Re: 250 Gte Distributor

Chris, the centrifugal force starts moving the weights at about 500 RPM and at about 2500 RPM they have been flung out as far as they can go. So, in a standard distributor your advance starts at 1000 engine RPM and it maxes out at about 5000 engine RPM. Here is my reference for setting up the advanc...

Re: Carb sync tool for Weber 36 DCS

I use the snail type with good results on my 36 carbs. For an adaptor, take a one-inch Sched 40 PVC coupler and turn one end of it at a 5-degree taper. Glue a two-inch section of pipe in the uncut end of the coupler. Insert the pipe inside the rubber snorkel of the meter and wrap a wire tie around i...

Re: gas gauge sending unit 330 GT 2+2

George, you might be able to get a cheaper replacement, but you have to retrofit the float arm. The other thing is make sure that the replacement has a warning light terminal.

Re: gas gauge sending unit 330 GT 2+2

Put the unit in a steady hold (like a vice), connect your meter, then sweep the arm very slowly from one end to another--the way it would move inside the tank. From empty to full it should range about 20 to 100 ohms.

Re: gas gauge sending unit 330 GT 2+2

George, I don't know what to say. if there is no continuity between the coil terminal and the chassis of the sender then that means the coil is open. You may want to check for these: Is the coil unraveled? Is the coil discolored like it's overheated due to a short? Is there moisture oxidation in the...

Re: Belt dimensions for 250 Gte engine S3?

If that NAPA item works and you prefer a more "appropriate" Pirelli, here's the correct one. The NAPA one is toothed, while the Pirelli one is pricier.

Re: Belt dimensions for 250 Gte engine S3?

Chris, I was using a NAPA belt with this number: 25-09783/7385. If you need the length I can measure it.

Re: Belt dimensions for 250 Gte engine S3?

I got a replica "correct Pirelli" belt from Parker Hall. It's for the earlier 3.0L motor with generator. It measures 95cm long on the outer surface. I couldn't use it because my car has an alternator.

GTE water temp switch

Hi Tom, in your recent blog you were talking about a water temp switch being adjustable. I presume you are talking about the fan switch. Are you? If so can you explain. I am very interested in learning about it. Thanks.

Re: gas gauge sending unit 330 GT 2+2

George, there are two terminals on the sending unit. One goes to the gauge dial (brown wire, labeled "T"), the other goes to the gauge warning light (green wire, labeled "W"). Connect your ohmmeter from the "dial" terminal to the chassis of the sending unit. Swinging the float arm from one end to an...

Re: gas gauge sending unit 330 GT 2+2

You might try removing the wires from the sending unit and measuring the resistance from the coil terminal to the chassis of the unit. Do you know how full your tank is? The E-F range of the coil is 20 to 100 ohms. If your coil is working you should get a number in between. Shake the car and see if ...

Re: rebuilding ignition switch

These switches are generally simple and repairable. I had an issue with mine; one day I couldn't shut off the engine. I took it apart and found those brass hex nuts to be loose, shorting the two paddles. That's all it was. I remember it was a much bigger deal removing the switch from the dash and re...

Re: Oil flow path

Tom, here is one from the Merritt book for the inside plug motor. The difference is that your full flow filter is an external cartridge. Here the filter is a strainer inside the timing case. Hope this helps.
