Timing question

[fixkick]

so, true orig. carbs are near impossible to fix. unless just gasket bad.
great set of photos, and is dual advance, vac/mech,super !
it might be able to limit the vacuum effect.inside by using stops,? added?
or back off on base timing, try 0degrees the work up to 5. util it pings then back off
so glad to see the mech advance working,for you,, the parts drawings pretend they dont exist, HAH !

G13 engines are great. and ok, just don't mix heads, unless you do the CC chamber tests. for CR calculations..

ok that distrib, dizzy has its own, cmp pickup coil and its own ignitor, and work just like our 1989/90 G16s, same deal , only you have 2 vacuum nipples on the vacuum advance servo..

your doing good.
and crossing fingers or exit visa for you !!!
