Several years ago i had a R4 GTL, unhappy with the performanse of the carburettor i contacted a company called 'The Carburettor Hospital' in Rochford, Essex.
They informed me that there was a Zenith Carburettor that could fit in place of the Zenith 28IF.
They supplied and fitted a Carb (the no. of which i cannot remember), a zenith with Mechanical Fuel accelerator pump.
They also had to fit a new airfilter, a sports one on the top and modify some of the linkages, but they did not replace the manifolds.
If i remember rightly they elongated the carb holes very slightly.
When i collected the car i was dumbstruck to feel the extra power, in fact the power i would say was a little too much, (dont laugh, oh alright then, just a bit!).
The car reacted almost like a 1400cc, it was fast to accelerate, could hold 85 mph all day and unbelieveably the consumption was slightly better.
I had a lot of fun with it, letting the likes of fiestas and Corsas roll up behind me expecting me to move over, only to leave them behind.
Sadly the car was later written of by a drunk driver whilst parked, and alas i did not keep the carb, but i'm sure it should be still available if anyone wants one.
