If anybody can help I have a 190xt and need to know if a 200 injector pump will interchange. I found one that has been rebuilt for awhile but was never installed.

Yes it will work. Set pump timing at whatever it should be for a 200 and there are two settings ?? 18 degrees BTDC and 24 degrees BTDC....numbers on the pump will determine which setting.

then maybe leave it at stock specs should be 93-106 somewhere around there if the cable is still through the screws.
