Hey all, just bought my first snow blower a month ago, an early 70's Ariens 4hp 20", from my research I believe a 22000 series.
Model #922999 serial #006880. It's missing the handle and a couple parts that turn the auger on and off but other than that it's in pretty good shape.
It ran good until the main belt broke which I replaced and now I just can't seem to get it running right.
I cleaned the carb and the bottom screw is turned to between 1 and 1 1/2 and the mixture screw is about 1 1/2 turns as well. I think the governor is off though but I'm not sure what it is supposed to look like. I'm trying to post pictures but apparently I can't since I haven't posted yet.
Is the governor supposed to be straight up and down at either full throttle or throttle off? Thanks in advance for advice.
no location given for pricing, but you can bolt up a honda ohv clone ( 6.5 hp) with just a bit of work, on the cheap. add impeller kit......and you would have a little beast that runs quiet and starts easy. jmo
Hi
Welcome to the forum. If you haven' t disturbed the governor arm yet, don't. It is most likely not the issue anyway. There are some good videos on YouTube that explain how to set up your carburetor. The carb may need a rebuild kit installed or maybe just a good cleaning. MH
Thanks, I messed with the governor some, so it may be out of whack. I've tried tuning the carb and I cleaned it, but it was pretty clean to start with and did run good before the belt issue.
How many posts before I can post pictures?
Ok gotcha, yeah I need to finish updating my info. I'm in WA state. I really don't think this one needs much to get it right, I just don't have any experience with governors.
Good luck, I too would rather see it running, repowering is a good option if the engine is worn out but if it doesn't smoke or has lost a lot of power I try to leave them original if I keep 'em. Selling it may bring more money with a repower though.
Worked a little more on the Ariens last night and I'm close. I think the linkage from the governor to the throttle is on wrong and I need a new spark plug which I picked up today. What is a good compression range on these 4hp Tecumseh's? Mine was 150 on my gauge.
You'll have that baby running sweet in no time.....I just did over a similar Ariens with the five horse engine....hard to believe after almost fifty years, they still do the job....I wish they didn't have the two shaft Tecumsehs....just in case we want to repower with the Harbor Freight engine!
I think the issue is with the carb, I got it running again last night but it won't do anything but idle and adjusting the 2 screws on the carb doesn't really make any difference. I'm thinking float issue? I'm just going to pull the whole carb off tonight and go through it better and hopefully that will do the trick. If not I will just order a new carb for it.
Anyone know the correct aftermarket carb that will work? It's an HS40 55265B motor, and I found a replacement carb for $75 but there has to be one of the $15-$30 ones on amazon/ebay that will work right?
