In September 1962 the British Motor Corporation (BMC) launched their replacement for the very popular MGA sports car. The MGB was larger and more comfortable and getting up to a top speed of 103 mph, overall fuel consumption of 28 mpg and an affordable price of £949 including £259 purchase tax.
Nobody imagined that the MGB would last for 18 years and produce over half a million cars and become the fastest selling MG of all time. Today it is one of the most popular classic cars, being relatively cheap to buy and affordable to run. In place of the MGA’s separate chassis was MG’s first bodyshell which made the car stiffer than other contemporary sports cars, although it made it rather heavy too.
The MGB has a classic looking shape and good handling. However modifications are available to improve on the design to increase its safety, performance and road handling. Its rear wheeled drive lets you really feel cornering.

An Antique MFY 32R MGB ?I visited an Antique Preview in August 2002 with my wife Fran. There were some very nice curtains - the "Swag and Tail" variety which I and Fran were keen on and also a superbly restored MGB Roadster, a Morris Minor and a Ford Chummy.I went on my own on the day of the auction to bid for the curtains. There were a lot of ladies bidding for the curtains and I lost out. However only three people were bidding for the cars! I put myself a limit on the MGB not thinking I stood a chance. I was shaking with excitement as I bid and the bidding stopped at me! I phoned my wife to give her the good news and I said, "I didn't get the curtains, but I got the MGB !" Her retort was "where the Bl---- H--- are we going to put it on the Window!" |

This is our 1972 MGB Roadster. We have had the car since 2002. The car is actually Blaze, and is mainly an original car. |

When I purchased our B in 2002 from a local garage it hadn’t been used regularly for a number of years. Hence the problem of unsmooth running became apparent on my very first test drive. The car was very “lumpy” and refused to start without full choke even on the warmest of days. This I endured for a while. However, wanting the car to run at least like it was when new, 30 years ago I began trying to find out what the problem was and to rectify it. The carbs were rebalanced and set up properly, new needles where fitted, as the old ones were the wrong ones for the K&N air filters that had been fitted in a previous life. A full tune up improved the cars performance tremendously. But the car still didn’t run like I knew it should. Whilst out on a good run the car would perform ok, but on the return journey would often cut out when under load, like climbing a hill on the motorway. Out on a long run to Wales the car started coughing and spluttering on the road home and eventually broke down and had to be recovered by the AA. ![]() The repair man agreed with my diagnosis that
the probable cause was an intermittent fault on the fuel pump. I
replaced this and the problem was cured again! The next good run out did
exactly the same on the way back home, stating to misfire under load,
but this time just managing to limp home. Having replaced the fuel
pump, in line filter and checking all the connections I was convinced
the problem was electrical. I began

A little bit of History on the car.I acquired the car in March 2001 and used it on the London to Brighton run in May of that year, unfortunately the head gaskets failed before we got there 50 miles short. Diane and I managed to drive the car back home with Brian and Margaret’s help. The cylinder heads were removed and sent to a local machine shop to be skimmed and checked. Unfortunately they were found to be scrap due to porosity. Two new Rover V8 4.6 cylinder heads were located on E-bay that had been polished and ported which had been removed of a development Range Rover test vehicle. During the rebuild a Piper Sport cam was fitted with and a Holley 500 CMF Carburettor and Mallory distributor with two sets of points. The front brakes were upgraded with thicker discs and four pot callipers as fitted on the old Ambassador Wedge shaped vehicles. The back-axle was also changed from the standard 3.7 Ratio as on the 1.8 MGB to the MGC 3.3 Ratio wire wheel axle. 15 inch wire wheels with low 195x60 profile tyres with 72 spoked wheels were fitted. Engine improvements performance has gone from 135 BHP to around 190 BHP.

New floors, sills, doors, wings, boot floor, rear wings, valences, plus a few more bits and bobs. Not much if you say it quick.After removing every nut and bolt a hot air gun was used to remove the underseal so that the shell could be grit blasted and then etch primed. All rot was removed and replaced by new steel, then floors, sills, new boot floor and chassis legs, complete rear wings with valance and rear quarters were welded inThe whole underside was seam-sealed to prevent moisture ingress, then primed and coated with stonechip before final painting. After careful preparation the shell was then primed and finished in an original MGB colour, RD9 Tartan Red. The boot, bonnet and doors were painted separately to achieve a more even finish. The top joint between wing and scuttle was not filled so that waxoil could be introduced into the joint to prevent the usual rust trap. All box sections were pressure treated with Waxoil including enclosed wing areas.Whilst the body was receiving lavish care and attention, some of the smaller components were shot blasted and powder-coated. The front and rear suspensions were completely stripped, blasted, powder-coated and rebuilt using new components. Rebuilt front and rear suspensions were bolted to the body to give a rolling chassis, which was then systematically rebuilt using new and reconditioned parts.The engine which had been tuned to stage 4 with 10:1 compression ratio, was de-tuned to 8.8:1 with bronze guides and hardened seats, to run on unleaded fuel. The strengthened rockers and steel crank were retained together with a Piper BP255 mild road cam. The Crank, Conrods, Pistons and Clutch were fully balanced.New bearings were fitted to both front and rear axles, copper brake, clutch and fuel lines were fitted along with a new cotton covered wiring loom.




investigating
everything electrical. I replaced the distributor cap, the leads, the
rotor arm and cleaned all the low voltage wiring. The points were always
a source of trouble, needing constant adjustment and replacing, so I
invested in a magnetronic electronic ignition system. This made
such a difference. The car started up with virtually no choke and
run smoothly even before it was warmed up. I was so pleased that
at last I had cured the problem. I went for a test drive and filled up
with petrol, this is a clue to what the real problem turns out to be in
the end. I was amazed at the difference it made to the cars
performance. It was certainly the best the car had run since I had
it. However my satisfaction was short lived when the next time it
went out for a long run it started doing the same on the way beck home!! Ah! I was getting very annoyed with finding the problem. I again
turned to the fuel system. One thing I hadn't tried was just to
see how efficient the new pump was in delivering fuel to the
carburettors. I put a pint glass at the end of the pipe and switched on
the ignition. To my amazement there was a large quality of air bubbles
coming out of the pipe. There had to be a leak some where or in
the fuel tank itself. I filled the tank with as much fuel as you
could get in and tried the experiment again. The same happened.
I was now really scratching my head as to where air could be getting in.
I put the glass on the outgoing pipe from the pump and air was still
coming out. I looked at the "solid" pipe from the tank to the
pump. I removed this pipe and under the wheel arch there was a
clip holding the pipe in place. At the back of the clip there was
a hair line crack in the pipe! Eureka, I replaced the pipe and put the
glass by the carburettor and switched on the ignition. Within a
couple of seconds the glass was full with fuel. Steve Moore
