Timing

(1/2) > >>

Yoshi:
how do you adjust the timing accurately with no strobe light thingy and no access to a garage? trying this tomorrow now you see :D

Rich_P:
On a 2.25 Litre Petrol, position the engine to top dead centre by manually cranking it round slowly.  Then adjust the distributor accordingly in getting the points correctly set up.  It shouldn't be far out then, and just advance or retard it slightly by the adjuster on the dizzy.

Devon-Rover:
Hi. what engine is it, late or early?

Yoshi:
we think its possibly the 5 bearing, basically i have got the point of doing the engine timing, but i have had a suggestion made to me about something to do with a 12v bulb, but the person couldnt remember quite how the wiring for that went, he said basically you move the dizzy round until the light comes on then move it back ever so slightly??

does that sound about right?

Devon-Rover:
ok then so were looking at a 8:1 compression with a later dizzy.

It might be easier to turn the engine over without the spark plugs in.

On the front crank pully there will be a Little dimple cut into the top edge of the engine side of the V of the bottom pulley. marking TDC. Next to the pulley will be a marker with three little pointers. looking at the engine you will want the LH side marker. This is TDC for the timing.

Mark the setting of the dizzy on the block so when you twist it you can revers the procedure if it goes pear shaped.

Take the cap off and the rotorarm and in the case of the duceiller dizzy the little round plastic guard bit.

Next to set the points gap the 25 thou using a feeler guage.

Now you can losen the clamp on the distributor and turning it in a anticlockwise rotation this is to get the points heel off  the distributor central cam because you are now going to slowly move it forward again to get the points to just start to open as the heel of the points climbs the cam. Then you lock the distributor down as your timing should be about right.

If the timing is a little advanced it will not be a problem. If you can hear the engine pinkng on accelration then you'll need to retard the timing a wee bit by turning the Dizzy clockwise a bit.
