Re: Fuel gauge reading half-full when empty

Thank you. My car is a Series 2, which has now got a later Speedo with bimetallic gauge & voltage regulator. The fuel tank is a 6 1/2 gallon but the sender is the early type used with the gold gauge. The car is converted to negative earth. It the tank wasn't brim full, I'd take the sender out. S...

Re: Fuel gauge reading half-full when empty

Does anyone know the correct resistance through each type of sender unit at high & low fuel levels ? My Series two has non original speedometer & fuel tank. It did seem to work until recently when I ran out of fuel with the gauge still indicating half full. A good job that I keep a can in th...

Re: Heater casing refurbishment

That rings completely true . My car has a Mini heater, with the fan motor marked + & -. If the fan spins Anticlockwise (viewed on fan end) the air velocity (measured by anemometer fixed in the centre of the intake) is about 10 to 15% more than when turning clockwise. I have now assembled & f...

Re: Heater casing refurbishment

I noticed a comment on here that heater fan rotation is the same even when earth polarity is changed and that the same fresh air heater was used on Minis. I beg to differ. My S ll has had a fresh air heater from a Mini installed since 1986. I've recently converted to negative earth & the fan goe...

Re: 1098 clutch in 948 gearbox

I had (wrongly) understood that you could only get a starter ring on a flywheel (information source was an BMC workshop manual). I learnt late last night that the rings are available, even cheap. Fitting one, looks very much like when I saw my grandad making cart wheels, around the time my car was m...

1098 clutch in 948 gearbox

My Series 2 has had a 1098 engine with a 5/16" backplate and 948 flywheel, clutch & gearbox since 1976. It has worked well but now the starter ring is worn (even after a 90 degree turn on the crank many years ago) & the gearbox output drips oil. I still have a good 1098 flywheel & c...

Since it will probably be warmer weather before I drive anywhere, I might just see how it goes then.

Stale petrol

The RAC & others would have us believe that petrol deteriorates appreciably after few months. My car has 10 year old petrol in the tank. It starts but only after turning the engine over for a long while. It is said that the old petrol becomes more dense, less volatile, less calorific and might p...
