like an idiot i must had my head up my a## i took out my distributor w/ot marking the location of my rotor...i know firing order is 1-5-3-6-2-4....so my question is when i get #1 tdc where should my rotor be pointing? p.s. i did mark where the vacuume was pointing on the distributor

Point it just past the number 4 , when you slide it in it should be right

MonteAZBB70 · 01-21-2010, 07:30 PM

Number one should be TDC on the compression stroke. Take out #1 spark plug and put your finger over the hole. You should feel air trying to escape from the hole as you rotate the engine in the correct direction. As the piston gets very close to TDC, like a few degrees before, the rotor should point to the tower on the distributor cap with #1 plug wire attached. That should get you close enough to get it running and use a timing light.

silvervic99stang · 01-21-2010, 08:25 PM

right now i have it pointing to number one piston... i know the piston is all the way tdc but no idea if its compression... i have my wife bump it but she hold the key too long lol ill just have to wait till tomorrow to get a buddy to help me with it...

"the rotor should point to the tower on the distributor cap with #1 plug wire attached".

do you mean the rotor should be pointing towards number 1 on the cap if it was on...that is also pointing towards #1 cylinder am i right?

Yes. You might even consider setting the cap on the distributor and drawing a line with a Sharpie on the base of the distributor that corresponds with #1 plug wire. That way when you take the cap off to watch the rotor, you'll still be able to tell when it lines up correctly.

i got it.... but now i am not getting no fuel...i unhooked my fuel line and turned the motor over and no fuel out of the line so i am assuming bad pump....

62gmc910 · 01-23-2010, 10:51 PM

could be pump or one of the 44 year old fuel lines you may as well change them now

silvervic99stang · 01-23-2010, 11:49 PM

yeah im going to work on it some more tomorrow...let yall know how it goes thanks for all the help...

silvervic99stang · 01-24-2010, 05:15 PM

ok i got it running but im needing to advance it some more and the vacuum is already hitting the block.... what i'm thinking is when i set TDC it was not all the way...is that possible? when i try to gas it it backfires thru the carb...is that a sign of not in time...it idles ok but i have to have half choke, i also got that reman...distributor and one of the threads is striped out so i have to remove it again and return it and get another one so my cap does not tighten down well...could that also be a problem? any info will be helpful thanks..

That was why I said to point the rotor just past the number 4 in the first answer to your question . as the distributor slides on the helical gear it retards the timing . Then a new set of instructions showed up . So spin the engine to about 9 degrees BTDC no 1 pop the dist cap mark where it points when the distributor is in the position you want it. turn the engine backwards until the rotor is just before no 1 on cap . pull the distributor slowly with out moving the shaft once it is free. now turn the engine back to 9 decrees and reinsert the distributor. this way the oil pump drive is lined up .

silvervic99stang · 01-24-2010, 08:06 PM

ok thanks...

62gmc910 · 01-24-2010, 10:25 PM

I missed the part where you have to get a different distributor . it should be the same basic proceedure. where you turn the distributor so that no.1 on the cap is almost straight ahead . by rotating the engine CCW until the rotor points to the no.1 position on the cap you locate the oil pump drive so that the distributor will slide in where you want it . carefully pull the distributor out noting how much the rotor turns towards the no 4 position on the cap. probbably 1/2 way between 4 and 1 . now with the distributor out turn the engine CW to about 9 degrees or 5 if you are a low altitude. when you get your replacement dist. point the rotor the same as it was on the one you took out (should be between 4 and 1 cap position . drop it in hook it up and it should be within a couple of degrees.
Is this a little clearer

silvervic99stang · 01-27-2010, 09:05 PM

how many degree is each mark? if they are 2, i got it set at 4.... I need to buy a new carb. for it. It leaks and it sputters when i try to accelerate, does anyone now of anyone that sells stock carb. thanks for all the help....
