My Manual is not so clear about this adjustment. What is the best idle for this adjustment? Should it be done with the selector on P or N? Have I just to align the marks on the flywheel? What is exactly the signification from graduation on the octane selector? Thanks Roland 54 Bel Air 4D sedan 54 4 speed. That is, bump the starter till the 'bb' on the flywheel lines up with the pointer, then adjust the distributor so that the rotor is pointing toward the spark plug going to the 1 piston and the points are 'just opening'.
An ohm meter can help show where the contacts are just opening. I believe most people don't disconnect the vacuum advance, the idea being that the distributor will not be advanced at all at idle. Your idle RPM is not so important when setting timing unless it's really high, or so low the motor stalls. You fine-tune the idle after setting the timing.
I think the manual specs rpm in D, and rpm in P. However a lot of people prefer a higher idle rpm. Has this engine been run at all yet? If not, you need to be careful and break in the cam correctly when you get the motor running. Roland 54 Bel Air 4D sedan 54 4 speed. Solid lifers do need to be adjusted regularly and hydraulic lifers can be maladjusted at some point in the past to where the valves don't properly close.
Robert May Fat? Eat less and you will get thinner! As soon as the speed is increased--throtle plate opened--the vacuum advance will begin to advance the timing.
How to Set Ignition Point Gap
The mark is a steel ball in the fly wheel. Set so steel ball and pointer line up.Its a '51 Chevy with original straight six. It doesn't have a clamp and bolt like im use to. The vacuum advance is at the base of the distributor and if you try to turn the dist. Any advice would be appreciated. Chevy had a ball on the flywheel that was the timeing mark, and it also had points. Points could be adjusted with a feeler gauge, if you know the thickness, about. A dwell meter is better, get the dwell and set it to the specificed dwell.
Then set the timing afterwards, or your timing will be off. The ball is the timing mark, and it is located on the flywheel of the engine. A hole is opened to allow seeing the ball on the flywheel. You will need a timing light to set the timing at the specified rpm. This below will give you some idea, but you need the specs on the points, so the library has these books by Motor hopefully they do.
The vacuum is the lower part of the dist, you need to undo the clamp under it to move the timing. But first you have to set the dist back to original or close. Then set the timing at btdc with the vacuum off at somewhere around rpm. You need a dwell meter to set the points way before you set the timing. Hope something helps. YES HAHA a ford man knows good stuff haha but mark the timing mark when its not running its a bit easyer im just bsing ,but yea he got it rite just plug the vacume hise off the manifold ir carb plate that goes to the distribitor as well see if you might have a few cracked vac.

InGM decided to use the in several of its automobiles that were going to have the new Powerglide automatic transmission.
Inall Chevy engines that were used with Powerglide transmissions were upgraded with a fully pressurized lubrication system as well as hydraulic lifters. If a car buyer chose a manual transmission then they received the older engine design with solid lifters. One interesting fact about the inline 6 is that it was the engine that was used in the first Corvettes that were produced in and ran up through This same engine was also used in GM trucks from to In this long lived engine was officially dropped from the GM production line and replaced by the all new Chevy I6.

Many of the old classic and muscle cars used the mechanical ignition points, which still have to be set according to manufacturer's specifications.
High-energy ignition has eventually replaced the old standard design, but for those who still own such vehicles, the need to replace the points and condenser remains one of the many necessary chores. A few simple tools and some knowledge can make the chore of replacing the points swift and easy.
Place the vehicle in park or neutral with the emergency brake set. Raise the hood and disconnect the negative battery terminal with an end wrench. Locate the distributor at the rear of the engine next to the firewall.
How to Set Points on a Small Block Chevy
Use a slot screwdriver to turn the two distributor cap mounting screws 90 degrees out until they release. Pull the distributor cap off and set it aside in the engine compartment without removing the wires.
Pull the distributor rotor straight up and off. In the case of a round rotor cap that has two screws, remove the screws with the slot screwdriver and lift off the rotor.
Don't lose the rotor mounting screws. Remove the small screws that hold the old points to the distributor base.
Detach the points wire that connects to the small connector post. The points wire will either pull up from spring tension, or a screw will hold it in place.
Only loosen the screw to remove the wire. Remove the condenser wire in the same fashion. Remove the screw holding the condenser to the distributor base. Discard the old points and condenser. Place the new condenser and points on the distributor base, aligning their positions with their small mounting guides. The points will have a small pin that fits into a pivot hole in the distributor.Most classic cars do not have electronic distributors, but rather rely on a set of points to trigger the ignition system.

Adjustment of the ignition of engine Discussion in ' ' started by wokriApr 30, Joined: Jul 14, Messages: Location: Germany. Hello, I have a question: On the fly wheel on my truck are two signs, a steel ball and a triangle.
Which one is the right one to adjust the ignition? I have use until today the triangle with the result that the engine is running but not good. Then I have a second question: I filled up the oil until its up to the full mark. The oil pump needs a few turnings of the starter until the oil gauge shows pessure. Could it be the oil is running out of the pump if the pump doen't work? Last edited: Apr 30, Thanks Hello big Jim, thanks! Cehck to ensure you have no vacuum to the dizzy when it is idling!
Nate Ooh, sounds good Nate. I do the same on the next weekend because my engine is runnig but not perfect. VolkerMay 5, Engine is running!
Hello, yesterday late evening a freind of mine and me get the engine running. Not perfectly but the engine runs. I was a drama! To line the distributor dis with oil pump was easier as I thought.Gain extra benefits by becoming a Supporting Member Click here find out how!

The carb is just a rebuilt Rochester 2bbl — same as original. I ran the motor for about 20 minutes to seat the rings and then changed the oil.
I did not have a dwell meter until yesterday, so I just set my point gap to spec 0. Like I said, the engine ran pretty good, but there is a slight stumble, so I thought I should break down and buy a dwell meter to verify my dwell and then readjust timing if needed. I hooked the dwell meter up last night and was shocked to see a reading of 15 degrees. I know dwell should be around I had to stop and make sure I was reading the gauge correctly since this one will read 6cyl, 8cly, and technically 4cly you just double the 8 cyl reading.
I was reading it correctly, so I started to adjust the dwell by turning the set screw in the distributor. As I turned it clockwise, the engine starts to run poorly. I stopped at about 25 degrees dwell because I thought it was going to die on me and checked the timing. The timing went all the way down to about 8 degrees ATDC. Am I doing this wrong?
