Hi Hector,
thanks for your reply, you have made some very good points, i was planning on putting the engine in the model (also a TF FW190) and flying but i think i will carry on running in for a bit longer.
i have run about 2.5 litres though the engine now and although it starts and runs well there is a flat spot in the mid range where cylinders are obviously dropping and the engine vibrates quite a lot, a bit more than i would like to see in flight in the airframe.
would you recommend roatating the engine on the bench and running 2 tanks at rich setting to bed each cylinder? i think i read before your theory on this, also can you give me a rough max temp of the no 1 cylinder at its max lean point (safest running temp), i have a laser heat gun and a single high temp sensor on my telemetry, i understand you have probably gone over all this a thousand times so im sorry, im at work at the moment so cannot read though the whole radial thread, i will do later on.
thanks for your help
Joe
