3 further tanks - rich, running a circuit with full gas
Q. I've gone through quarter of a gallon, at idle slightly high tickover which slightly drops, after 10 seconds punches of the line clean plenty of smoke, maybe a slight hesitation/bog... Flat out sounds good, reving high slight trail of smoke - all seems good but the engine temps are way down 65c/165f which leads me to believe something's way out with the tuning?
Fook - had a look at it tonight, LSN was <5 turns out and the top was in from flush.. So the old newbie, too lean on top fat on the bottom mistake. The clue came from Cody kings tuning vid where he talks of the revs not laying down.
Hopefully the bottom being so rich compensated for the top and not done too much damage(there was still a trail of smoke on top.
Reset to factory and will take it to the track tomorrow and keep the needle increments steady.
Venturi was 6.5 up'd to 7.
