'57 Beetle front wheel shimmy and engine miss

[Mapes]

I have a restored matching numbers '57 Beetle. I bought the car two years ago and have two problems I would like some help with:

1. I have radial tires on all four wheels. When I hit a pothole at about 30 MPH, I get a bad wheel shake (shimmy) from the two front tires. If I hit the brakes hard, and slow down, the shake (shimmy) stops. Any ideas what needs to be fixed?

2. When I drive the car on the highway at 60 MPH it runs great until about 30 minutes into the drive at which time it develops a bad miss. I can't tell if the miss is fuel or electrical related. If I pull of the road, stop, and then proceed again up to 60 MPH, it runs fine for another 30 minutes after which time the miss reappears. Any ideas on what my problem might be?

Any help with suggestions for fixes to my two problems would be GREATLY appreciated!!!

1. You need to adjust the link pins in your front suspension. It is likely that they won't tighten any further, in which case you need to do some front suspension repairs. Your link pins and their bushings and shims are likely shot, it is a 60 year old car after all! The king pins may be loose too. This work isn't very expensive if you take it disassemble and reassemble it yourself and just have the shop rebuild the steering knuckles.

2. It sounds electrical. A single cylinder miss could be an intake manifold leak at one end, but most often when the miss is clearly a single cylinder it is ignition related. Some ignition issues that frequently cause a warm miss in a single cylinder are a bad plug, a bad plug wire resistor end, or a bad plug wire. These are not the only possible causes, but generally where I start testing.
