Re: Front left wheel play
Synchro, please explain further. Should the lock bolt be tightened with a wrench only? Are the lock bolts not softer than the forged axle? At least one curious mind wants to know?

Re: Nu Rex ignition switch
Tiger2, post 19:
The diagram in post 13 is nicely drawn. It is easily understood by experienced Model A persons. It is lacking a few details that will be needed by the beginner Model A person that...

Re: Nu Rex ignition switch
Guyz, Katy's diagram in post 13 shows the power side of the coil as the - neg and the distributor / points side as + pos. It also implies a 12v system. Unless he has a 12v positive ground system, his...

Re: Misfire mystery
Fairlane, I don't hear the same puff, puffing that our coupe has in your second video. You are likely correct about the fan blade, but to be certain, perhaps holding a piece of cardboard between the...

Re: Misfire mystery
You can pinch the hose on the gauge between two fingers and a thumb, as I remember. Like pinching a garden hose and then release the pinch a bit to smooth out the gauge. I've read that a 4 cylinder...

Re: Misfire mystery
Our coupe's puffing is much more noticeable. Is your car's puffing at the tail pipe more pronounced in person than on the video?
Is your vacuum gauge dampened?
The idle seems a bit fast. I...

Re: Condenser Capacity
Nice thread guyz. I experienced my first point/condenser failure a couple months ago. The condenser, a modern type upper plate, was over two years old and had about 13000 miles on it. I have a simple...

Re: Misfire mystery
The Nu Rex one is different and does not require removing the distributor. Your light weight cable probably unscrewed from the distributor without removing the distributor from the engine. If the car...

Re: Misfire mystery
There are ways to use jumper wires to temporarily bypass virtually all of the normal ignition circuit wires. The vendors sell a jumper for bypassing the large cable from the coil + to and through the...

Re: Misfire mystery
X2 on congrats. Your post describes a failed ignition cable. I also like your theory. The post implies that the misfire condition, which you have been looking for, is now gone.
I'm hoping this is...
