My timing experience

Well on Friday I received my Snap-on/Blue Point timing tool kit and today (Sunday) I decided to go for it. Wow what a pain. It wasn't all that hard except for the fact that the pump kept going all over the place when I would pull the gear or when I was tightening the nut. I would even break it loose and then tighten it very little, get it in place, and pull it again and it would still move around real easy. My timing from the factory was about 13. 25 so not too bad. I knew it had to be close because I get good mileage (19-20+). Well I was aiming for 15. 5º (5. 5mm) but settled for 15º (5. 4mm) because I finally got it that close and I was about to go nuts so I left it for now. It took me 5 hours, which includes sitting there at the desk thinking, and taking breaks from the crazy thing to cool off my head. I don't know how many times it took me to get it right. I hope the next two I have to work on will go better then this. If anyone has any bright ideas as to how on earth to better keep the pump from moving when pulling the gear then please share them with me. I sure hope the thing doesn't slip now. I hosed it down good with break clean and air-dried it. I then torqued the nut to 160 rather then 144 as called for.



I found TDC by adjusting the no. 1 intake valve down 5 turns when the engine was coming up on TDC, marking it, then backing the valve off and rolling the engine past TDC and doing the same on the other side. I then measured between the two and marked that. I used the tack sensor as my reference point. It worked real well because after finding TDC this way I was able to push the timing pin right in with no trouble at all which told me I was right on. Maybe by next Sunday I will be up to tackling another one. :eek:

Mark,

Do you have the number for the tool handy? I am going to get one to set my timing and was wondering what number it was.

I hope my experience with setting the timing goes alittle smoother than yours did. I will let you know.

Thanks

Chuck, the timing kit is part number SP500 from Snap-On. I hope you have a better time at it then I did also. Good luck.

I have not driven it much yet but so far I have not noticed much difference. It seems to run down the road with less effort just cursing but then again it's one of those things where it might just be in my head because I worked on it. It sounds pretty much the same to me also. Some seem to think that they "cackle" more when advancing the timing, which may be true if you went way up but 15º seems to make no difference. Of course time will tell on mileage. This is where it will probably make the most difference.

Well, I'm at 16. 5° and it does cackle more at idle... . but only when it's about 30°F outside on a cold start.



The power from timing will probably come once you all start to really pour the fuel to 'em... ... so far I love the advanced timing. No more high-rpm popping.
