Some day someone will tell my why an annular booster in anything except a dominator is a good thing. I’ve never seen it work.
I guess today is that day.
In 1990 I had Norm at CFS build me a ported 4781 850DP and replace the boosters with annulars.
It’s been a fantastic working carb for 30 years.
I’m sure there are better carbs available nowadays, but that’s always been the 4150 to beat for me.
