yes please. EDIT & when you're done, slow the idle a bit & see if it stays at 18, we need to b sure we're not into the mech curve (slots) at 800 idle
Its practically guarenteed to be into the mechanical advance. Even if by chance it is 18 at 800, it will change then when going into gear from neutral. There's no way around that. The advance plate has 30 degrees in it. By setting full timng to be 35 at 2500 or 3000 rpm, base timing will be 5 degree. If the springs are just right, the timing will advance 13 degree to be 18 at 800rpm. Shift into gear, rpm drops, and timing drops. This makes tuning in gear idle fuel/air mix a PIA at best.
Direct Connection (a) liked the easy start which comes with using this tpe of approach - advance at starter speeds is 5-10 degrees. (b) didn't care too much about good idle (c) used that super heavy long loop that almost stopped advance by itself so the overall slot length wasn't that important.
