Title: How to lock out the 009 distributor? Post by: airstuff on July 21, 2008, 20:17:43 pm Hi people,
Can someone please explain,what needs to be done to the distributor in order to get it locked up(ignition curve)? Pics would help also.... Thanks. Title: Re: How to lock out the 009 distributor? Post by: airstuff on July 22, 2008, 20:26:35 pm come on guys,is it a secret? :D

Post by: gibber! on July 22, 2008, 21:03:00 pm Did I hear somewhere about threading a bolt through the case of the dizzy to prevent it from fully advancing... and therefore making it possible for you to arrest the advance where you want?
Or am I way off.... ??? Title: Re: How to lock out the 009 distributor? Post by: Diederick/DVK on July 22, 2008, 21:21:34 pm i thought it had something to do with welding weights into the dist...
Title: Re: How to lock out the 009 distributor? Post by: Mike Lawless on July 22, 2008, 21:25:46 pm There's a limit tab on the base plate that limits the amount the advance mechanism can move. You can bend that tab to the point that advance is locked out. Otherwise, perhaps spot weld the advance plate to the base plate.

Quote The next thing was to modify my 009 dizzy to limit the advance to 24 degrees as per again ourkids thread first as he says you have to have an understanding of how the mechanism works,this is a centrifugal advance distributor that relies on weights moving out as the distributor rotates untill max advance is met,the total advance is too much for a turbo so has to be limited first strip the dizzy down to its component parts and identify what does what,the pic below shows the weight (with the plastic pad) and the stop it hits as it moves out (http://i48.photobucket.com/albums/f215/kevdonlon01/DSC00029.jpg) the next thing to do is drill and tap the stop for a 3mm grub screw (http://i48.photobucket.com/albums/f215/kevdonlon01/DSC00030.jpg) reassemble the dizzy and pop out the cover on the side,this will allow you to rotate the rotor arm so you can see the new grubscrew inside and adjust it to limit your advance (http://i48.photobucket.com/albums/f215/kevdonlon01/DSC00031.jpg) using a protractor i marked a line 7 degrees clockwise of the original timing mark, i drew a line on the rotor arm and lined it through,then using a screwdriver i opened the weight towards the grubscrew untill the line on the rotor arm lined up with my mark 7 degrees away, i then adjusted the grubscrew onto the weight and this should now limit its advance (http://i48.photobucket.com/albums/f215/kevdonlon01/0092.jpg) and with the rotor arm removed for clarity (weights being held against the grub screw stop) (http://i48.photobucket.com/albums/f215/kevdonlon01/0094.jpg) When my engine is running i will set the timing at 24 degrees at 3000 revs and lock it off,according to what the timing is when it idles i may slightly adjust where the weights are limited to but always resetting to 24 degrees at 3000 revs (basically only the idle timing will change then) Disclaimer,i am no expert on this,i have tried to follow previously done work and include pics as i go along,dont moan at me if you follow this and your motor blows up,mine will have already gone and i'll have too much work on my hands putting it right to worry ;) Title: Re: How to lock out the 009 distributor?
