Tech Tip Helpful

Dear Sirs,

Many thanks for your fine publications, both Moss Motoring and the MGB parts catalog. Both have provided invaluable assistance in maintaining my 1966 MGB-GT. I have a comment regarding a Tech Tip in the MGB-02 parts catalog.

Following a break-in and theft of my MGB’s stereo, I decided it was time to convert the electrical system from positive to negative ground. I followed the procedure on page 55 of the parts catalog as well as the procedure for conversion of an impulse tachometer on page 98. Both were very clear and easy to follow. However, it took several weeks of driving in the dead of summer in Southern California before it dawned on me that the circulation fan was turning in the opposite direction. A quick switch of the wires at the fan solved the problem.

Again, thanks for all your help.

Editor Note: For those of you that are confused, Stewart is talking about a heater fan not an after market electric engine cooling fan. Hard as we try, we sometimes overlook very important details, and it’s comments like these, from you our readers, that help so much. Thanks again!

Gentlemen:

Your new MGA parts catalog is tremendous! What a valuable source of information. Thank you very much for sending me a copy.

There Is No Equal

To the editor.

Recently receiving catalogs MGB-02 and MGA-11, I would like to commend you and your staff for such a meaningful and informative piece of art. Without a doubt, there is no equal! Your technical tips will help every enthusiast and his/her marque.

Your quarterly newspaper is well-written and informa­tive but it’s the sale items that find me picking it up again to make sure I didn’t miss a bargain. This added extra makes me feel like I belong to a ‘club’!

Thank you to a well- organized firm with some obviously talented personnel.

Tech Tip

Loose Cap?

Car won’t start, and lifting the bonnet reveals the dis­tributor cap has come off? Replace it, and everything’s OK? How did it come loose?

Check for a perforated vacuum advance diaphragm. Inlet manifold vacuum can send fuel vapor from the carbs down through the line, through hole in diaphragm, and into the distributor. A little vapor build-up and a spark from the rotor when it meets the cap lugs can set off a small explo­sion that dislodges your cap. Vacuum capsules are often faulty and should be checked if ragged acceleration and general lack of power is a problem.

(Ed. note: overheating at highway speeds is often the result of a defective vacuum advance unit.)
