Would like any ideas on my problem with my speedster. When I get rolling down the road at about 40 the engine sounds like it's cutting out.At low speeds runs smooth as glass.
Ground wire from distributor to block installed? I have found that without an external ground you can have a miss.
What point gap do you have?
Does the distributor shaft bearings have ANY slop?
Is the point cam rough at all? The surface should feel smooth to the touch
Possible.The only modern T distributor l have experience with is a Bosch from a Beetle.Those points are commonly available.
Make sure your upper bushing has no wear.If it does have some,open up your gap a little.
One of my Model A's was only happy when l put two springs on the points to stiffen them.
But,again,that A roadster had a warmed up,bored out,presicion balanced engine,so l really ran hell out of it.
Sorry to be repetitive.Slowpoke and had interuption.
That's a lot of great info! The top of the distributor does have a loose feel to it. I will check the ground and the point cam. It happened on the last day of the winter tour. ty.
P.S. and check the point gap. ty
Very important! Make sure you have an external ground wire as Mike Bender posted. My car would miss at times until I added the ground wire. The Texas T parts 009 distributor was loose fitting where the distributor rotated (Advance/Retard) and did not provide a good ground connection. The added ground wire is a simple fix.
I was helping to time an older Ford 401 Workmaster tractor that missed really bad at higher RPMs. Turns out that the spring clip retainer that holds the rotor to the shaft was missing. The rotor was wobbling around at higher RPMs, changing the timing because of the loose fit.
Also check that the coil is wired properly, wire to points on negative side of coil.
