when making timing adjustments is it best to loosen the bolt holding the whole distributor housing down and then turn the whole hosuing or loosen the phillips head screw and just turn the upper housing/cap only?

i would think either would work and not be any different as long as timing light shows the correct idle timing.

looks like maybe the phillips head screw way allows for a quicker adjustment.

Re: distributor timing adjustment with whole dist turned or the

i don't think you can turn just the top...the whole thing twist...you need to loosen the 2 10mm bolts holdin the dist on...the wholes are oval and allow for the movement.

Re: distributor timing adjustment with whole dist turned or the

i have 1 phillips head screw that when loosened allows me to move the top portion of the distributor housing for timing adjustments. as i went out and re-looked at it, the phillips head is not really at the base of the cap, but further down the base and the whole upper section turns. there is a timing tab also on the other side under the dist cap(radiator side) that has timing marks also and you can basically set the timing without the engine running this way. i thought it was kinda weird that the crank pulley has its own timing tab next to it, and also the distributor itself has another timing tab below the base of the cap.

it looks like there are 2 bolts at the very base of it that holds the whole dist to the block but i dont loosen these. maybe what i am loosening is the way to do it and im just not used to these types.

i have it idling at 900 rpm now, but the vacuum advance is already kicking in with around 17 degrees at idle. if i unhook the vacuum line while its running the advance drops back down to 10 degrees.

I loosen the base w/ 1-10mm.

Any way you get your correct timing is OK BUT most people leave the 8mm's in the middle of thier adjustment. If it is really necessary go ahead and loosen the 8mm's. NormK.

so most people just loosen the phillips head screw for timing then.
