Hello all,
I'm new to the forum and currently in the process of rebuilding my 722A carbs for my 72 Cl350! I purchased the bike about a month ago and the PO said it fired when he sprayed carb cleaner in it, I confirmed this when I got home. But this also had gas in it while it sat since 2013, we all know how that goes. I cleaned the fuel tank out now which is just about spotless and rebuilt the petcock and installed a new fuel cap gasket. The tank is currently sitting on the shelf filled with gas leak free. Onto the carbs.
So I tore down the carbs completely and soaked them in Berryman's Chem dip for 24 hours two different times. I noticed the bowls and jetting area had a white almost calcium looking residue you could maybe call it?
*NOTE: In some pictures the carb is still wet from rinsing*
In the 3rd picture of the right carb bowl area you can really see what I'm talking about. I was told that simple green would remove it easily so I put them in for about 10 minutes in a simple green mixture in my ultrasonic cleaner but did not want to leave them to long in fear of discoloring the bodies, I also tried scrubbing it off with a toothbrush to no avail. What would your advice be? Run it the way it is or do you know a better trick?
Also, I noticed the choke butterfly screws on one of the carbs are loose. Is it at simple as tightening them back up? I had a quad that I loosened the throttle butterfly's and they told me to JB Weld the scews back in does the same thing apply here?
Thanks for any help everyone I do have a Clymer Manual that I have been working along with!
