Anyone know what size main jets and slow jets I have in these carbs or how to find the sizes on my jets?  I think I'm going to replace all the jets.  I cleaned them with a steel guitar string from an idea I got on another forum only to read posts by several reliable sources that is a bad idea after I had already cleaned them.

The size of the main jets is stamped on them, but you might need a magnifying glass to read them. However I can tell you that cleaning them with a guitar string will NOT! hurt them! You need to stop going to those Ginsue/off shore forums, for advice! Also a very good tip, for your pilot jets is to drill them out to 0.45mm. This will richen up the pilot to help it start easier, and run cooler.

I'm glad to hear that since I am no expert on these things (yet lol).  Actually one of my sources was the Clymer manual.  I assume when you say pilot jet, you mean the slow jet?  I'm all for starting easier and running cooler.  I'll probably have a machine shop do that for me since I have no way to accurately drill that except with a hand drill which would probably make a mess of it.  Since I bent every one of the slow jets when I pulled them, I'll go ahead and get new ones so the drilled holes wont be funky.

I with Tools on the jets. Unless you went straight up caveman on it and saw actual pieces of brass being removed/filed off when you cleaned them ...then you're fine. Some people online like to scare other people in to thinking they messed up just to make them feel smart. Your fine dude. Now post more pics! lol ( i really like pics)

Wintergreen Oil Mix - The ratio of wintergreen oil to water is 1 oz oil to 1 qt water.  I've been soaking my carb boots for about a month now and will pull them out of it when I get this carb assembly back together which will probably be in a week or 2.  (yeah I know I'm taking forever to do this)  That happens when you have more projects than you do time, lol

Well I wanted to get some new slow jets (#35) to drill  out to .45mm since it gives you a cooler idle but I cannot find any new ones anywhere.  I'm becoming convinced that these jets must not be in production anymore so I'll see if I can buy a set on ebay.  I didn't want to drill the ones I pulled out because they are all slightly bent from pulling them out with pliers (Since then Tools informed me I could have tapped them and used a screw to pull them out (doh!)  O well, those things happen when youre still in carb school.  I may try to straighten mine and drill them if I get desperate enough. Ha!

Well, Tools says drill the slow jets out to .45mm and Lucky says drill them out to .42mm.  I guess the right thing to do is drill them out to .42mm and test it.  I can always drill it out more if I need to.
Here's a tutorial how to drill these out.

 Instead of drilling them out to .45mm like he says, drill them out to .42mm like Lucky says.  You can always drill more out if you need to.

Finally getting back to work on my carbs
Had to take some time off to build a log rack for the mountain of firewood I have.  Built this 32 footer, barely had room for wood I had stockpiled and getting more almost every day so I'm going to have to add another 15 feet onto this one.  But I'm going to take a break from this and get my bike running.
