Can someone tell me how to lock the advance? Yaw's article said very little and gave no details about how. Anyone have any details? Thanks.

Inside the distributer there are weights and springs that mechanically advance the

timing. Then there are the two vacuum advance (one leading, one trailing) that

change advance based on vacuum.



To lock the advance, you would need to remove the WHOLE distributer,

completely disassemble the Whole distributer,

remove the weights and springs,

then secure the two halves of the distributer shaft together by either

drilling, threading, and screwing them together, or welding the parts together.



Then re-assemble, re-install, and re-time the distributer.



Oh, and don't forget to remove the vacuum lines too. https://www.nopistons.com/forums/pub...DIR#>/wink.png

why does timing have to be such a beioch what if you start the car and its way off and you get a nice ping and then there goes your engine https://www.nopistons.com/forums/pub...O_DIR#>/11.gif so how do you know wheather or not your timing is way off if your installing a new distributer. for ex: i'm swapping in a gsl-se motor on saturday and i doesn't have a dizzy so i have to use the one from my 12a and i heard that the "timing curves" are different so how do i set it before handso i can just start it up to then be able to set the timing with out blowing my $hit up?

Just align the circular mark on dist. gear with the mark on the dist. housing.



Make sure the crank (eccentric) shaft timing marks are @ TDC, drop in the dist.

Install the dist. hold down bolt finger tight in the middle of the slot.



When you're ready to time, it should be close enough to start the motor.



As far as PINGs, it won't ping at idle.

2 reasons; 1, the combustion pressures are lower at idle.

2, the air/fuel mix is being diluted by the exhaust gasses being passed from

the exhaust to the intake through the channel (combustion "chamber") in the

face of the rotor.



So, if you start the motor and time it before revving it, no worries! https://www.nopistons.com/forums/pub...#>/biggrin.png

Good Morning SmogFighter;

Since we are on this subject of Timming issues.

I gots one for you.



When you line up the leading mark on the pulley and turn it 1 revolution the Disti Rotor is facing the opposite direction i.e. Arrow on the Rotor Cap.

There is a dot on the top of the shaft also. So when do you know that you are set up correctly besides linning the Bottom Gear https://www.nopistons.com/forums/pub...R#>/unsure.png

Anyhew.

Linning up Bottom Gear with Dimmple/Talley Mark if you turn the Pulley 1 more revolution you end up with it facing the opposite direction???

Any clue which is the right way to start from scratch besides your great info above.

Thanks

Hey Luis;

Trust me! If you are looking at the Rotor Cap and line up the Pulley to the First Mark i.e. Leading and turn the Pulley one more Revolution you will notice that the arrow on the Rotor is facing the opposite direction. The Tally Marks & the Bottom Disti Gear will be also facing the other direction??? Don't Figure!!!

I have 3 Distributors and they all do the same thing.

Still waiting on My RB Holley to get back. I have a feeling that they are going to sit on the one that I sent back last Monday until they get tired of me calling them. Where the F@#%& is my Carb.

Have a good Sunday.
