I have been reading a lot of threads about timing issues. My problem is the error message on the timing graph. It reads "Timing is too advanced to be plotted!" I tried to retard the timing by moving the pump toward the radiator. When I do, the engine smokes, stumbles and stalls. I went back and checked mechanical timing. Cam and IP were right on. The flywheel was off a tooth(ring gear vs TDC mark, not TB tooth). Reinstalled it and it is now dead on. Started it and it still has the same problem. What's next? any ideas? I read that some are moving the IP belt a tooth. Is that ok for the 1Z? Please help. Thanks
