I have an old Ariens snow thrower 1977 Mod. 924032 Ser# Engine 7hp tec H70-130210D My issue is when it starts RPMs are low (about 2600 rpms) as it warms up RPMS will increase and stay steady at 3500 RPMS, with no load engine runs smooth. When I put the drive gear with auger running rpms drop to about 2800 rpms. last season with snow it would bog down and not throw snow. So what I have done is replaced the governor with new, changed the points and condenser checked valves, all seams good. when the engine is running (no load) I can push on the governor and get a fair amount of resistance. I am at a lost on what to look at next.
I feel when we get snow that I will have the same issue as last year. Is there a way to test engine load that the governor is working correctly.
Any help is welcome.
