PeachParts Mercedes-Benz Forum - View Single Post - It runs! But barely- IP, valve timing, both?

Well I actually got it to run today, the 300SDL that is.

I was priming my new/used IP and only getting fuel out of DV's 3, 4, 5 and 6.

I gave up and connected the lines up, cranked it over and it actually started.

However, I had to put the pedal to the floor to keep it running and if I let off it would sputter and die. Got up to about 1200rpm at one point. It also smoked as if that were it's sole purpose.

So I'll need to check DV's 1 & 2 to see if they're putting out fuel but I'm also wondering about IP timing and valve timing.

I recall reading that if I was even 1 tooth off on the camshaft that the valves would hit the pistons. Since my pistons are not hitting my valves I presume that the timing is good. I also checked the camshaft mark to the crankshaft and it looks good but I think the pointer bracket that lines up TDC on the harmonic balancer may not be perfectly placed (why is that damn thing adjustable!?).

So assuming my valve timing is good and I DO have fuel out of DV's 1 and 2, would the IP timing being off create this type of running condition?

If it's none of the above and I've missed something feel free to point that out as well.

Thanks!
