One of my first days as an apprentice cabinet maker, (yes, I am a lowly serf ) one of the masters came to me and said, "You need to learn how to steal". I was shocked to hear this and it showed on my face. Then Paul finished his sentence,.... "with your eyes!!" He said that Alfred who I was assigned to help was a master and I should watch carefully and steal with my eyes because eventually, I would be expected to do everything that he does without any help from anyone or I would be out the door.... Well, I did learn incredible stuff from Alfred, but Paul's comment crosses all lines of mastery, so I try to pay attention and steal from the many knowledgeable people I meet in real life and who's ideas I read here...
My latest bit of theft is from Concours, who keeps saying not to poke the amal pressed in jet with a guitar string, but buy the mini drill set and epoxy the correct sized tiny drill bit into a spray can straw so you can "hand" drill out the pilot jet in order to keep them clear and ensure the idle air circuit works flawlessly... (idle jet clogging or partial clogging being a hard to fix but common problem) So here's the Dr Suess pictorial
You buy these, but the stylus can not reach far enough down the idle air screw passage to drill the jet. You find the proper size bit for the jet you have and move to the next stage:
You find an unused can of something with a clean straw attached to the side of the can, mix up some JB weld or similar and assemble your magic wand thusly.
Never being satisfied with a single magic wand, I made a double so I can drill it out in stages for the least chance of breaking the bit or the wand while clearing the jet. The line you see where the tape is placed on the wand indicates the full depth of the port including passing through the jet. You also check the wand length once you're done drilling the jet with the paper so you know that the wand did not break off in the jet... Super important to know that what you stuck in the jet, comes completely back out of the jet... Here's my double wand below.
I let both wand assemblies cure over night to make sure they are solidly held. Like most of you, I have lots of extra parts. Some years ago I wanted to inspect the mixing chamber on a carb so I removed the welch plug which you can see in the photo below. I also pulled out the pressed in jet.... (I'm way too curious for my own good) But you can see that I placed the tape where I know the wand and bit are fully inserted when the tape is flush with the opening. This is so you can gauge your resistance when you insert your wand. (which if it fixes your crappy idle does indeed make it a magic wand) You want to observe the depth by looking at the tape position and gently twirl the wand with little push and pulls until it's feels smooth. You could put a tiny bit of oil or carb cleaner too, but I would go very light on the oil if you use that. Here's the way I determined where to put the tape.
Don't forget to poke both the mixing chamber holes from the inside of the carb so the fuel can flow out of the mixing chamber holes at idle. Thanks Concours for always adding the comment about making a magic wand out of a mini drill to clear the idle jet. It works much better than a guitar string...
