Fix It With Steve...

Hi Folks,

I want to share one successful story with you thanks to Mark Zapf. His 1979 MGB fuel gauge wasn’t working. I did the usual test of taking the wire off the sender on the gas tank & grounding it. The gauge then read full, meaning everything is working apart from the sender. I then repeated the test, this time checking the sender was grounded using another wire and the gauge still read nothing, confirming the sender was faulty. I remembered reading an article somewhere recently that one of the properties of unleaded gas is that it can result in a coating on the coil of the sender rendering it inoperable and it could be cleaned. Well Mark went off to investigate and has reported back that one bottle of “Techron Complete fuel system cleaner” and a few hours later and his fuel gauge is working properly. So if this is happening to you try this solution. It might be a whole lot quicker & simpler than changing the sender!

The ‘Fix-It’ Garage was closed on Sunday 9/13 for the BCU. Of course it was great to see many of you on a perfect day, though it was less so for me as I now have a sick 1967 Mini to diagnose & fix…………


The Fix-it Garage was closed also on the 9/26-27 weekend so I could take part in the Wine Cheese & Beer tour. It was a wonderful weekend once we got over the weather on Friday night. There will be a full report in Driveline but as a ‘taster’ we had a total of 20 cars including 2 moderns on the tour. I found it interesting to note that I have worked on 10 of the 20!

For those of you with later model B’s using the single Stromberg carburetor its worth remembering that there is a rubber diaphragm in it, and like all things rubber it doesn’t last forever. Eventually it will fail and then the inlet manifold vacuum won’t pull the piston with the needle up and out of the jet so the car will have a somewhat ‘strangled’ performance at best! Checking & replacing it periodically is a good idea and carrying a spare is always a better one. However a temporary ’fix-it’ can be made with electrical tape as we proved on the WCB tour.

During the week I changed the front springs on my GT with the help of Kim Tony. It no longer has that nose dive look and the steering is not surprisingly lighter. Another job completed.

CMGC Project Car
Club Car Work In Progress!

Our Tech Coordinator, Steve Skegg, has graciously volunteered to host, and manage therestoration of the Club's newly acquired MG-B-GT! We will be looking for members who are interested in helping out. No special knowledge is required, because we want this to be a learning opportunity for all club members, at all skill levels. What better way to learn the in's and out's of an MG than under the watchful tutelage of the club's own master mechanic?
It doesn't hurt that Steve's garage is also heated and air-conditioned!

List of work sessions status: (order determined by availability of parts & manpower)
  Install the new electronic SU fuel pump, correctly
  Brake/ Clutch hydraulics. - rebuild the brake pressure failure assembly with a new shuttle valve & seals
  Engine / drive train refurbish - fluids change, prop shaft reversal & connection, radiator support & tray install & getting it started.
  Windscreen replacement—waiting on proper gaskets
  Interior install – interior upholstery, seat belts, door locks — most work complete, a few touchups are required.
  Body, clean, paint touch up etc.

Workers can expect to turn wrenches, and get as hands-on as they like, in a relaxed atmosphere. Steve has all the tools needed, so the only thing you'd need to bring is your enthusiasm! Since we'll be working on an old car, wear cloths that you don't mind getting dirty.
