I am currently running Mugello 186, Varitronic ignition set at 19 degrees, dellorto 26 carb, main 104, pilot 48, atomiser av266, needle x7 second clip, slide 40, choke 70, Ancillote exhaust.
If you are still with me the problem is :- (1) starting from cold, it may start on first kick or takes ages despite changing spark plug, once it does start for the remainder of the day it always starts. :- (2) when on 1/8 to 1/4 throttle it runs like a pig whether stationary or under normal drive conditions. (Four stroking ? ) Otherwise performance is excellent pulling well both one and two up.
I have read camlam suggested carb settings, but which do you suggest I change first, and regarding the various jets do I need jets with higher or lower numbers.
P.s. The choke is working fine and I follow the recommended throttle positions when starting.
Thanks in advance
