Triumph TR6 - Timing

I was wondering if anyone has experienced the following regarding setting timing.

My distributor is rotated clockwise until the point that the tach cable is at its limit...pushing my luck and rotating a tad more doesnt appear to gain any additional idle smoothness or rpm (they seem fine at the point before this limit) but does bind the cable nicely :-(
Why would i need to rotate so far for the timing...cam chain off by a few teeth? is there any way to adjust for this rotation elsewhere with pulling off the front?

Thanks

Hi Bob,
Your distributor may be installed 180 degrees out.
Check the archives for further discussions on this topic. I had the same problem.
Hope this helps,

Hi Bob,
I think your dist is fine..when I got my car the dist was advanced all the way like yours by the previous owner and it will cause your tach cable to break inside ( ask me how I know )...just back it off till there is no strain on the cable...your idle will drop so you'll have to bring it back up with your idle screw..that'll probably fix your back firing as well as running a bit cooler...the more the timing is advanced the hotter the engine runs.
We can check it with my light when you come over

Bob,

Try the folloeing:

1 rotate engine until timming mark is lined up
with the pointer, with cylinder #1 on the firing
stroke at tdc. the distrib.rotor will, if
correct, point to the spark plug terminal for
#1 cylinder.

2 undo the clamp bolt holding the distrib. in
place, pull PARTIALLY out, KEEPING THE ROTOR
IN THE SAME RELATIVE POSITION TO THE DISTRIB.
BODY, [the distrib AND roter will rotate a bit as
you do this.]

3 when the drive is free from the cam gear,
rotate the distrib/roter assembly approx,30
degrees or so COUNTER CLOCKWISE, then
replace the distrib./rotor back into
engagement with the camdrive. it will want
to rotate a bit as you do this

4 you now have the rotor pointing to plug
#1, with the distrib. body rotated back to a
more appropriate position,

5 re time [fine tune] the distrib. in the normal
way, tighten the clamp bolt...go for a drive!!

GOOD LUCK

Bob,

I should have suggested that you try the FOLLOWING...........

I hope my mechanics prove to be better than my spelling.

It sounds complicated,..IT IS NOT, we can phone discuss more if you want a "walk through"

Hi Bob I had the exact same problem I simply moved the dist clockwise a bit and then moved all my ignition wires over one spot. very fast and my dist cable is perfect call me if you need further instructions PS the cars almost done!

Very good. The definitive answer for Bob. Might I be so bold as to add one wee point ( kind of an obvious point but still important). You will know you are on firing stroke when both valves are closed when #1 is at TDC.

John, that is rather an extreme move.
