I've done a lot of pump work on my car and I set the timing by "ear". It's not scientific but it's worked so far. I was getting a burst of clatter upon initial acceleration which indicated far retarded injection so I just advanced it little by little until the clatter went away.

I'd really love to get one of those acoustic interfaces to do a proper job of timing it though but their several hundred dollars.

Thanks. I have clatter too! I'm attaching the pages from my FSM. So it looks like I can loosen the securing bolts and just adjust the 30/1 screw?

I have a 1996 E300 with 220kmi on it. I highly doubt the chain has been replaced, I also have some white/blue smoke when cold and a little too much clatter. My injectors were tested /shimmed, they are perfect. Tank cleaned, good fuel, no bubbles in lines. Runs very good when warmed up with a little too much clatter remaining. Power is a little weak at bottom end RPM, good as it builds more RPM.

Possible to try adjusting the pump slightly to improve? Please explain steps in doing so, Pics. if possible.
Thanks
