the engine's a 5.5 hp honda ohv knockoff from pepboys. cheng kang, or
it's an a go-kart. couldn't help it, it was damn near free. because it didn't
ah, but it didn't run because the dpo left it sitting so long the gas went...I
don't know what. I've never actually seen the inside of a carb look like that.
the jets were plugged solid and the gas in the tank was green. I mean, I've
seen lots of bad gas...but never that shade of green. so clean out the jets,
new gas, it fires! I needed a win after the pool. :-) come to think of it, the
gas was the same shade as the pool is far too often...
so it starts and runs...but it runs with an 'oscillation', I guess is how I'd
describe it. if you hold the throttle pedal down, it won't maintain a steady
rpm. up and down at a fairly frequent pattern. there's an actuating rod
attached to what I think is the throttle plate in the carb (there are two
butterfly plates in the carb--the choke and the plate to which this rod is
attached). this rod runs under the gas tank and is attached to the motor in
some fashion (can't seem and wouldn't understand it anyway, so didn't remove
the tank). this rod is moving back and forth at the same periodicity as the
engine rpm oscillation. clearly, that's what's causing it.
anybody know what that rod is, and what it's doing? some sort of constant
then there's a spring installed outside/over this same rod (the rod is running
through the center of the spring). one end of the spring attaches to the
'throttle plate' (?) cam right next to the rod. the other end was attached to
nothing when I got it, but judging by its length should attach under the tank
somewhere. anybody know what this spring is supposed to be doing? some sort of
I can't fit my fingers in to pull the spring, but I can hold that rod still,
and when I do, it runs fine.
so...I was hoping for a guess as to what that spring might be doing, which
might help when I take off the tank and try to figure out where to attach it.
or a description of what that rod is and what it's doing. or, if you know
exactly what to do, that'd be cool too. pep boys apparently sells a different
brand of these each week and there are no identifying markings on it to google
the maker. it just looks a lot like my honda mower engine turned upright.
thanks in advance.
