pinto timing help its doing my head in
Hi all the engine was running fine then had the head skimmed and added a new kent fr32 cam the trouble is ive positioned the crank pulley on the 1st
marker out of the 5 that are on the pulley which i presume is tdc as piston 1 is at the top thats by having a long extension bar in pot number 1. cam
pulley is pointing at the marker on the cylinder head. the rotor arm is pointing between pots 4 and 1 on the dizzy cap with what i read it should be
on pot number 1 not between the two of them. i never touched the dizzy only the head. any idea's what im doing wrong. thanks

Hi, the dizzy is driven off the aux pulley you need to turn that to get the dizzy pointing at no1 plug lead then set your static timing once you have
the belt back on hope this makes sense
Ray
ps tdc is the deeper line on the crank pulley
and it sounds like the aux pulley moved while you had the belt off

thanks for that i just found a diagram that made sense. the only thing is that all the marks on the pulley are the same i only put it on the first one
as it had a bit of tipex on it. any idea which is the best mark to put it on? cheers

Sounds right to me, the bottom pully should be on the first mark to the left hand side as you look at it. (i.e. if it was a clock, its the first mark
that the second hand would hit)?
Check dizzy.

the one with tipex on will be 6 or 8 degrees btdc assuming whoever put the tipex on was doing it correctly to use a normal timing light tdc will be
further round approx 3/8" set the cam up to tdc then check the points open just as you come round to the tipex mark if you put the ignition on
you should see the points spark as they open.

thanks raylee29
thanks for that as i was putting it on the first mark to the left. theres no points as i replaced them with a little electronic ignition that sits in
the dizzy, not played with timing and dizzies for over 20 years. hopefully ill have it sorted out tomorrow thanks to you lot.

some times the distributor has a mark on it too. If you remove the (assuming its a brown Bosch type cap) distributor cap and look carefully at the top
edge of the distributor body (on which the cap sits) you should find that there is one little indent. When the cam and bottom pulleys are alligned
then the rotor arm should also be pointing at this indent when looked at from above.

No the timing trick doesn't work with those, Just put a tipex line on the distributor body under No1 plug lead, then remove cap and with the
other timing marks aligned (with belt off) turn the distributor pulley until the rotor points at the tipex mark, or (with belt on) loosen distributor
clamp pinch bolt (and timing marks alligned) and turn body until rotor points at line then retighten pinch bolt. JD apart from timing light setting.
