I think u are playing the original engine. My suggestion is that
1) No need to do run-in for this original engine
2) Before u run the engine, remove the pull start and end plate
3) then use WD40 to clean the engine inside (just use WD40 to spray engine inside, let some metal dust to be flushed away by WD40)
4) Use air blower to evaporate all WD40
5) carefully reassembling your engine
6) go to run your engine and dont let the temperature of your engine over 100 degree
7) PLEASE BE RECOMMENDED THAT dont run-in your engine by idle-speed....LOW WIND SPEED, the engine can be eaily over heat
8) No need to use rich needle setting for running, its harmful to the chicken leg of your engine( Many people use this method to runin the engine, but actually no need...and they dont know its harmful to the chicken leg)
9) Just normally run your engine, and try to adjust the needle to feel the engine speed and sound(dont set the main needle less than 2 cycles)
10) Just consider the original engine as your test enginer for practicing adjustment of engine...
11) good luck
12) Use 20% or above nitro...
IF I am wrong, please correct |
