Since changing the carburettor on my 2 litre Pinto from the jumbo Granada one to the correct Weber for the engine, I have never quite been satisfied that the engine runs as well as desired.
It now starts more reliably, ticks over reasonably, and doesn't cause any embarrassment in traffic.
I think the Grannie carb camouflaged various deficiencies elsewhere, such as ignition timing. Now that I have changed or adjusted all of the usual bits without spending a heap of money, the only obvious fault is that the engine is not always happy when accelerating hard or going uphill. It is either 'pinking' or making noises like slack in big-end bearings or piston-slap. Easing off on the go-pedal, and the noise goes away. Granted the engine is in theory 28 years old, but who knows what original internal bits it still has?
The camshaft is a Piper 270, so I have been advised that the dizzy is probably not suited and/or may be suffficiently worn to cause a few timing snags. I guess that it is a 'standard' model - how do I tell? If I took the plunge and replaced it with one specifically designed for the camshaft, Aldon Autos quote around £230 for a new one.
There are one or two used models on e-Bay for RS2000 Escort, tweaked up Pinto etc, for a fraction of this cost, but it is all a bit of a gamble whether I will end up with any improvement.
Anyone had experience in this direction? Your thoughts would be appreciated.
Cheers
