ok so i've read three hundred ways to adjust the starwheel seems like the top to the engine. now is that the screwdriver or the starwheel nobody really explained it too well. well my starwheel was at the front (radiator side) of the afc housing. i adjusted it back (firewall side) and the smoke never changed and it also seems to have more power like this. i also slid the stock plate forward and afc forward. reading the starwheel adjustment directions it seems to be the wrong way. not only did i get better bottom end i got better top end. does this seem right. i slid the plate and afc first and then adjusted wheel. i would rather more lower end than now but it seems like i got more on both ends, and i don't know why it didn't change like it was supposed to?

 

What did you do your afc and star wheel are in the back of the injection pump what are you trying to achieve by turning the star wheel towards the motor and brining it foward you should be pumpin in more fuel at a lower boost

 

i slid the afc and fuel plate full forward. i was trying to adjust the starwheel to get more upper end power and i got both. i wanted more lower end but it seems like it gets more when it is turned away from the motor and the wheel physically goes to the firewall? i'm wondering if this seems right. i was thinking since i moved the plate it maybe changed the torque curve. i'm gonna do a 3k so it'll run up more. i seem to have more power when the od and torque converder are locked in. sorta doggy when i try to build up speed until around 45 then lotsa power. i don't get any black smoke when i take off and i thouht that was wierd, unless in need a boost elbow since i have more fuel i might need more boost.

 

The star-wheel allows for fine-tuning of fueling based upon boost levels.

When the wheel is more towards the radiator it relaxes the spring pressure on the AFC foot. This foot holds the governor arm back (less fuel) when the boost is low. As the boost comes up, the foot moves forward (towards the radiator) to allow more fueling. At the higher boost levels this fuel can then be burned more efficiently (less smoke).

By sliding the AFC forward you make a more coarse adjustment to the AFC foot allowing more fuel earlier. This is why you noticed more power (both low and high end) when you slide the AFC forward and moved the plate forward. With a very 'tight' star-wheel (rotated back towards the firewall) there is more spring pressure on the AFC foot and it requires higher boost levels to move it out of the way. this results in less smoke and a little less power on take offs. Hopefully this helps.

 

thanks thats the best explanation i've ever read.

 

I didn't really notice anything from moving the starwheel around..
