560 Roosa Master Pump timing

Porky 560 · Jul 16, 2009

I have the window to time the pump but don't know how to go about it. Where to start and what is the best setting for pulling. Thanks

Have a 560D I Wanted to do the same thing you did but I did not have a
timing window and did not know what the crap i was doing

but i did take the top cover off and move that spring out of the way and
then took a allan wrench and turned the screw 3/4 clockwise and got 2200 Rpms and alot of smoke. then put it back together

got second place in 7500 first time I think it was luck.

But later I had a pump doctor set it up run 2400 rpm
and now it has around 80hp. not as much smoke more power.
