Re: [Amc-list] no guts in the 287

I once had a '57 Chevy with a high-mile 283 in it with exactly these
symptoms.  Turned out to be the timing chain had jumped only one cog on
the cam gear, and stayed there.  I guess one cog is enough to get the
valve timing hosed up enough to have no guts, but still idle somewhat
OK.

Later on I had another car come into my shop (a Pontiac Lemans) with
these same symptoms -- turned out to be the same thing once again (junk
nylon-covered gears!!).

well, i have found that the timing advance is shot. i am not positive
however if that is the cause of all my problem. im doubting it. it idles
fine, and in neutral or park, it rev's just fine. put it in gear, it
still idles, but you try to give it any throttle, and it wont pick up
rpm's. you keep giving it more throttle, it will bog down and barely run
and occasionally die.
i know the timing has a little to do with it. if i twist the dist. cap a
little while giving it throttle off the carb, idle does pick up a
little. this with the park brake on and front wheels chocked. rear
wheels off the ground. when i take the park brake off, the wheels spin
fine. shifts thru all gears just fine.
tells me it should not be the trans. anyone have any clues?
