when i hook to T1 spark wire the vacuum valve doesn't change trailing timing... when i hook it to the L1 wire it does change the leading timing..

Can my distributor be in wrong?? what is going on? the car seems to run fine a little hesitation but other than that ok.

I went to time my car today and found it was about 7-10 degrees retarded so i went through the process and am wondering whats going on I have a copy of the factory service manual and followed its diagrams but something seems screwy
the wires are correct the rotor button is correct "keyed"
Is it possible to have the two connectors going to the wrong ignitors?

I also just replaced the factory type wires with a set of accel magnecor type 8.8 mm wires
I have read that the timing gun can pick up on the wrong signal but the gun seems to be working fine.

it just seems that leading and trailing sparks are switched..

 

Figured it out with some help.. Leading and trailing coil wire were switched.
