Failed CO emissions - all controls removed - where to start?

I put engine lube on the sides of my wooden one. Slides in and out a lot easier. The blue plastic one is one use junk but good for copying to wood. Scared me to death when the cheap pull out cord broke.

When you click on it it will download to your computer or phone.  Check your Downloads area.  Or, you might not have a pdf file viewer on your system.

I created an image from it.

FYI...I can't open it or save it. Not sure what's going on.

Mine downloads fine.  Click the DOWNLOAD as seen in my screen grab.

OK, it downloaded in Chrome. Firefox blocked it. Thanks for the nudge.

The only dimension noted is the length. It would help to have a dimension for the top width, the distance to where the block narrows, and the width after it narrows.

Not complaining, just trying to make sure our online friends have the info they need.

The curved side goes with the chain's curve.  Straight side on the straight side of the chain.

You want to drive it down until it hits the lower chain sprocket, red arrow.  You'll feel it "click" into place when it pushes the tensioner in, yellow circle.

I can do that!  Quick beer first, this makes my head hurt just thinking about this little job.

It's 7/8" at the bottom and 2 1/2" at the top.

Well Mr T Wood I hope when you print it out the measurements will be true and you can lay it down on a piece of wood, draw it out and then cut it out.

Let me know if I can be of anymore help. Cliff

I just remembered my first time doing this, nervously I will add. 

I used a long screwdriver turned upside down.  The handle fit perfect and held the tensioner back then my nightmare began.  I couldn't get the damn screwdriver out!  Finally got a good hold of the flat blade with some vise grips and pulled like a mother.  Then I did my Happy Dance.

Thanks very much for helping with more measurements.

And I hear you - if you managed to do that with a screwdriver, I bow to you, and to both your mechanical prowess and considerable good luck!!  ?

Well thank you!  I am lucky, scares me sometimes lucky. Frugal too, scares OTHERS sometimes frugal.

I made the one from the down load plans. That being said I would hesitate to go too deep into this. Back to orig problem failed HC, so I assume rich setting. easiest thing to try 1st is to confirm AT THE ECU the resistance values vs. Temps on the temp sensor. A little bit too much resistance there and you end up with a rich run. Next Start switch enrichment, again it should not be there AT THE ECU when key is not on "Start". Lastly AFM air temp sensor, again AT THE ECU. Since it has the stock ECU might as well make sure those parts are sending it good info. I just seems like its going to be hard to know what is working without a way to monitor the exhaust gases with any changes made.
