HELP...Will not idle in gear

What was the timing set at, and how far out were the mixture screws for the last 2yrs.?
Put 'em back,if it won't run, somethin's wrong. May or may not be related to the parts swap.
Unlucky coincidence, it happens, but first you need to get back to -0- and figure it out from
there. As pish says,a little carb cleaning action may be called for, or maybe you've got the
timing too jacked up to jive w/your idle mixture. Maybe go back to the orig. dizzy if they
didn't send it back already.And I've seen aftermarket boxes run,but run terrible,so..........
