Seeking wisdom...from experience (someone else's)!
I'm currently running
40 pilot jets in the ol BS34's, and the pilot fuel-adjustment screws range from 3/4-1 3/8 turns out across the four. At those settings, the spark plugs are looking pretty good.
If returned to stock (
37.5 pilot jets), how many turns out
will that change, to achieve the same spark plug conditions?
