You did not answer the question if you spray starting fluid down the TB if it will run? If so I think you have a fuel delivery problem rather than an ignition problem. Crank the engine and just spray the starting fluid into the TB and let us know what happens. Will the engine start now but continue to run rough and backfire when you give it gas? This happened to me last year and it turned out to be a failing fuel pump.SnoopyDP wrote:Base timing should be 4 degrees BTDC. 454's do better with more advanced timing, mine is set to 9 degrees BTDC. You said you had spark and compression, if you spray starting fluid while cranking the engine will it try to start at all? If not I would suspect that your timing is off, did you change the timing chain yet? Were the gears metal or a plastic type material? There is a wire from the distributor that has to be disconnected to set the timing(I think it is tan). Did you use plug #1 or plug #5 to set the timing?
We have the front of the engine off so we can see the timing marks. We set rotor to #1 and we made sure #1 was on TDC both by compression and with probe in cyjinder.
Not sure I understand about one tooth off, because we put tenssion on the distributer but we can make minor adjustments while cranking the engine?
