Timing Mechanism Failure?
Ok, so here's the deal. We took the IP out to tweak it for more fuel delivery. Put it back into car, engine at 24* BTDC, IP at timing marks. Have the right drips/fuel delivery from fuel pump. Car runs like crap, shakes, smokes, backfires. We take it out thinking we had the timing off 180*. NOPE. Since then, IP #1 has been sent off to experts and needs new delivery valves and plungers. No big deal, we install IP #2.
Now #2 CAN'T be timed, fuel dumps out on the exhaust stroke at 80* BTDC at 24* ATDC, pretty much constantly. Ok, we assume that IP #2, which came from a non-running WVO car has issues. Go to junk yard and buy IP #3. It's dirty, but supposedly came off a running car. This one does pretty much the same thing, has fuel at 80* BTDC, stops delivering fuel from 18*BTDC to about 10* ATDC, then continues to dump fuel through the exhaust stroke as well. Now I'm thinking something must be broken in the timing mechanism. Any thoughts? Have I got 3 broken IPs or did I break the *(#$$@# car? I'm dying here, oh and we have a race in 11 days. ![]()
