My car is a 1927 roadster. I put on a TW Timer, the timer is wired number 1 black 2 red 3 blue 4 green. The wires from the coil box when facing the engine looking towards the steering wheel are number 1 black 2 red 3 blue 4 green. Is this correct? The car still runs very rough, missing and back firing . Any ideas?
It's 1-2-4-3 not 1-2-3-4 at the timer. The coil box can be wired 1234 as long as 3-4 go the correct spark plugs but it's best to wire 1243 at the coil box to, easier to remember which terminal the spark plug wire goes to.
Thank you for your advise, I will again check out the wiring
Too late to edit my reply just do it the way Mark S. shows.
