Jpaz,So I have been tweaking carb settings and getting my engine running really well. I was going over the build sheet for my carb and found out that my jets were 12 sizes apart! Was set up with 68’s in the front and 80’s in the rear. I always thought that they should be more like 8 sizes apart with a power valve in the front only. So I replaced the primary jets with 72’s and left the 80’s in the secondaries. Engine responded very well. It had a slight hesitation and now it’s gone. I still need to check the plugs, but I’m very happy with how it ran yesterday.
You must have a great tune, as you have the same primary and secondary jetting as myself lol.
