Dead Cylinder

[Lucia289]

Appreciate this is an old thread but wanted to pass
On my thanks for helping sorting a dead cylinder running 48 IDAs problem.
Did all the obvious spark ,leads , plugs rotar and caps. Determined issue was fuel so cleaned idle jets and still cylinder would not fire 🔥!!😤
Solution : turned out idle jet on carb corresponding with dead cylinder by 1/4 turn and bingo !!

Thank you again

- Have you tried using the air bypass to overcome the bent shaft (if there is one?) to overcome the balancing problem?

- Have you checked tha corresponding valve/lobe/lift to see if it's correct on the ctlinder in question? (I once had a wrecked camshaft with some of the lobes gone south- very hard, indeed, to get the carbs balanced.)

- In terms of a linkage creating troble: Do you use 2 (one at each bank) idle set screws and a return spring?
