Adjustable carburetor in new 1999 tecumseh 9hp

Noob question.

My Yard man 927 has a dirty non adjustable carb, varnish, bowl edge under ring is pitted, ring is hard, runs a bit ruff, but I want to change it.

I want to know if I can install a brand new adjustable carb without any hassle ?? Will it run exactly the same or even better ??

I'm sure it's an easy question for experienced guys, that's why I'm asking.

Also why did they start installing non adjustable carb, just saving money ??

Thanks

Yes you can BUT you need to adjust it lol. The reason adjustable carbs went away way the emissions had to meet certain levels and that meant run lean and the gooberment did not want us making them run richer so they passed laws that they canít sell adjustable carbs on the engines but fortunately you can get them aftermarket.

Sno-Tek Modded, 15"X-Track tires (Now has same X-Track tires but 13"x4" for better fit), 254cc engine LED light and hand warmers.
Snapper 6/22 sold but not forgotten. Was my first.
Ariens ST1027LE workhorse and going strong.
New 2017 Ariens Deluxe completely rebuilt after losing a fight with a forklift.

Small adjustment I'm used to it, no problem. Start 1 1/2 turn on both then adjust idle and fast for good steady rhythm.

Thanks, will buy with adjustment in a kit if available, other separably.

I've replaced several fixed jet carbs with aftermarket ones.

Frankly, sounds like it would come right back with a cleaning and an O ring . . .

yes it would, buying stuff for cleaning and replacing rings, needle bowl gasket the whole thing in my spare time, but for less then $20 just want to install a brand new one, for this winter and will play with it afterwards.

With the snow we have around this time at 6 to 12 inches per shot, don't want to shovel.

Still replacing belts, bearings, did a lot of work on it, and not finished. will do the rest this summer

Not up to speed on yours but a lot of non adjustable stuff had caps or plugs and remove those and .......


Not sure new carbs available for blower that era. Quick clean up and see for now might be a better option.

Do you mean trasnforming a non adjustable carb into an adjustable carb with replacing needle on side and bottom jet ??

The last Tec kit I bought (last year) had everything, and was about $13.00 from a dealer, and about 30 minutes to do the clean . . . and you have not indicated that you need the full kit, so I still don't get it . . . sorry! Seems like you would be far more likely to spend more time fighting Chinese junk parts than that . . .
