The engine did receive some work in 1988 where the pistons and cylinders were changed and an S cam and timing adopted. I haven't established exactly the specification of the engine although this is probably not relevant to the problem. It may however be relevant when comparing Weber jetting where my engine may need something different from the standard 2,200 T engine.

So the Webers are the originals to the T? Any mods to the Webers? What about mods to the heads and distributor? If you change one thing on these motors, other things need to be adapted to match.

Post the details of the Webers. Venturi sizes, jets, etc.

There is a big step from T to S cams.
