I have a timing advance plate here on my desk... the plan is to cut one
loop off of the springs in both of the mechanical advance circuits to
alleviate some detonation I am theoretically attributing to spring fatigue.
Actually, why don't I get off my ass and measure that with a timing light
first.
Anyway, as I think it will likely be this anyway, my question is does
anyone have any suggestions for cutting a small advance spring without
wrecking a tool? I KNOW this material will screw up my cutting dikes and
I'd like to not do that. Thanks in advance.

A small spring won't hurt regular sized dikes - tho it might nick the
miniature ones.
Or you can CAREFULLY use a bench grinder to cut away a portion of the
loop, then bend it until it snaps.
I would just cut it using full sized dikes.

Mike, before you cut anything, go to your nearest Napa Auto Parts Store and
see if you can purchase a distributor advance repair kit. If I remember
right, inside the kit are several different sizes and strengths of springs.
When the dumb kid at the counter asks you for what car, tell him it's a 1970
Chevy El Camino with the high output 350. I'm sure there are other kits out
there.

OA.
I know they don't take food stamps at the parts store, but have you
considered buying new springs?

If they issue a food stamp with a caprese on it, let me know. I want to put
it on my Christmas cards.
As for new springs, they don't sell them. The field replaceable unit on
this is the entire advance mechanism which is a shame since it appears to
be easily rebuildable.

Thanks John... I had wrecked a really nice set of dikes cutting a clutch
cable on some guy's bike I came across broken down in the woods. Made a
make shift clutch lever for him. I assumed spring steel to be as hard, so I
was just leery to wreck a nice pair again. I guess I can give this a try..
thanks!

Mike, you should replace the worn springs with original equipment,
replacement springs.

Use a dremel with abrasive or diamond cutting disk. If the springs
have squared and ground ends, you will not be able to duplicate
them easily.

Thanks Chris.. they only sell the whole mechanism for $80. I would like to
do just the springs but can't get them. I could probably hit NAPA and buy
springs and guess.. but that is too much work.
The plan is this... if one loop is not enough, I'll remove a little mass
from the weights to dial it in. If it's too much, I'll add a little mass.
PITA but 80 bucks is 80 bucks.

Hmmmm.... the idea that this is some place with lots of bins with springs
in them. I like that. Let me try this NAPA thing if the timing light
reveals too much advance.

A fixed up El Camino is on my list of possibles to replace the Lex.
Hey.. you're a Jag guy. Let me ask. I need the cockpit to be tall so I can
get in and out with this hosed up spine, but I also want something with
some balls and which is reliable. Jag make anything that'd fit this bill?

I remember way back to the hot rod days of the 60s. There used to be
guys who would "curve" your distributor for a nominal fee. That meant
changing the springs then running the distributor in the spinning
machine to check the advance. Get a hot rod mag or look on the 'net. OF >> Stay informed about: Cutting a spring? |

don't springs sag over time??
is this spring getting pulled or pushed?
if it's getting pulled why not tie a couple
of the loops of the spring together with a
bit of fine wire (like the kind to wind coils
of a speaker) then go test the shorter spring
to see if thesmaller spring is better BEFORE
you hack the thing up.
if it's getting pushed put a spacer in there.
