Thanks Jim, That seams to have worked although I did get a double backfire through both carburators. Could that be from beeing too advanced? Thanks again George -- Original message -- In a message dated 7/30/2005 10:28:39 A.M. US Mountain Standard Time, [EMAIL

[MBZ] Dwell - saga complete Now can't set timing

I reveresed the coil wiring and took the dwell meter from under the battery, like Dan(benzbarn) suggested and I was able to get set the dwell properly. 41*. Thanks Dan! Woohoo! Now I'm trying to set the timing and I'm turning the distributor and every thing is fine at about 1000 RPM 10 BTDC.

Re: [MBZ] Dwell - saga complete Now can't set timing

BTW, The fast idle screw is missing from my carburators. Would this be related to this problem? Is the fast idle screw, just a screw w/ a spring? is that something I can get at home depot? if so doe anybody know the screw size length? Thanks George -- Original message

Ok. Went to Autozone (I know I know) and picked up another set of points. Dan, The housing is metal, magnet stuck, and the last digits of the casting is 187 003. I did not find an oil cup on the side of the housing. There was a ball and the plates that moved all got point grease. moves much

Re: [MBZ] Dwell - the saga continues

Hook your dwell meter right at the end of the green distributor wire where it goes to a small junction box. There should be a small metal post sticking up - hook on there. You can't take a reading off the coil like a regular system. Dan

Hey Dan, Benz did quite a few changes to this model as the ran out of parts. I beleive they also went from a 2.5 to a 2.8 somehere in that time as well. I did pull a vacuum and the cell. Both the advance retard do work. In fact it's kinda hard to start the vehicle without the advace. Don't

[MBZ] Dwell

Hi all, I have a 72 250 w114 M130 and I was trying to adjust the dwell. the closest I got it was 51*. I tried everything from 0.06- 0.19 feeler gauges. I'm guessing that the points are bad. Can someone second that guess? Thanks George

Re: [MBZ] Dwell

If the dwell doesn't vary with gap, the points aren't making contact properly. Dwell is actually closed time in degrees of rotation -- do make sure you have the meter set for (or are reading) the six cylinder scale -- else they read wrong. New ones are about $8, foolish not to replace them.

Re: [MBZ] Dwell

Re: [MBZ] Dwell

Standard direct points will last maybe 5000 miles. Points on transistor switch coils will last maybe 15,000, not usually more. Dirt or oil kill them, make sure the new ones are lubricated correctly (a tiny amount of high melting point grease on the BACK side of the rubbing block, not the

If you have the aluminium distributor it should be set to 30 degrees.

Thanks Jim, I'll check it out. There is only 120K on the vehicle but it could be premature wear. If it is failing, is there a rebuild kit for it? Thanks George -- Original message -- In a message dated 7/27/2005 7:07:51 P.M. US Mountain Standard Time, [EMAIL

Re: [MBZ] Dwell

I rebuild distributors here with a proper distributor testing machine. CD ignition stands for capacitive discharge, an early electronic ignition device. Put a magnet on the housing which should fall off. Pretty easy to see if it's aluminum or not. Dan

Re: [MBZ] Dwell

If you oil the felts on the main shaft through the oiler they last a long time. The original bushings are usually steel but the replacements are some sort of brass - possibly self lubricating.

Re: [MBZ] Dwell

One of the problems on cars with CD ignition is that people never service the distributor. Since the points will last much longer, the normal light oiling during change out usually never gets done. The rubbing block needs a bit of point grease, oil cup on the side of the housing needs a few
