Idle too high...can't adjust carb>

[Poboy kartman]

That tab is resting against that spring bound screw in the pic, is it not? Would it not stand to reason that that screw is the idle adjustment?

The guy I ride around with sports one of these engines. I'll try to get ahold of him soon to do some investigating.

Pay attention- The pictures of the carb with an idle screw are mine.HIS CARB DOES NOT HAVE AN IDLE SCREW! !!!! Read my last post.

To the OP- That doesn't make sense. The butterfly should close completely and kill the motor.There is nothing inside the carb to keep that from happening. It has to be external. Instead of getting frustrated you should communicate more. If you know everything-why are you here?

No one is going to tell you how to "rig" your clutch because that is not the problem nor the solution. If you did what I said- then tell me what you mean by "as closed as it can go" because that is just not correct.

Yeah, I kinda figured that out 4 1/2 hours ago; but thanks for the late heads up! Better safe than sorry I guess...

There's clearly somthing stopping it

It looks to be the little metal tab

If not
Then the throttle cable is holding it

I appreciate the info from you guys but you are going overboard with this....trying to tell me that there is a "idle adjustment screw." The tab is resting on the body of the carb....that's what stops it. THERE IS NOT A IDLE ADJUSTMENT SCREW ON THIS CARB!!!!!! I bent the tab a little but it didn't lower the idle because the butterfly plate can't close anymore than it is.
I saw another 6hp Tecumseh today at a lawn mower junk yard and the carb was completely different than mine....so yes.....my carb is not original equipment.

The thing about those Tecumseh engines is that there are a whole bunch of models that are built for different applications. That's why I asked for the model number. The basic block is going to be an 0HH60 but an 0HH60 xxxx is likely to be very different than an 0HH60 yyyyyy.At first glance, they will look the same. As I said in my earlier post the 0HH50's have very different carb/linkage set-ups. So first off- unless they were the exact same model number- what you saw means nothing. Secondly- even if they were the exact same model number, you are making an assumption that because yours doesn't match-you do not have an original carb. How do you know that that motor hasn't had a carb change? If it was perfect, why is it in the scrap yard?

The other part of your assumption is that because this motor/carb isn't operating properly- it has to be because it has the wrong parts. I could find the answer but I am not going to waste my time if you aren't going to listen and approach this problem with an open mind and help us to help you.

I feel it's getting a little heated in here; so please allow me the short derailment of this thread to provide a little comic relief in the form of a demotivational poster.

Not sure if this website I found has been posted but here it is

I hope it helps

Ok, here it is: That particular carb is controlled by the governor. If you remove the governor, there is no direct link to the throttle butterfly.

From the factory, (working backwards) the throttle butterfly linkage is connected via a solid rod to the governor arm which is then connected via a spring to a throttle mechanism; the idle screw is on the throttle mechanism...

Sorry about the blurry pics, I hope you can make sense of them...

There ya go- but what bothers me is the claim that the butterfly is closing as much as it can. I just hope he doesn't have any problems with his brake rods.
