  1. In the Stanpart catalogue the spacer is only listed for the solid axle suspension (plate W). It’s not listed at all for the IRS (plate V). Jim
  2. Andy, +1. When I bought my TR4A, it had a Pertronix distributor installed by the PO. It ran fine for several years, but this Spring, the mechanical advance failed (tore itself to pieces actually). So I purchased a refurbished stock dizzy/points from British Vacuum Unit. After dialing in a little extra advance, the car has never run better! Jim
  3. Keith, hmmm that might be something for me to do over the winter. I tend to take a “belt and braces” attitude with these cars anyway. Jim
  4. Keith, I have the rectangular ones. With the shims, it did raise the water pump outlet approx 1/2 inch higher than radiator inlet. There was enough flex in the upper hose (I installed a new one) to fit ok. I was concerned a little about trapping air, but after a year, there have been no cooling issues (touch wood). Jim
  5. Even with a narrow belt it’s a squeeze, at least on my car. So I also replaced the motor mounts, and shimmed them with 2 heavy washers per side. Now there’s just enough clearance to get the belt through without a struggle. You know they only break at night and in the rain! Jim
  6. I believe there’s an article about it in this months TR Action. Jim
  7. I just fixed a similar issue on my car. Left turns cancelled but right turns didn’t. I checked and the directional signal canceling cam was offset when the wheel was straight. So I guess it never had enough travel to cancel on right turns while driving. Here’s what I did to fix it: - set the front wheels straight ahead. - remove the directional signal escutcheon so the directional signal cam and directional signal trigger lobes are visible. - loosen the upper steering column clamp (#5-10) so the upper outer column can rotate freely over the upper inner column. - rotate the steering
  8. Folks, I just wanted to update this and say that after receiving and installing the refurbished 25D dizzy from British Vacuum Unit, the car runs GREAT! So the dying Pertronix dizzy, (broken mechanical advance), was the culprit all along. Thanks to all for the help here and in my “Hesitation” thread. BTW - not sure if you are familiar with a Triumph restoration shop here in the States called Macy’s Garage, but they have a good write up on setting up a dizzy, which I used: https://macysgarage.com/ign-timing.htm BACK ON THE ROAD!........... cheers Jim
  9. Not to diverge from the topic, but are front stub axles susceptible to this type of failure? I know suppliers offer front stub axle “upgrade” kits, or are they to solve a different problem? thank Jim
  10. Don’t the butterflies have a bevel, that if reverse mounted, can cause an “open throttle” condition? Jim
  11. Hello Peter, unfortunately all I have is the failed Pertronix dizzy, so no original one. BTW - I contacted the Distributor Doctor and they offered a rebuilt Lucas unit, but with shipping it was very expensive. However folks on the Triumph Experience forum recommended the outfit, British Vacuum Unit, located in New Hampshire. They also offered a rebuilt Lucas dizzy, but at a more palatable price. They also warned that many of the new reproduction units have advance curves that are incorrect. Anyway, I agreed and it’s in the mail! Jim
  12. Thanks Ian. I didn’t realize he sold them outright. Jim
  13. Folks, I just discovered that the Pertronix distributor in my TR4A has failed (see my “Hesitation” topic). So now I’m looking for a replacement. I think I want to go to a stock distributor with points. Does anyone have a recommendation for a supplier, as I’ve read that some of the new distributors being offered are less than ideal. thanks Jim
