Ok I'll have to send some running videos then...
@ dirtyoldman00
hm actually no not really, my fuel mix is essentially the same.
when I first ran the engine it was with regular lawn mower ashless oil non synthetic at 30-1 and remember it was very rich on the low as well as the high needle. That contributed to the fouled plug.. After breaking-in I swiched up to klotz synthetic and kept it at 30-1 for a bit.. then mixed it down to 32-1 eventually. All this was on the original plug.. Then I came in here and asked, at that time I leaned out both needles and richened the high speed needle about 1/8th to a 1/4 turn with a hand held tach to check speeds.
I've sice got a onboard mini tach to check so ill re-tune with that and report back with some videos also.
It's misfiring very infrequently now so the last mods I think I'll need to do is check that spacing on the plug and check the timing.
Thanks guys, it's getting there, I think.
