Before you turn the fuel delivery screw I'd set the low idle and the governor bumper spring. Unhook the throttle cable at the pump then back out the lower bumper spring set screw until the engine no longer slows down on rpm then adjust the top low idle screw in until the engine idles at 810 rpm with the A/C on. Then turn the bumper screw in until the engine idles at 900. I'll jack the throttle to check the adjustment after I'm done to fine tune it and make sure that it stays. That adjustment is critical for the governor to react and work properly

That is exactly what I did yesterday off camera. I set it to 825 then used bump screw to take it to 875 per the service manual. Thanks for the comment

@@rgfarmsrepair503 I like to bump them the full 90 RPM and have it idle at 900. Keeps the PTO chatter away at low idle and makes it react quicker. Did it wake it up?

@mattvandevelde3839 It was pouring rain outside so I haven't been able to try it out. I bet that is going to fix it because ur right it seemed like governor wasn't holding rpm under load and it was getting worse. It idled low after overhaul but must have settled in and started idling lower. I will readjust it today as you recommended 👌 thanks

How much horsepower is that magnum supposed to have. Because my 8770 plays with my 16 row on the hills. Just need to add some weight to the front.

250 I think it just needed pump adjustment. The bulk fill does make it pull harder than a box planter I can put 100 units of seed in it at a time and more hyd horse power to run pto pump and blower motor off remote
