Tecumseh Carb sub? Toro 824 Power Shift

A question for the resident experts here: Any concerns with swapping the standard carb (Tecumseh 632334A) currently on my 8 horse Toro with a newer one from an 11 horse Snowking? My father-in-law let me take it from his 2009 Husky snowblower that threw a rod (long story). They look identical except for the fixed/non-adjustable power jet on the bowl and no idle mixture screw. It's very clean and still looks shiny, and the bowl (inside) is spotless as he was always fussy about running the fuel out of it in the spring and used stabilizer religiously as well.

Just thinking of it being a possible spare as the original carb has already been re-built once and it's getting tired again.

Thanks in advance

I'd go for it. If anything it may run better. Running a little more on the rich side.

You might have an issue with the engine bogging when the throttle opens suddenly.

The carb from the larger engine may have a larger venturi to accommodate the greater airflow of the bigger engine. On a smaller engine, the lesser airflow may not be enough to draw fuel through the main jet (or draw enough fuel) and the engine could lean out.

My advice would be to compare the size of the venturi (the narrower part of the air passage through the carb) on each. If they're the same, swap them. If the one on the 11HP carb is larger, you could have trouble using it on the smaller engine.

Be alert! America needs more lerts.

Thanks guys. That's good to know. If anything, I assumed the fixed-jet carb would run leaner since I always figured Tecumseh went that route a few years ago to reduce emissions. It will be an easy swap. I took the intake with the carb from the 11, and it's the same part as on my 8 hp. I'll hold off swapping it until after the current season is over. (If that ever comes! Boston ticked over 104" of snow last night: Now just 3.6" away from the all-time record of 107.6".)

Good point and will-do. Thank you!
