MattYorke Posted March 13, 2009 Share Posted March 13, 2009 You sure? It advances & retards based on engine vacuum, which is more akin to throttle position than engine speed. The distributor usually also has sprung loaded weights in it that adjust the timing based on engine speed. It advances and retards the timing depending on the engine speed. The vacuum is taken from the inlet on the plenum chamber. There will be a small pipe that goes from the distributor to the top on the right hand side of the plenum chamber, you want to remove this. With the distributor cap off, you want to suck on the end of the pipe. The distributor should then rotate its internal base plate. Quote Link to comment Share on other sites More sharing options...
mr.t Posted March 25, 2009 Author Share Posted March 25, 2009 Progress Update... Removed all the plug leads and cleaned up with a silicon spray, check all the connections to the plugs and ran tidely. Removed Distributor cap, used light emery to clean up rotor arm copper including where the carbon centre pin touches and cleaned up all the pins for each lead. (tried to check advance but rotor arm wouldn't come off very easily ...any clues chaps??) Already a massive difference...clear difference on Petrol or Gas... Seems to be more power everywhere... Won't kick down logically... having to drop it manually to accelerate up a hill on the way home that foils the Disco box into slowing the car in Drive... So, Plugs and timing check next....

Hybrid_From_Hell Posted March 25, 2009 Share Posted March 25, 2009 DO NOT pull rotor up hard - the bob weights pop off the shaft 2 Options Option 1. Flat bladed screwdriver, remove dizzy cap, look at shaft just below where rotor arm finishes is a lip on the shaft place blade of screwdriver on lip, push down REALLY hard as you pull rotor arm up Sometimes the arm will have bonded with corrosion to the shaft, which is then Option 2. Take cloth place around cover and under rotor arm Take big molegrips, crunch onto the shaft shattering arm connection to shaft, clean away debris carefully Fit new arm plus smigin of copperease Nige Quote Link to comment Share on other sites More sharing options...
mr.t Posted March 26, 2009 Author Share Posted March 26, 2009 Cheers for this.. My internal human torque meter was telling me something was wrong with the effort exerted! Cheers for the warning Mark Quote Link to comment Share on other sites More sharing options...
