The car hitches at cruising speed (25-30mph) but idles perfectly. I have reasonably good coils, a new fuel line, rebuilt carb, new sediment bulb, clean gas and still, a hitch. Does anybody have any ideas I can try. I am wondering about the ground from body to frame and from frame to engine. Can there be connections in the ign. switch which can vibrate at higher speed? Need input, must solve, Regards John
Timer - rotor, roller, or flapper -uneven, worn, or weak- maybe???
New one on me John, what does "hitches" mean.
Is this missing, cross firing or plain ole runnin
crappy? or starving, or not breathing? Tight valve
clearances, weak valve springs arcing porceln's,
arcing coils to coil box<<< I know that one, while
adjusting my carb. my wrist laying across my coil
box I got zapped. I had a small cracked insulator.
And yes, ground eng to frame, engine to body. Poor
grounds will drive you, like lightning bad ground
will find a path usually with a melt down. Once I
lost a ground on a truck & got my speeometer cable
melted cause that was the path it found....
"reasonably good coils" may not be your problem but anything but "EXCELLENT " coils can have a hitch, occasionally.
Do you have the luxury of having a nearby friend who owns a good running Model T? If so, a little parts swapping session will be the best and easiest troubleshooting that you can do, because of the numerous possibilities of a hitch, or stutter.
Faulty coil box connections.
Sounds like it fits right in with your Hit and Miss engines, John.
Thank you gentlemen. I shuffled the coils and found #1 and #4 were erradic. This evened it out a great deal.. I will need to improve the coils in future( just learning to rebuild and I have no crank tester) Timer is new, Anderson style and the coil box is lined with synthetic.
