Classic British cars have survivied—and thrive still today—only by the generosity of individuals sharing what they’ve learned. It’s the heart of the hobby. The Sales and Tech Support teams at Moss do our best to continue this rich tradition, too.
Below the first Top 10 are many more worthwhile honorable-mention tech tips. No doubt there are thousands more to add. Tell us yours in the comment area at the bottom—see if you can keep with the theme and write yours in 20 words or less.
TOP 10, 20-WORD TECH TIPS
1. If you know HOW it works you can fix it, ‘cuz you’ll know what’s broke. Al Amato
2. If you are having a problem, never assume a system has not been modified by a previous owner or mechanic. Wade Karhan
3. Problem with car: frustration, ale, research forums, purchase parts from Moss, fix car, drive car, smile, enjoy life… Eric Alley
4. Take a moment to think about the most recent things done with the car, no matter how simple. Then evaluate. Kim Wroblewski
5. Many electrical problems can be attributed to bad grounds. Clean your grounding points and protect with a corrosion inhibitor. Jack Collins
6. When removing frozen fasteners DO NOT use force. Soak it in penetrant and work back and forth with increasing torque. Tom Moors
7. Hard starting? Runs rough? No power? 80% of suspected fuel problems are electrical! Check spark then fuel delivery. Chip Krout
8. Replace the points-type ignition in your distributor with Pertronix or Crane electronic ignition. Low cost, more reliable, low maintenance. Alan Hunter
9. Installation is the reverse of removal. Sometimes. Ben Grabow
10. When installing rubber parts that tend to move around use a drop of super glue to locate them. Richard Carr

HONORABLE MENTIONS:
Before doing any electrical work—disconnect the battery. Larry Newman
Zinc was removed from modern oil. Flat tappet cars need zinc additive to prevent cam failure. Learned the hard way. Stephen Benelisha
Always make sure your grounds and battery cable ends are clean and your SU dampers are filled with oil. John Perkins
Check oil gauge with tire pressure. Attach gauge line to tire using brass connectors, tubing and a tire inflator chuck. James Kopenhaver
Read manual; do simple things first; isolate if possible; seek help from fellow owners on MGE, and proceed slowly. Norm Nolde
Join a British car club and follow their tech advice. Trust me, don’t go it alone! Matt McKenzie
Read the manual first. Jim Johnson
Before you disassemble verify problem, re-verify problem, take pictures, take more pictures, take notes, take more notes, verify problem again. Jerry Woodward
Connect a relay kit and inline fuse to the headlight system and avoid electrical issues at night. William Luckenbill
When installing a new top, start by letting the vinyl relax in the sun on a warm day. Mike Eldred
Safety: Tie Rod ends with non-split pinned nuts are only for a single tightening—retention is reduced with repetition. Ray Splatt
When it starts great, but then doesn’t want to re-start, make sure you turned off the choke. Scott Hunsucker
MGTD: Jumping the two fuses activates the ignition same as the key. Consider other ways to secure the vehicle. Craig Leonardi
Use serrated washers on all threaded electrical connections, conductive grease (like Kopr-Shield) on push-in connections. Randall Carlson
Clean all threads, always start threaded items BY HAND, never use rusted or damaged bolts. Oil threads. Don’t over-torque. John Wolfe
The issues you face today are directly related to the decisions you made in the past. Stan Tucker
Start with simple things first. Something simple usually creates the biggest headache. When frustrated walk away and come back later. Peter Davies
Prior to charging a battery in a vehicle, always remove the ground cable. Melwyn Stephenson
Check thermostat and waterpump by watching the water in the radiator. The water movement shows open thermostat and pump action. Rudy Guerra
Electric fuel pump lost suction or stuck? Mityvac the steel fuel line under the bonnet to prime. George Blumb
Have your exhaust manifold or header ceramic coated to dramatically reduce heat in your engine and engine bay. Bob Canfield
Going to get your hands greasy? Put Vaseline on your hands first, makes it easer to clean up later. Bob King

TC has a leaky fuel sending unit? Lower the gas tank so the unit clears the spare wheel carrier. Peter Roberts
THINK about the problem, the steps to fix it, what the fix will be like. Sleep then reTHINK it. James Maddox
Always check front rotor runout when experiencing a soft brake pedal. Warped MGB rotors do not always cause pulsing brakes. Mark Smith
Oil pressure sender may not be dead; detach, fill with penetrating oil, tap a few times, reinstall, get lucky. Charles Fox
Get a test light and learn how to use it. Digital meters are often confusing and slow to react. Rick Patton
Remove heating system from TR6 and plug all hot water ports (3) including manifold to stop leaks. Mike Kramer
95% of the problems with SU carbs are in the distributor. First confirm correct timing, spark, and distributor wear. Jim Dougherty
If the engine doesn’t start, check your fuel, spark, and compression. It needs all three. Matthew Hux
Confusing electrical operation, dim lights? Check/clean ground connections starting with battery, then harness to body and finally bullet connectors. Jim Mattern
For easy starting, convert to electronic ignition, and always verify that you have the proper voltage powering your ignition coil. Eric Schulte
Proper LBC’s do not misbehave unless they have been subjected to Yankee misuse; regular checkups by trusted mechanic limit misbehavior. Irene Breland

Have an electric fuel pump? Wire in a cut-off switch under the dash. Handy in an emergency, and the simplest anti-theft device ever.

Never set a tool down in the engine compartment. A spanner jammed into the fan blades is no fun.

Great article except for the one about speakers and the cockpit/trunk panel. DO NOT CUT THE PANEL! There is at least one previous owner I’d like to turn the hacksaw to after removing a “custom” audio instillation from an MGB. If you want to have a 4 speaker system in a convertible, buy a Miata. If the radio isn’t loud enough, you’re too young to appreciate fine engineering.

the more you use the car the more reliable it will become, you will not neglect and you will fix the little problems that arise.

After replacing the brake light pressure switch for the third time on my 57 bn4 . I fitted a pressure switch to the brake peddle and and wired that in.Now a following motorist is aware I am going to brake rather than I have started to brake. Did it 2 yrs ago no problems, cost me 59 cents what do you think or is it an old idea Cheers DD

I did the same thing with my BN one luckily the guy was in the other half of the crosswalk when the whole top of the pressure unit blew off and I had no breaks.

I have a 1961 Austin Healey BT7, I have to remove the steering wheel. I removed the control head assembly, the big nut and can move the steering wheel 1 inch out then it stops as if there is a stop somewhere. Anybody can give me a hint to what is going on? Thank you, Andy
