Too far for me I'm afraid, but would have loved to have had a look!

Re: Spitting through HS4 carb
No worries thanks for the thought though.
I bought a new rotor arm and cap through MGOC they did ask what year did I purchase it as the newer ones (programmable 123) are different.

Re: Spitting through HS4 carb
Right, here goes update 1
checked 123 dizzy - NEW cap, pin inside jammed permanently up - not spotted when fitted
so cap U/S
Timing slightly out requires tweaking, however, 123 locked in solid pry bar would not shift it so even bigger pry bar initiated
Air leaking around rear carb manifold
NEW spark plug leads - no 3 arcing on heater valve
123 dizzy replaced with 45 dizzy and re- timed, just as well I had a perfectly good one in the garage spares box
Replaced NEW faulty leads with original working leads - now no arcing
On order- manifold and carb gaskets
Hopefully when everything has been fitted and balanced it should run as it used to - well hopefully better- watch this space....

Re: Spitting through HS4 carb
Hi Steven, thanks for posting back - most folk don't seem to bother, but posting back is what makes a forum valuable
.
Sounds like excellent progress, fingers crossed it leads to a good conclusion! Multiple small problems can be extremely tricky to solve and lead to lots of false trails.

Re: Spitting through HS4 carb
No problem Ian, sometimes by posting solutions to your own difficulties it can help others.
Just frustrating that when you purchase new items they turn out to be faulty,
aide - memoir
Check and recheck all new parts before fitting!!
Will update again when new parts arrive and fitted.

Re: Spitting through HS4 carb
At last a perfect running car 
Now time to own up....
Problem of the air leak turned out to be a washer (don’t ask how it got there as I haven’t a clue!!) behind the heat shield on the lower bolt.. this caused the shield to twist and not seal properly and blow the gasket apart.
