timing revisited

[btoscano]

I am starting to wonder if the pump gear got off by a tooth somehow when i reinstalled the pump after the shop turned it up. I'm not sure how as there isn't much room for the gear to move. If the timing pin/"rod in injector hole by eye" view of TDC is accurate then 1. 65 mm timing is a bit below the original index mark on the timing case cover... I had the pump about 1/8" above that when I started. Either that or i'm doing something wrong!! turning up the fuel screws doesn't effect the timing, right?



I'll put everything back together soon and see how the engine runs.



I am starting to wonder a bit more... . when it was cold out sometimes the engine would go to start but cut off immediately... a second crank on the starter brought it to life... is that also a symptom of timing right up there the burning eyes light blue smoke??

The other thing I am wondering is if the pump timing hasn't changed (i. e. did not move one tooth when I put it back in) but now that its pushing more fuel the effects of the timing are more obivous? What do you all think?

There isn't enough room for the gear to 'move' a tooth. If you have not dropped the key, it can only go right. The indexed position is then the final setting.



The start and die then run with the next spin up is indicative of a minor air ingestion problem. All my trucks have done this on occassion but usually after sitting for several days.
