Not Ranked
Well cold weather is definitely limiting my test runs but what I have found is that I went from a size 70 idle jet to a 60 to make a drastic change in one direction or another as I thought I was running rich by smell.
The hesitation at speed was gone now but a rather large stumble when coming off of the idle circuit to the secondary’s.
I also found if I tried to go above 78 mph I was running out of fuel lol, but if I kicked in the secondary it was off to the races.
I have 65 idle jets on order and should be here this week and the experiment continues as it is definitely a learning curve.
