Will not go past 2200rpm, popping and white smoke..
 

Might my timing have slipped... is that retarded or too advanced ?

Sounds like its way advanced

are you sure? how will retarded timing act like ?

Most of the time if it advances it wont rev up hardly and pop and smoke. If it was retarded it would start super quick, have instant throttle response and no top end power.

well, truck starts up fine....

i have not yet connected the turbos since i was going to break in the clutch properly without them and have my AFC foot all the way back...

thought this was maybe boost related but it doesn't seem to matter...

maybe 20° timing is too advanced ? at what timing would it start acting like this ?

i'm also thinking that it should rev up freely without boost ?

since the AFC should keep it from overfueling ?

I think it would have to be pass 20 degrees. Did you just change the timing?

i just completely rebuilt the motor, had the pump rebuilt aswell and told them that i wanted timing set at 20°

i used the pin and advanced timing by 7° so my guess is that they set the pump @ 20° and i must have advanced it to 27° ??

does that sound about correct ???

So they had the pump locked at 20 degrees? And you timed it a additional 7 degrees? Are you sure you only went 7 degrees?

Yes, unless it slipped ?

The 0 mark on the crank means TDC ?? correct ??

If not, how do i set the motor to TDC ?

looks like it slipped when i was tightening it or something...

am i correct to assume that i will set timing by sticking the pin in... this is 13,5°?

then the crankshaft pulley measures 740mm, divided by 360°... 2mm travel on the crankshaft pulley must be 1° so to advance timing by 7" i will turn the engine counter-clockwise by 14mm ?

Or do i turn the engine clockwise ???

Thanks in advance you guys...

I measured set timing the same way i had intended on advancing timing...

Timing had slipped and was somehow set @ 34° pre-TDC

So here's a write-up on how to set timing:

#1 - Turn over the motor with a crank bar with the timing hole on the pump open until you see the timing marker, insert the timing lock pin.

#2 - Loosen the nut on the pump, it would be a good idea to have someone hold the crankshaft still so that you won't break the lock pin, then give it a bump with a hammer on each side until the gear pops off the axle.

If you already have your TDC in order, you will not have to do step #3..

#3 - pull out your #1 injector and stick a long screwdriver in there so that you can see it move up and down, mark on your crankshaft pulley (i used the crankshaft sensor to mark by) when the screwdriver stars to move down, both when you turn it clockwise and counterclockwise, on my engine the TDC duration measured 38,5mm this is equvaliant to 19.25° variant in time, so you have to mark the center of this zone on your pulley... that is 19,25mm (on my engine, again this may differ on yours) from each mark you've already put there...

#4 now you have TDC... and with your lock pin in place on your pump you will have 13,5° timing... you can now advance or retard timing by turning your motor counter-clockwise (to advance) or clockwise (to retard) by 2mm (giving that your crankshaft pulley is 740mm round like mine) for each 1° you want to adjust..

This way is both easy and not as time consuming as using a clock and needle...

It took me less than 40 minutes to set timing on my truck and now it no longer smokes white or pops...

I lost one freeze-plug though, i'm unsure why though because they're new... my guess is that they were not the correct size since they were GM freeze-plugs...

I will definately order new plugs after the weekend and this time i'm going genuine Cummins parts.. ;)
