Re: Full Front Suspension Rebuild

Contact Travis at A-Springs.com. American made and I'm pretty sure he supplies the vendors. He'll tell you how to get it ready to install and send a page of instructions. I just bought and installed...

Re: Wheel Washers

I re-torque my lug nuts every 2 - 300 hundred miles, or whenever I'm going to be out running at higher speeds for a significant length of time. I've waited too long in the past and lost a lug nut...

Re: Front end shimmy

I read somewhere recently that proper setting of the toe-in can sometimes resolve shimmy, even if other parts are worn. Not sure about the braking type shimmy, but would be worth a try if the toe-in...

Re: wont fire

I believe this picture originated from Tom Wesenberg, but I copied (control/c) it from a thread on this forum called "Rotor Position Question" and pasted it into the post.

Re: Can't get engine started after changing timing gear

I congratulate you on your success. I like your approach with a new thread for the sputtering.

Re: 1929 double a won't start, help

Dan, JG61, the model B engine has a different pattern to the water pump bolts. The A is mounted with 4 bolts and the B engine has 3. A picture of the water pump and its mounting will tell the tale on...

Re: 1929 double a won't start, help

I suggest cleaning the contact pins on the distributor upper body. The Nu Rex wrench should get you back in the game. I predict that: Once you see the proper points to cam relationship from a...

Re: 1929 double a won't start, help

Dan, I'll remind you that the coil primary circuit's magnetic field collapses when the points open. This instantly induces a high voltage/pressure but low amperage (milliamp) current that fires (is...

Re: Darned reproduction parts!

Bill, I may be confused, but I thought the GAV supplied the Cap jet, not the Main jet. On my Zenith carb the GAV has a direct path to the Cap jet. But some Zeniths have the GAV path to the Secondary...

Re: 1929 double a won't start, help

Re: 1929 double a won't start, help

Re: 1929 double a won't start, help

Danny, I had trouble with my car that was very similar. It was new to me too. Although I knew a bit about A's from my youth, 50 years ago.
