Chaps
I have been trying to set up my 2wd cossy engine but do not seem to be able to. I set the timing maks on the cam pulleys to face each other then set the crank pulley to top dead centre and then set the distributer arm to the scribed mark on distributer body. When I crank it over and back to top dead centre the cam pulleys and the crank pulley go back to top dead centre but the distributer arm does not . The pulley on the auxiliary shaft has no timing mark like on the cams, I think its a pinto pulley but I have asked and pinto and cossey have the same pulley or so I have been told
Any ideas why I cant time it up.

Something has to be slipping for this to happen, or one of the pulleys is not the correct one(teeth).
It is fixed mechanically so unless belt slipping pulley has to be wrong on auxillary shaft.
Easy way to tell is to count the teeth.
Crank pulley will have EXACTLY HALF the number of TEETH that the CAM PULLEYS and AUXILARY do, as the cams and aux turn at half speed due to the engine being FOUR STROKE.
As to wether the pulley is the same on PINTO and COSSIE I could not say but would have thought so.
The pulleys for the cams + aux shaft will consequently be the same size as PITCH is fixed, has to be for the belt.
How far out is rotor arm ?, thye do suffer from ford itis, that is sloppy fits, but only wiggle a few degrees due to movement in SLOT of dizzy where arm sits, if so just pack out with paper or thin card, yet to meet a ford where I did not have to do this, and cured so many "sensor" running problems due to timing scatter.

cheers mate it was a pinto pulley and they are differant to cosseys and it was slipping
Paul.

 

All sorted now then ?
I did think afterwardss that they probably or most likely would have changed it due to different angle of timing belt having to go around another pulley and going down at different angle.
How much differnt are they teeth wise ?
