Model T Ford Forum: Forum 2015: Must be the timing ?
Top of pagePrevious messageNext messageBottom of page Link to this message  By Randy Glowacki on Monday, May 25, 2015 - 02:29 pm:

Hi,
I filled the tank with new gas, a new TW timer. I tried to set the timing with the TW indicater . The car started fine but ran very rough, when I switched to mag it almost stalled. Miss firing and back firing all the time.
Any ideas ?

Did the car have this problem before you changed the timer?

Stephen

I think you might have gotten a couple wires mixed up at the timer when switching it. Easy to do that.

Sounds like two cylinders are hooked up criss-crossed. Easy enough to trace - slowly turn the crank and listen for each coil to buzz. Then test each plug with a screwdriver to the head, to see which one is firing.

Caution -- Don't let a coil buzz for very long. They get hot.

The firing order is 1 - 2 - 4 - 3.

Or you have the through hole on the cam shaft and your turned the brush assembly 180 but I don't think it would even start, check your wires on the timer.

Thanks everyone,
Stephen , I did not have this problem before I switched the timer. I will have to check if I crossed something up.

Timer is wired 1243 but remember it is counter clockwise.

Check the insides of the timer case very carefully. On my TW timer there was a thin, curly scrap of metal (similar to a metal lathe shaving) that lodged between a timer segment and the case causing a short. I don't know if this was in the timer when new or possibly a shaving of the new brush while "bedding in".

There is an old adage that seems to apply to everything I do and maybe it works here too. When something goes wrong, look at what you did last. I usually find the fix within the last thing I "fixed".
