Hello, I am wondering if any one has a definitive carb cleaning guide for a 1974 DT175? I am pulling bits and pieces of understanding from the many posts regarding carb issues on the forums here, but want to tear into my bike with a full walk through guide as backup (never had the heart out of the machine and in my hand before).
Does anyone have a guide or can link me to one that that have used? Any and all advice and cautionary tales welcome!
I have recently rebuilt a 74 174 carb. I used my 8 or 9 previous tear downs and rebuilds as a guide. I can answer, maybe even with pictures, any misgivings you have. I suggest you just take a lot of digital pictures in the beginning, as you are tearing down, and then when you are stuck, refer to your pictures. Yamaha and Partzilla as well as some of the other sites and manuals have good exploded diagrams as well, and I would suggest you order as many parts as you can in advance. Then start the job. My first one was spread out over two weeks, as I ordered parts after I opened the chest cavity, and the order was delayed two weeks awaiting some lousy little part. I forgot where things went in the meantime. Get the parts, and when you are ready, get back in this thread, and I'll be watching your work. You'll be fine.
Did I mention I spent 28 years as a teacher?

Due to the forums here and much YouTube research, it was a quick teardown and remount. Carb was pretty clean, blew out needles and ports; no significant wear. Played with idle set screw after remount and got to where I wanted to go after running in and backing out 3 turns. Thank you all!
Good news. Usually a snap. Were the jets in it Mikuni jets? Small overlapping boxes logo? And if it had one, how was the condition of the small black rubber O-ring on the jet setter, the needle jet, where it goes into the float bowl?
