Ariens 924050 ST824 with Tecumseh HM80 gov linkage

hey gang, Bought this a couple weeks ago and it looks like someone has been in it before. I don't believe the throttle/ gov linkage is all there.


I did get this running. the intake valve retainer was broke in half. but I only found the one half. guessing someone pulled it out. I think it would be too large to fall into the sump.


so $35 for thrower and $2.14 for the retainer and she runs. all gears work as well as auger and diff lock. cleaned up well.


is there a thread on here with proper linkage installation like pictured?

oh yeah. note to self. watch how deep the threads are on your compression gauge. mine made contact with the valve. glad I used the pull start.
also, here is a pic of the broken keeper I found.

Does it have a small torx screw on the throttle lever, with a spring under it? I can't see if it does on any of you pictures. On new Tecumseh's they do, and its the high speed adjustment.

you should have 2 wire rods connected to the gov arm. pics of throttle lever and throttle linkage would help.
i just installed a carb on my 10hp tec, should be similar to yours, vid will show the linkages(2 rods) , 1 from throttle lever to gov arm and 2nd from gov arm to throttle plate. installing a digital tach will confirm if rpm is too high, should be max ~3600rpm



digital tach install

Hello LONG, that spring you have in the first picture is for the engine mounted throttle control lever, as seen in the attached video.

Experience is something you don't get until just after you need it.
