We are back in the shop today for a quick static governor adjustment video.
Now this is a Honda GX-160 horizontal shaft engine this one
actually, looks like it's been taken out and
somebody tried to adapt it to be a go kart engine.
so i'm not sure the governor system is completely functional on the inside
I can see the spring here is modified but the parts are exposed i'll go
through and do the static adjustment um just the same to show you what that
would be if you read the manual whether that
manual is from briggs stratton or honda or whoever it will say to operate the
throttle linkage from closed throttle to wide open
throttle
closed throttle right here the throttle is
closed against the idle stop or idle speed screw
wide open throttle there it's closed against the
wide open throttle stop on the carburetor
so this is closed throttle that's wide open throttle
and you can see that the governor's spring although it's been modified
it is pulling the throttle mechanism to wide open throttle
it's the job of the mechanics inside the mechanical governor system
the speed sensing element flyweights etc to pull the throttle closed to prevent
the engine from over speeding the static adjustment is getting these
parts on the inside of the engine up next together
where they can mechanically work together in unison
to sense the speed and close the throttle and keep it from over speeding
when the engine speed drops of course the spring would then allow
the throttle to be opened against the the
loss in pressure from the flyweights on the inside of the engine so how do we do
the stack adjustment we look at which way the throttle will
work so that's closed throttle wide open throttle
closed throttle wide open if i look over here
at the shaft where it goes inside the engine right
the other governor lever and the governor crank or
governor shop going inside the engine we can see that it moves
oh maybe an eighth of a turn and it's moving
in a clockwise direction here's a look inside that honda gx160
engine you can see there's the flyweight mechanism
and then this is the governor crank that goes up against the governor cup now
again this governor was tampered with so the flyweights are not working
correctly but you can see with the static adjustment what you're trying to
do is get this flat of the governor crank
up against that pin so that the speed sensing elements are next to each other
so the static adjustment then would be to loosen the pinch bolt
so i got 10 millimeter on here i'm going to loosen her up
would be to loosen the pinch bolt
hold the throttle at wide open throttle
and i'm going to use some locking needle nose style
locking pliers commonly called vice grip pliers
to lock onto the shaft i'm holding the throttle
all the way at wide open throttle which the spring actually helps me do that
already and then i rotate this shaft
in its normal directional rotation which it looks like it was already set
because i couldn't turn it anymore so you can see i do have a little bit of an
adjustment here so if i'm holding this a wide open throttle
and again the spring is doing that for me but i'm making sure it's that wide
open throttle i know it's supposed to rotate clockwise
so i'm going to rotate this guy all the way clockwise until it gets against its
stop and now
i'm going to tighten the pinch bolt and that is the static adjustment set that's
the first adjustment you would do on setting
up a governor system from there if you had a governed
idol you would adjust that and then after
that you would take this thing up to no load speed
obviously with this one i'm going to have to completely fix this
governor spring arrangement if i'm going to put it back to use as an outdoor
power equipment engine and really get the governor
operating correctly.
That's it for now hope you can get those
governors set up and we'll see you in a future video segment..
