Help! My car is worse! It's still backfiring out the tail pipes and really missing bad. I try to set the initial timing at 18deg. but it won't even run at that. It's still running extremely rich. When I turn the distributor to around 25 deg advanced at idle it runs better for a second and then starts to stumble. I can't get it to idle at all! If I pull it up to 1500rpm is runs good for a second and then starts to miss and stumble. I checked the following:
-Put the timing light on each wire and check to ensure each were firing and they are
-Check the cap and rotor
-tried a different coil
-Tried a different ECU
-Pulled carb and ensured everything was set properly for base line. (Transfer slots etc...)
-Check the rockers arms and all seem tight on driver side so I assumed passenger side is good
-Plugs are carboned up pretty bad but not wet. the #8 was a bit wet but I wiped it off and it was just carboned up after that.

I have a show tomorrow and really want to get it running.

Any help is appreaciated!



What kind of plugs? If they are Champions and they are black....they are junk!I would screw a set of NEW plugs in it and start over.
