Sea Foam costs about half that, and a bottle will treat that blower
carb 4 or 5 times, at least. And it's a whole lot less work.


Having tried a variety of alleged "carb and fuel injector cleaners"
and
haven taken apart carbs to clean them, I'm very skeptical that any
carb cleaner that you just mix in with gas is gonna cure a fouled carb
in an engine. Upon taking them apart you find varnish and gunk that
is difficult enough to remove with carb cleaner sprayed on full
strength
and rubbed with a brush. Plus, especially with today's gas, and
cheaper
carb parts, you often find needle valves that are rusted, etc.

With the carb rebuild kit you get the new needle valves, gaskets,
o-rings, etc. And doing the work is maybe an hour and a half.


Takes me at least 4hrs of work and an overnight soak to remove, tear
down, soak, re-assemble- re-attach-- but I'll better your 1 1/2 hours
anyway.g Once I've invested that time, effort & money- I don't
know what the outcome will be. did a tiny ball go missing? Did a
seal slip? Did I break a piece & now have to buy a new carb? Did a
Welch plug hide something important-- or did I remove it and not get
the new one in just so? [all things I have done in the past 40yrs of
carb-adventures]

I add a few tablespoons of K100G to a full tank - start the machine
and go do something else. This stuff goes wherever gas can go, and
it cleans all the crap without disturbing seals, seats, or plugs. I
rarely have to repeat it, but if I can get an engine to run for 5
minutes- it is well worth the effort to try.

My neighbor is a small engine repair guy. He's been doing it for 40
years or so. He turned me on to the stuff.


Another similar product is BG 100K - we used to say it was strong
enough to eat the backside out of a dead skunk from 100 yards.

This fall my snowblower didn't like last winter's gas. It was
running rough and searching for a speed. A tankful later, it was
running pretty good. I repeated the treatment- and now it runs as
good as it did in 1975.
