Side-effect of IP Timing
Last night I had my IP timed with an electric diesel timer.
It was reading 15 degrees when I started - only smoke visable at night under heavy acceleration - diecent power - some engine shake at idle Now its at 25.6 degrees - wont idle cold - slightly lower power then 15 but bairly noticeable - almost no shake - very very loud at idle and above 4000 RPM - ALOT of smoke. I have a mark where 15 was and a mark now so I'm going to play with it by hand and try around 20 degrees. I would think with the spec being 24 it should run better being 1.5 degree off rather then 9 but oh well.

No I did not. Simply rotated the pump.

You do know that the 24 degree spec is the drip meathod while the 15 degree spec is the electronic method? Don't confuse the two or mix them up.
they both effectly put you to the same spot. is that 25.6 point electrically measured? and did you tighten down the ip after you first checked...rotated and rechecked it the first time?

It's set at around 22 degrees now according to the numbers we came up with last night. The electronic unit used a pickup attached to the #1 injector line and sensed the pulse. It runs much much better now then it did at 25. I don't remember well what it was prior to the adjustments since I didn't drive it for 2 weeks prior to yesterday. I should considering how many miles I put on a year.
The sticker on my front crossmember says "Initial Injection - 24 degrees BTDC" Just as added info.

24º is only a number. It's used for static timing.
If you used a piezo electric dynamic/timing light system, the correct number is 11º or 15º or some such, BUT NOT 24º. Brian Carlton may know the correct number. If you used an electric RIV method, again the setting is NOT 24º, but when the lights do their on/off thing. Brian again: Specialized Indicator for IP Timing Edit: Beat by BHD by a minute. rats!!
