Now the carb is jetted 71 in primary and 78 in secondary, and as far as I can tell, the little engine liked the leaner condition it's now under. Low speed is at about 13.5-14:1 I would say (engine warmed up) and goes in to 15:1 at cruise to about 2300rpm, where it then drops to high 13:s.
Have thou, since the down jetting, got a little problem with the car stumbeling some on take off in low speed, wich was'nt there (or as evident) before. Tried changing pump cam on primary, wich made it better, but still there (went from pink to white, both in pos. 1, as this would give more initial lift from what I read).
Have a little concern that the quite big carb on this mild motor with lazy gearing gives me a harder time due to me cruising with the blades barley craked open, wich gives a very large amount of increase in airflow when i get in to the gaspedal. If i ease in to it, or cruise in first gear at lower speeds (even thou both second and third could easily pull at those speeds) the problem goes away, or eases of anyway.
