Shocking carburetor damage.
« on: June 13, 2019, 11:42:05 am »
Doing my last carb overhaul before a late summer fuel injection retrofit. On disassembly I discovered #3 pilot jet had the head broken off. Found the threaded portion with the emulsion tube iaying in the box after I de racked the carburetors. Head was missing so that pilot jet was definitely sucking a lot of fuel. #4 Diaphragm spring was broken about 2/3 of the length. My last ride I was getting 20mpg. Bought a set of ZG1200 carburetors for the overflow tubes, the diaphragm springs, and various screws.

That’s crazy. Surprised it even ran that well.  My son has a 92 and we would like to rebuild carbs. Is it very hard?  Special tools or skills?  Did this before on single cylinder bikes. I have the vacum gage for balancing which we already did once. Thanks

Been a pain in the ...most of the screws were pre stripped for my convenience. Since the newest C10's are now 13 years old the carbs needed to be de racked and have new orings on all the connecting tubes. I had to buy an ultrasonic cleaner and an extra set of carbs for parts. You would need JIS screwdriver set. Dremel for grinding a slot in stripped screws. Now that they have been apart 4 weeks I have a nice jigsaw puzzle to put back together.  Honestly, although I know I can successfully complete this I wish I had sent them to Steve. Lol.

As for the "jigsaw puzzle"..............I have been a mechanic of several disciplines all my life, and I find the digital camera (or your smart phone) is the best invention yet when taking apart unfamiliar stuff.  I used to use a Polaroid (you young guys can "Google" that  ;D).  Now I photo the crap out of stuff I may have a problem remembering.  Plus then you can blow it up for finer detail if needed, or post pics to forums like this if you need further advice (or sympathy).

  Yeah. I took lots of pictures.

I used a 50/50 pinesol and water mixture in my ultrasonic cleaner.
Works well

  I used a few capfuls of Zep aluminum safe degreaser. The ultrasonic does the cleaning not the solution so 50/50 is overkill. Very happy with the results.

Do you guys have shops or are these ultrasonic cleaners cheap enough to make sense for the casual owner?

I bought one at Hatbor Freight for $79. If you Google "Harbor freight ultrasonic cleaner review" you will see how it compares to slightly pricier cleaners. There is enough room to clean one carburetor not fully submerged so you have to flip the body one time.

One of the best things of working in healthcare is free stuff.
Scored a ultrasonic cleaner years ago they were going to throw out.
Fits a whole rack in with a hour timer.
