1965 G707 Minneapolis Moline tractor which has a roosamaster injection pump on it. I take this tractor to some vintage tractor pulls and do demo pulls only , because of the intake and exhaust system modifications. Tractor starts really good and will rev up to the rpm its been set at (2000 ) rpm. Injection pump and injectors where rebuilt about 10 hours ago but a couple years ago. Problem is it wont smoke at all any more. Used to put on a real show with smoke and of course some noise as well. Seems to have lost a bunch of power as well. Took the top off and cant see any thing wrong but Im not to familiar with the roosamaster pump. Any ideas. Perhaps dieseltech will read this post. Thanks for now.
