Re: Interesting timing problems... ideas

" So, I resurrected my 73 Commando 304/3spd.

" So I towed it home, rebuilt the carb and it started

" ran better, but backfired like crazy.  So, I restabbed
" the dist and tried to set the timing (advance
" plugged).  SO I can get it to idle really well, where
" it will rev with almost no backfiring.  But at that
" point the timing is so advanced it will hardly turn
" over when I go to restart it.  If I get it to where it
" will start, it will backfire (mostly exhaust) like
" crazy.  
" 
"  Attempting to set the timing with a light is
" WAAAAAAYY off.  When the engine runs decent, the
" timing mark is still about 25 degrees clockwise from 5
" degrees BTDC.  If I even attempt to get it close, the
" engine almost cranks backwards!  

can you tell if the vac advance is working?  just a thought, but 25
deg is just about where timing should be under idle vacuum.

from sitting that long, the dist advance mechanisms in general could
be seized.
