Ahhh! Could you fellas please explain for my limited experience, exactly what Four Stroking is.... and what it sounds like. Also why it's somewhat Normal for these engines.
Example: Today I've messed with my clip position. Leave it in second slot is best for low and high end, however I take off, run up rpm's and hit a place where the engine stutters a little then it climbs through it and rev's higher & hits a minor sputter again till it runs flat out, sometimes rev'in higher sometimes not quite so high.
66cc, NGKB6HS plug, stock everything, on 3rd gallon of fuel running 24:1mix with Bel Ray H1R Synthetic oil.
Am I 4 stroking when it's sputtering? What is causing it. Was thinking of messing with main jet sizes.
Please explain, I have my ear to the computer.....Ha Ha
Thanks in advance,
