Hey Mak, The emissions portion of my vehicle is not functioning. MB does not sell replacements.
Any idea how the EU version was setup timing wise? the US where at 4 ATDC. That had a vacuum to retard the timing and would kick it up as you accellerated and switched over to advance. This is a M130 250. BTW I tracked down my problem to the two carb mounting gaskets. Found it with some carb cleaner. Tightend it up and ran much stronger. Put it in gear, didn't stall, released the brake and had no problem with the uphill driveway.
