Default YS 170 BREAKING IN


Hi all I am in the proccess of breaking in a new YS170 CDI
I have run the engine with 20% Nitro and 20% LS oil for about 2liters at 2.5 turns on the needlle.
The engine starts first go and runs nicely at low rpm but when I advance the throtle it starts to misfire badly and stops.I have put the needle back to 2 turns but still misfiring.

Is this normal for new engine or is it still too rich.........YS recommends 2 turns however this sounds a bit too rich

Also can anyone recommend a place to buy a good spark plug for such engine...the one with engine is Chinese chicken s$&*(

THANK YOU IN ADVANCE FOR ANY ADVICE
