There is a pretty serious discussion about a torsional damper (rubber front pulley) made in New Zealand on the other site that is way over my head. Maybe some of you engine builders can have a look and comment.

It is used on modern engines to help take out vibration just like your modern engine has simple as that would be a good thing to add if it does not add more issues than it fixes kind of like a lot of drugs. -
If your timing is not overadvanced you will not have any vibration.
There are space issues with the damper, and if you can manage to get one on there, you may have trouble getting a fan belt on there. And since I consider the damper to be a bandaid to the real problem of advance, you will still be hammering at your bearings and pistons.
Feel free to stop by my shop and I can demonstrate this waaay easier than it is to type it!
I can relay this info because we had a customer who insisted he have us install a damper. It was a total disaster. You would never be able to change out a fan belt on the side of the road.
This was years ago before I was more saavy to this timing advance issue, which is one of the nuances of an A, where it is almost impossible to hear ping. Today I would simple tell the guy his timing was all messed up and to forget the damperLast edited by tbirdtbird; 11-24-2017, 11:20 AM.Comment

Now, I know this has been discussed in reference to the FSI distributors and high compression heads, but I need to get just a bit more info on the stock distributor.
I now have in my possession a Snyders 6:1 high compression head and I think since I can't afford a Mitchell OD it will be the next step in the ever changing "Touring Tudor" named Wheezer.

For you real mechanics, what is the rattling, marbles sound that I am getting when climbing long steep hills? I am very reluctant to down shift to second because it is all over until rounding the crest and starting down. I know that I am lugging by keeping the car in 3rd for as long as possible and it rattles. But running at 30mph in second it sounds like a bunch of marbles.

For the first time n 15 years I have a timing hiccup in the blue coupe engine. Using a timing light the timing ( at full advance) is inconsistant by as much as 10 degrees. Could have been there all along, just dont know. Am considering for first time in 40 years of model a'ing installing an electronic timing device. Need input from you guys.
Option 1 is the FSI electronic Kit which...06-02-2019, 11:34 AM -
Ok, a bit of background first.
As some of you know I have been an advocate for the NuRex centrifugal advance and have been using one for 2 years without issue. Well, after reading the threads here about the advance and needs of the HC heads, I decided I would search for an alternate centrifugal advance distributor.
See, the stock engine with the 4.2:1 compression heads are...02-14-2019, 03:57 PM -
Working on the 28 engine and while replacing the timing gear, I found the old one to be one tooth off, the mark on the crank gear is one tooth behind where it should be. I am trying to get it figured out in my head and think this would have been very retarded timing, am I thinking correctly? Seemed to be a lot of carbon around the valves, not sure if this would cause that....03-24-2020, 06:23 PM -
Not long ago Wild Bill Williamson gave us a brainteaser regarding turns of the crank with a multi-cylinder motor. Engine timing is a brainteaser to many.
Let's start a thread and have opinions given about various timing issues.
For example,
1. Does it really matter anyway? Just what is it? Is it more than a pin shoved in a hole?
2. is there such a thing as too advanced...04-02-2018, 05:06 PM -
This engine, with only 4000 miles on it since rebuild, has always overheated and locked up when shut down after overheating, which is usually when driven at 45 or less for 30 minutes or more. (This did not and does not happen when driven under 35 and/or just around town for less than 45 minutes). I thought I had this problem fixed. But apparently not.
Here is the history: On 3/16/14 I...07-01-2017, 01:12 AM -
FSI offers the so-called 'Zipper" dizzy as well as the 'FSI' dizzy. The Zipper looks nearly identical to the stock A dizzy, but has a fixed advance total of 28°. The springs can be changed to alter the shape of the curve, but the total cannot be changed. It is most suited, IMO, for a stock motor with a 4.2 head. In actuality, if you are running a stock 4.2 head you will not have to change anything...10-26-2017, 10:42 AM
