B & S 3.7 HP engine on sprayer; RPM excessive

[cptmclark]

Hello, This is my first post, so pls let me know if I should do it differently. I have an engine on this sprayer that appears the same as on a mower. I had it overhauled last fall, and this is the first start since. RPM is way up there, seemingly much higher than ever before. Under load it reduces, but it's so high I'm afraid of throwing the rod or having some other damage. Not to mention, it goes through fuel in record time. I suspect there is a governor that's not working. Not having taken the air cleaner off to see how the springs are attached, I need first to know what it should look like. i don't really know how the regulator or governor works, and so need help with that first. Thanks, Mike

Under the pull cord housing the flywheel blows air on a flapper that works the governor linkage. Most of the time wd-40 on the flap shaft(bolt) and working the flap a little will correct it.

Thank you very much. That's the ticket.
