CB 360 Carb Rebuild

[motormayhem]

After going through a lot of trouble with my CB 360 carbs trying to get them to run right I wrote a rebuild guide for these carbs. Just wanted to throw it out there in case anyone else wants something to reference with a few more pictures than the manual.

I would not recommend using torch cleaners to clean the jets. While you may of done it right, the torch tip cleaners can remove brass material from the jets, making them both larger, and ruining the shape.

I use strands of copper wire, as it is as soft as the brass, and cannot remove brass or change the shape of the passage.

Also note, the slow jet replacements in the some kits have smaller emulsifier holes and a slightly thinner shape. If the original jet is not damaged otherwise, they OEM jets work better. I never use the carb kit replacement jets.

Also note that the replacement jets in the kits may be the wrong size. My 360 uses a 11o size main jet, the kits usually have a 100 size.

Otherwise it is a nice tutorial. You did a nice job there.

Thanks for the feedback,

Ya you do have to be a little careful with the torch cleaners but I have never had a problem by using a cleaner 1 or 2 sizes smaller than the hole so your not filing out the edges of the hole. I think I noted something about being cautious with the cleaners, but I'll suggest using some copper wire too.

The rebuild kits I used/linked to dont come with new slow jets so you have to re use the OEM ones but that's probably a good thing to note as well.

Let me know if anything else catches your eye I'm gonna try to get some more tech articles and info for the cb360 together when I can find some time.

Guide looks great. I'm about to start on my carbs and will use it.

Good guide, except as noted
Copper wire is softer than the brass jet so cannot enlarge any holes.
Stock pilot jets work best (unless you have equipment to modify the aftermarket kit jet to stock sizes - I do 8) )
I've found the actual jet is undersize even though stamped as a 35
I don't have any drills smaller than 0.30mm, some jets are smaller than that (little over 0.012" or twelve thousandths of inch for the non-machinists ;D )
