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?
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.
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".
Mark and John,
Thank you, I will check this out.
Randy you ain't got it solved yet!?! Definitely come back and let us know if you fixed it! I always like to know how things turned out for folks.
Here's the color version.
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".
Seth, I will try and work on it this weekend and keep you posted . Steve, thanks for the color rendition, it helps to clear things up
