane rather than fly it), the os .91FX in my world models extra 300 is perfect, the os.50SX in my hangar 9 t34 is perfect, the os.50SXH in my raptor is perfect, and the ys(i think) 1.5 4 stroke in my p51 is perfect.
can yas tell that i'm tryin to rush the summer to friggin get here FAST?

thanks guys!!
