Its the new hd camera that makes it look like that. The other side where the paint is looks like new. Heck the auger has most of the original paint, I don't think this machine has had much use. It was on display in a huge Ariens dealer's showroom.
What I need now is to find the number of bowl carb that was used on a similar engine. What's confusing to me how to put a bowl carb on this machine unless its desgined for the same hp. Case in point, I turned my 75 hp outboard into a 90 hp by changing the carbs. The diffenece in the 3 carbs were air restrictors in the throats and the main jets were smaller on the 75.
If you go onto an Ariens forum they talk about this engine all the time as 2.7 hp (which is what the sticker says on my engine) but on tecumseh sites and the manual it call this a 3.5 hp. I have never gotten an answer for why is says 2.7 hp vs 3.5.
HP can change based on how fast the engine runs, among other things - That is part of the reason behind the lawsuit long ago that caused manufacturers to start rating engines by Gross Torque - Because due to CPSC requirements (blade tip speed) engines had to be "throttled back" and thus produced less than the sticker HP.
Just get a carb for a 3.5 or 4 HP Tecumseh H35 or H40 (or HS40, or HS35 or HH35, etc) from the picture, that's a pretty common throttle lever - your main difference in a new float carb likely will be the choke lever configuration (but if you get one with manual choke, the lever can be bent to the needed shape if you have to)
This one for example -
https://www.amazon.com/dp/B094MV76YT/re ... s9dHJ1ZQ== should be a drop-in fit , you may need to bend or re-configure the choke lever in some way to fit the snowblower, but the fuel fitting is straight in like your diaphragm carb, and the throttle lever is about the same configuration, so it should fit right in and not need to modify the throttle link at all - just take a couple measurements on your old carb and/or your intake tube to be sure it'll bolt up, and that float carb (which is fully adjustable) should do the trick, and at 16 bucks a pop, I'd get two , if the first one works, you got a spare.
