Not on 99% of small engine garbs, you have an idle screw only and the

Pretty sure virtually ALL of mine do--I will have a look later.


If it is an older engine it will have an idle speed adjustment, idle
mixture screw and high speed mixture screw. Newer small engines often
have none of that.


Just as I thought...

I just finished checking a total of 3 chain saws, a of couple weed whackers,
a roto tiller and two generators that I have here--and each and every one of
them had a needle for idle and another needle for high speed and yet another
screw for adjusting for idle throttle position and so I must conclude that
anyone claiming that 99% of small engine carbs are lack an idle mix
adjustment most asssuredly is completely full of horse ****.

Oh, and FWIW, Karl's tiller in all likelyhood has a zenith 61 on it which
( not surprisingly ) also has an idle mix adjustment....

But hey if somebody wants to ****ing piddle around spending money and time
doing needless repairs on outdoor power equipment then more power to em I
guess.

--Just keep in mind the reality here is that reason Karl asked about it in
the first place was because he wanted to try and make sure that he wasn't
perhaps wasting time and money doing needless repairs....
