I'm sorry TT, after I uploaded those videos I went back and took the carbs back off and found that none of the idle jets were screwed in all the way. I was a little anxious to get it all back together after cleaning on everything for 2 hours that I simply forgot. I put it back together and it's running a lot better. Still rich though.
It makes sense about the float adjustment and it running rich. I'll take them back off tomorrow and readjust them on their sides.
I also found that the main jets don't "seat" as tightly as I would like, so to go a long with your question, they all have o rings in place, but if they weren't sitting in there good (meaning that they are loose) in stands to reason that more gas will be able to come around the jets and make it more rich as well.
So I will definitely address those two situations tomorrow morning and report back to you!!
Can you see light through the slow jet from end to end?
Yes
I'm uncertain about the emulsion tubes... Are the cross drilled holes clear?
Some of those pictures are fuzzy, but they are definitely clear. I made double sure with compressed air and a wire to poke through each orifice.
Also, the float to pivot brass carrier looks bent. It should be flat rather than curved. The height adjustment bend is performed on the tab portion only.
The floats were all a little lop sided when I got the bike. I straighten(Leveled) them out the best I could so they would have the same movement through travel. To help I have been measured (although incorrectly) both sides of the float to make sure that 22mm mark was the same on both sides.
Are you using new orings on the main jet?
Are you using ANY orings on the main jet?
Yes they do have o rings, but they are pretty loose in the bore and will require replacing. I noticed that today. From me taking them off and on so many times I am sure that they have worn out.
You also need to "prove" the air jet passages. Since you have pressurized carb cleaner place the nozzle/tube into the air jet orifice and "prove" the fluid reaches:
A: the slow jet emulsion tube chamber, from the slow air jet.
B: the main jet emulsion tube chamber, from the main air jet.
I did this today and actually the pressurized carb cleaner came out that jet from where the choke valves are and squirted me directly in the eye. It definitely had great pressure, cause it shot up about 2 feet.. Washed my eye out immediately and dawned a pair of safety glasses for the remainder of my carb journey.
I will source those o rings tomorrow as well as adjusting the float height correctly. While its all apart I'll go through the jet orifices once again and make doubly sure all air/gas ways are clear. Put it back together. Fire it up and sync the carbs after a proper warm up and report my findings.
Woohoo. I love progress!
