Hi, i had my dis. set to almost the lowest point, but then i checked my buddies 2 and his was set higher, so i changed it, i know I should check the timing, but can someone give me pics on how their timing on the dizzy is set, thanks

Something I wrote for the GT4 owners club if it helps.......pretty much the same for any car

....dead easy this one and something you can do in ten mins, the only tools you will need are a timing gun, a 12mm socket, 10" extension bar and a ratchet.

Timing gun £40 from any motor factors



Start off by warming the car up to running temp...indicated by the fans coming on, once you have done this you need to bridge E1 and TE1 as you would when checking for error codes...this disables the ECU`s automatic timing adjustment and gives you a rock steady timing mark.

(Be carefull when bridging E1 & TE1...I accidently touched another connector and blew the ECU fuse. Nit a major issue, but If you have an incorrectly rated fue in it might blow the ECU itself. (ECU fuse should be 15AMP)

Bridging E1 & TE1



Next up connect the Timing gun to the battery Pos and Neg



Then connect the timing gun sensor to spark plug lead number one, at the timing belt side of the engine



Now your ready to check the timing......start the engine.....move to the side of the car and point your timing gun down here. Your looking for the 10 or 0 deg timing marks on the cam belt cover, and the little nick on the cam pulley to line up



There are two ways to proceed from here, either set the timing gun advance to 10 or zero degrees. If you set it to 10 deg, then you need to look at the zero deg mark on the cam belt cover, if you set the timing gun to zero deg then you have to look at the 10deg mark on the timing belt cover.

Make sure you are looking square on to the timing mark so that your line of site is from the timing gun, to the timing mark on the cover, to the centre of the crank pulley....if you dont look square on then it will look as if the timing is further out than it may be, or appear to be wrong when it is in fact spot on.

If the timing isnt spot on (half a degree out is acceptable)then a way of finding out how far out you are is to move the dial of the gun untill the timing mark on the pulley wheel matches up with the timing mark on the cam belt cover.



As you can see from the picture my timing was out by just under 2 degrees.

To adjust the timing you will need to undo these two 12mm bolts(ST205)
But not too much, just enough to allow you to twist the dizzy cap. Twisting with the direction of rotation of the engine retards the timing, against the rotation of the engine advances it,

(Warning - do not run the engine with these bolts loose in any way)

Adjust the timing until you are appy that the engine is running 10deg timing, tighten up the bolts, double check the timing and your done. Unbridge E1 & TE1, remove the timing gun and go for a blast.

As ever, work safe
