Quick timing question, Please Help!

If for some reason you can't move it far enough, then you will need to move the belt 1 tooth on the sprocket.

it moved quite a bit, but i think i finally got it now, it starts a lot easier, and runs smoother, i am gonna go for a drive now, and let you know how it is, but thanks to all for the help, i appreciate it, this is a great forum that helps everyone including dumb asses like me, lol.

well it gets up to speed a lot quicker, especially 0-40 is way faster, but it tops out at 68 mph, and i have to flog it thru third then hit forth quick to get there,  some of it may be due to no exhaust, its open from the downpipe, until next week when it goes to muffler shop, also i am running stock fuel. but, hey, thanks for the help!

hate to dig up this old thread, but i'm trying to set my timing with a guage in inches too.

Everything is fine right up until zeroing the guage. I zero the guage and then start going clockwise twoards tdc but way before i get there the big needle makes a complete turn clockwise(which would be more than double too muc right) then the needle starts moving counterclockwise before i hit tdc. Is this normal? should i just keep turning clockwise untill tdc then note the timing? It seems odd that the little movement it took from tdc to find the lowest part of the pump stroke was not very far. Yet when i zero it out it goes past .100 of an inch?

Nope, doesn't sound normal to me.

Are you sure you are starting at TDC for #1:

- crank at TDC: timing mark on the flywheel aligned with pointer
- cam at TDC for #1: both lobes of #1 up, cam locked with a locking plate
- pump at TDC for #1: pin locked in sprocket

From there its:

1) crankshaft counterclockwise 1/8 or a turn or so until the gauge stops moving
2) zero the gauge
3) crankshaft clockwise until exactly TDC and read the timing value 0.039" = 1.00mm

Here's some pictures that may help:

yup i lined up the flywheel and installed the lock pin in the pump gear. Didn't lock out the cam.

I had just put the timing belt on and set the timing with locking the cam,pump lining up marks about a month ago.

I thought i could bypass locking the cam as when i set the t belt all was good. When the flywheel marks are lined up the lock pin in the pump goes right in.

From starting at zero going back to tdc should it take this whole time for the dial guage to go to full advance?

I still can't see why it would make a complete turn around the clock.

I tried it many times to make sure i was at the lowest point on the pump stroke and it was. I can't see why the dial indicator would move COUNTER CLOCKWISE while turning the engine clockwise.

Hmmmmm..... strange.

It really sounds like you are one or more teeth out on the IP sprocket...  even with the pump fully advanced (pushed all the way towards the block) I'd be surprised if you would get more than 2 mm  (0.08ish ") during the clockwise rotation between the dead spot (where you zero the gauge) and TDC.

The usual advice here is to confirm your IP sprocket is in the right place... ie.. there's a key in the keyway on the IP shaft ??

[95gltd]

i don't think it can be a tooth off because

with the engine running you can push the pump all the way against the injectors and it clatters like crazy and if you back it off physically twoards the rad it retards it enough so it will hardly run. If you back it off untill it idles poorly then move it slightly twoards the injectors it runs fine. Smooth idle and when you pull the handle out it clatters a bit. Starts fine cold, good power.

If i was off a tooth on the pump i'd think it would be all the way either can't advance the pump enough or can't retard it enough. As i said previously when the flywheel marks are lined up the locking pin fits in place on the ip sprocket.

or else the dial indicator is junk. :?

Starting to sound possible... perhaps it's time to borrow a second gauge as a second opinion ??

The engine behaviour certainly sounds like you're in the right timing neighbourhood.
