I changed my points to electric and the timing was off. So me and my dad had a go at the timing. Had a look for timing markings and all we could see is a arrow.

The car is running pretty rough, we have checked all vacuum pipes but it still runs bad.

We even put the old points back on and it'd still horrible to drive.

Im really losing my patience with this car, any help would be great.

Did it have a misfire before you changed to electronic ignition?

re set the timing, piston no1(radiator side of engine) at tdc, then put your electronic dizzy in with the rotor arm at roughly 1 oclock position, then try start the car(rotate the distributor body slowly until the car starts), then increase the idle to 1000 rpm, untill you hear a slight pinking, then retard the dizzy slightly.  you might need to fine tune the timing by rotating the dizzy if the car is hesitant under load.

It was fine before the electric ignition.

is the timing mark an arrow? its a 1982 city!

 

anyone shed some light on this? I'm desperate! 

[shaw26]

compression readings were

 

174 130 130 116

[lrostoke]

that's not good, regardless of timing those figures and the last 3 are really low.

 

could be ring problems, or if your lucky valves need adjusting

 

the arrow is the timing marker, and on the pulley should be a notch

 

In fact its a big arrow, with about 4 or 5 smaller peaks

 

did you have throttle open as you took each reading

yeah I noticed the big arrow. So where do I go from here?

[shaw26]

what should the readings be roughly? 

[carbon]

compression readings were

 

174 130 130 116

 

Compression readings should all be within 5-10 psi.

 

Did you have all of the plugs out and the engine warm when doing the tests? Also was the battery still spinning the motor over at the same speed on the last reading as the first one - this 116 is really low.

[lrostoke]

you 175 is about right, then they just get worse..Like carbon says was the battery still strong for each test

[shaw26]

No one at a time. I did the same for each plug turned it over for 5 seconds

[shaw26]

It's a brand new battery

[ejs-1995]

To do a compression test i was always told all plugs should be removed and it should be wide open throttle. Carry out the test again then put a dab of oil down the bores and see what happens

[shaw26]

what I dont understand is that the misfire only happened when I installed the electric ignition and when we put the points back on it was still misfiring.
