How about the carb needle? I believe I have the "M" needle in my 948. Is that correct for the engine? Which needles are a step leaner and richer if I want to tinker?

Re: Fuel pumps
Speaking of "that supplier," I've tried to order from them twice. A completer pump, and then an overhaul kit. In both instances, they were out of one part or another, and lead time would be measured in months. I cancelled orders, and went elsewhere. Is my experience typical?

Re: Fuel pumps
My car came with the wrong SU pump installed, a HP pump. I installed one of these electrics and it leaked badly immediately. From there, I went to a mechanical pump (cheaper) which worked fine. I'm mow back around to the proper SU LP pump. Nothing wrong with the mechanical, but I prefer the electric.

Re: some things gone wrong!!!
Or try this from our side of the pond. $175 is about 120 GBP. No tax. No exchange. Even with shipping you'll come out better. You'll have to wait a bit longer. http://www.ebay.com/itm/1275-Cylinder-Head-Bead-Blasted-Crack-Tested-Chambers-Swept-No-Lead-Ex-Seats-/161148391305?pt=Motors_Car_Truck_Parts...

Re: some things gone wrong!!!
Do a good "autopsy" as you dismantle the head. Look carefully at the contact marks on all 8 valves and seats where they make contact. Put a straightedge across the head. Shine a light behind it and look for light leaking under the edge. Do the same for the block.

Re: some things gone wrong!!!
"It would bolt on but the valves would hit the block.
You would have to get the block machined/pocketed."
Is that true? Is that where the 0.320 measurement comes from? Does the 940 head start with the standard 2.750 thickness?

Re: some things gone wrong!!!
Exactly my symptoms, it was the head gasket. Don't just replace it without checking head flatness. I could see a lot of light beneath a straightedge. Follow the rules about tourquing the head, adjust the valves, run it a good heat cycle, torque and adjust again.

Re: Coasting to a stop
"clatter the pump with something hard"
In Sophisticated engineering terms, that's referred to as "Inertial Modulation." Also works well with vacuum tube electronics.

Re: Make a key for this locking fuel cap
My cap is different. This cap grabs the inside of the fill tube. My cap grabs the outside of the tube. When did they change?
Can I get an "inside" fill tube? The "outside grabbing" caps are less common, and the gasket won't stay in place.

Re: Coasting to a stop
If the carb bowl is wet with fuel on the outside and dripping, then it's the float in the bowl is not keeping its level, and flooding out the engine.
Crud in the line contaminating the float valve or leaking float.

Re: braking pedal query
When you say the pedal goes down and "stops solid," can I assume all four wheels have the brakes applied and are immovable? Is there any drag at any of the wheels when the brakes are not applied? Have you looked at the shoes, return springs and wheel cylinders? Is everything free in there?...

Re: Running in oil
First, I'm not disagreeing with any of the above postings. I'm just going to tell what I think is the history and logic behind "running in" oil. My experience comes from Airplanes I've owned. They were from the 1940's and low horsepower, (85 to 145 hp.) Back in the day, engines didn't have...

My wood "proof of concept" model was pretty good, but hard to get repeatable results. I made up a more substantial tool from steel and aluminum. All is well: front-back, left-right, all repeatable. I'm better at steel and aluminum than I am with electronics. I can't get pictures to post. H...

Is it the original gearbox, or has it been rejuvenated at some point in the past. I opened up a core gearbox and found the hub detent balls and spring shards in the bottom of the box. Be sure you have the maintenance manual, and follow every step. I printed the pertinent pages and had them laminated...

Re: Toe In Measure Tool
Good question, I'll try that tomorrow. I'm convinced by the improvement in the steering that the engineering is good enough.
There is an old saying:

Toe In Measure Tool
For what it's worth, I've built a quickie toe in tool. Very low tech, but it worked for me. I adjusted two cars, and noticible improvement on each. One was about 15mm toe in, the other about 10mm out. They are now at about 2-3mm toe in. Step 1, build the jig. Just touching the rim fore and aft. On m...
