at least its been proven too many times that it doesn't matter how the fins are positioned the head will do its job. It just looks 'odd'.

Many years ago I had an MDS 3.5 cc aero diesel. It's head fins were like that from the factory. I regret trading it. Heavy, but powerful.

The prop wash spirals around the engine. Arguably the orientation of the fins as shown above is, if anything, better for cooling.

3.the new liner is flanged site on top of cylinder original flush ( davis head still perfect fit notice head sits on flange head not flush up about 2mm my other one is flush
4.Piston new one has a hole about 1/4 inch round below wrist pin, installed with this hole opposite exhaust, slot in cylinder perfect line up with exhaust outlet
5. porting slots were different in cylinder than one that was removed
6.this was a brand new setup in original pack from OS marked 10FP p/l

If you put up a picture of the liner I could compare it to my FP engines if that would be of any help.

And if the engine is cowled?

Nah, I think that if angled was best it would have adopted a long time ago.

Status: offline 		Tried a stunt Bob Davis suggested using a tubing cutter put a thin ring in the piston this of course raised the edge giving a tight fit in the cylinder, was putting in a second one and broke off a piece of the piston skirt gripping it was quite thin had a tape wrap and holding with a plier, too bad think it would have worked to restore compression martin

At least you now have a spare P/L for the 10FSR that you got awhile ago. Spares never seem to go to waste.

Status: offline 		Dennis quite true did not use my head on this one, the piston skirt was quite thin should have put in some plaster shoved in a piece of dowel, as a holder ,let it harden,with then cut the ring , put
in some boiling water to get rid of the plaster, clean, and would have been fine martin

Status: offline 		The Thundertiger GP .10 piston and liner will fit the OS .10 FP. I've done it. The TT liner has a thicker nickle plating than OS too.

I have done that on other engines and it doesn't last for long, only a run or two. After that you have a groove for the oil that could possibly help but I haven't see any difference from before.
