I recently bought a reconditioned Carburetter from Ebay for my 1971 R4 845cc, it was a zenith 281f ( V. 05 078A ) but from a 1984 R4 GTL .
The Carburetter I took off my car was a Zenith 281f ( V05 069 ) a different number from the one that I bought, I was getting black sooty smoke indicating an over rich mixture, although I have set the mixture screw to the correct setting and the smoke has abated quite a bit and the plugs aren't as sooty black as before..
The car is reaching up to 60 MPH but in a rather sluggish fashion, is this because the Carburetter I've put on has a different set up, or could it be the points / coil need replacing or both.
I do understand that the 1984 GTL would have come off an (1108 cc) engine, is this my problem?
