Engine Numbers FOR UNLEADED FUEL
If the engine is still all original, use the engine numbers;
1275 Austin Metro engine fitted with unleaded heads : 12HE24, 35, 39, 40, 41,
42, 67 up to 75.
MG Metro 1300 unleaded post mid-1989 fitted with unleaded heads : 12HF01
MG Metro Turbo unleaded : 12HF01
Also, if someone had taken the car to a ROVER dealership for the 'ROVER approved'
unleaded conversion,
the ROVER bulletin that was issued with the corrected timing
figures, also stated that the fitter must stamp a 'U' on to the engine plate.
An example;
MG Metro 1300 leaded fuel pre 1989 12H996AA, would be 12H996AAU
Its fairly obvious because it would be stamped in and not raised like the other
letters.
(BELOW added 21 november 2002 from Dennis Watts)
Here is a list of 998cc engine numbers which are compatible with unleaded.
These refer to mini engines produced from 1989 onwards.
99H/D81P, 99H/E20, 99H/E21, 99H/E22, 99H/F16, 99H/F15, 99H/F32, 99H/G30, 99H/G31, 99H/G32, 99H/G33, 99H/G34, 99H/G39
all post 1990 1275 mini engines were unleaded compatible.
all previous engines require modification before they can use unleaded.
