what my dad does to produce great running glow engines and this has been proven with both my OS and TT 46 stock class pylon engines is, from out of the box engine he strips it done totally and inspects all ports for and burr dags etc etc , he then laps in the piston to linner nip using heaps of wd-40 lube and also he laps the liner to case so it fits in easy . he claims this pre run method seats the piston in alot better than it would just running in etc also the liner to case lap assists in a better heat transfere around the liner . the engine starts its run in on a full synthetic oil mixed at 20 % and no nitro, the run in consists of a simular heat cycling method of 5 minutes running rich then 15 minutes cool down and so on until 40 minutes of running has completed, he then strips down the engine / inspects and cleans all internals ready for racing with castor based oil mix. i must say these engines run very well and do have the edge on other simular engines in this class.
