Roosamaster Injection Pump

Hey Guys,

Does anybody have experience on turning up a Roosa Master fuel injection pump? It is on a 1963 50 HP Allis Chalmers HD3 dozer. I had the pump rebuilt but still not blowing black smoke and turning out the power. The engine has been rebuilt as well. I think I need to turn the pump up but don't know how. :shrug:

If you have a picture of the pump it would be a big help, some of them have an allen headed screw on the back of the lid that you can back out for more fuel. if it dosent have that you may have to pull the top off and tighten a screw down on the inside of the pump.
