76' 240D Loss of acceleration

My car has lost it's acceleration and this is a necessary item on a 240D. It's most noticeable when I am merging onto the freeway. The car will only accelerate slowly only after I hold the throttle pedal completely down and count to 10. It's as if no fuel enrichment is occurring. Yes, fuel pressure is fine - I run an electric lift pump. And yes, the linkage operates in the full range. Is there a load sensing rubber/metal diaphram on the back of the p-pump that could be cracked? I noticed a vacuum line going to it from near the throttle plate.

Starter Pull Switch

Hey all,

I've went to start my 115 1975 240D yesterday, and the pull switch would not pull out. Like its locked in place.

I've got it out of the dash and trying to find out if there's some kind of bi-directional action on the key, but it doesn't seem to be doing anything when I turn the key.

Anyone had this problem. It doesn't feel like it starts to move.. it feels like a mechanical lock.

Any idea what could keep it from pulling out from the off position?

81 300SD transmission seals are leaking ??

My transmission has developed a leak at the front seal. How difficult a job is it to perform as a DIYer? What other seals should be replaced at the same time? If out of the range of DIYer, what would be an estimation of how much professionals would charge? Is this something one could expect a local Aamco could perform correctly? Thank you in advance for your response.

transmission kickdown switch adjustment?

I have a 1983 300d. The accelerator pedal is not engaging my transmission kickdown switch on the floorboard. It makes contact with the switch but does not mash it down enough to engage the switch. Does anyone know the best way to adjust the throttle linkage to take out the free travel in my pedal and adjust it so that it completely engages the kickdown switch? Thanks for the help!

Changing to Crane Electronic Ignitition

I have a 1972 280se 108.067 4.5 Mercedes. I had a problem with the
Ignition COntrol Unit and placed a wire in the car's plugin recepticle
(to ICU) connecting 2 of the plugins tabs. Thus bypassing the ICU
completely. I have tried a new ICU and it didn't solve my problem. It
runs??
My question is, by installing a Crane Electronic Ignition, will this
eleviate the ICU problem and improve the car's performance?
Thank you for reading this inquiry.

79 240D oil pressure?

My 79 240D just got a new (used but better than it had) engine.
The engine starts good when cold (20 degrees now) and has good power for it's age.
I'm running Schaeffers 9000 series 10/30 synthetic. Had good luck with this oil in other diesels we own including old dodge cummins, and our new 09 volks 2.0 tdi.
And maybe what it's doing is no big deal, but it doesn't seem right.

300D Vacuum Pictures & 5 way connector

Does anyone have any detailed pictures of the vacuum lines and connectors under the hood of a 1981-1985 300d? I a starting from scratch and the diagrams that I have found don't specify whay types of lines to use and they are vague at best on how to run the lines. Please help! Also I have seen a 5-way connector in some cars and the vacuum connector kit on this site does not include this? When was it used and on what models? I have the vacuum troubleshooting guide but it lacks the detail that I am looking for it this situation. Thanks for any and all the help!

WVO is exempt in WA

Well I was ready to go back to the Legislature again this year to try to get WVO as a fuel exempted from road use taxes, but I do not have to. Representative Dan Roach's administrative assistant contacted the Department of Licensing or Revenue and was emailed the following response.

Administratively we accept Waste Vegetable Oil as “biodiesel” even though the exemption states: “(k) Waste vegetable oil as defined under RCW 82.08.0205 if the oil is used to manufacture biodiesel.” The manufacturing v. processing to use WVO was not significant and the intent of the law was to exempt the WVO. We do exempt the WVO from tax as long it is for personal use only. The WVO sold as a fuel is subject to tax.

We are exempt for road use tax, that is a wonderful thing.
