Hi Rich, The different distributors may have different springs, but tho=
se I have seen (don't know which distributors they were, though) had spr=
ings that seemed to me to be pretty robust, similar in gauge to the MGB =
springs. One is typically slack on the pegs, the other on firmly thoug=
h not stretched at all--can be wiggled. Advance curve begins at low rp=
m, which is why you can't do 0 at idle, for example, as advance is alrea=
dy five or six or more degrees.
I don't see how the cam could have jumped---the tensioner is right on =
it from the beginning--does not need to be pumped up with oil pressure t=
o hold the chain. MGB people have been fussing about the slot not being=
milled in the right place, however, so it could be, I suppose, that you=
rs is not properly placed. i did not think to check movement on the lob=
es when I installed mine--just did it per the TD manual and counted (abo=
ut ten times) the links on each side of the marks.Bob

Hi Friends, Update: With timing set to TDC (static) the car starts okay.=
On the timing light, actual timing jumps around quite a bit. Inside the=
distributor, the springs on the centripetal advance don't look right. T=
hey don't look like any advance springs I have ever seen. Small gauge wi=
re and new-looking. Fitment is poor too. I have a set of springs from a=
n E-Type. I'll put them in as a test, just a test. If the idle timing is=
stable, I'll order a correct set for proper advance. Lots of backfiring=
AND carb spitting when opening the throttle, if the timing is tweaked..=
.even a little. Any way the cam timing could have jumped? Thanks for yo=
ur ongoing support. -rick
