GL1100 carb cleaning?

Post by OldguyGlen » Thu Jan 10, 2019 4:15 pm



Got 'em pretty well ready for re-assembly, but can't get acceleration pump discharge nozzles clean.
There is a tiny hole on the inboard side of these tiny brass plugs (by the choke butterfly). Do these nozzles come out? I don't want to end up breaking them, or not being able to reinsert them properly.
2 carbs came clean, but they only had one passage to them and I could get some pressure on the carb cleaner spray. The other two have multiple ports leading to the discharge nozzle (#3 & # 4) and I can't seem to plug all the extra holes to get pressure into the nozzle itself. Comments?

Some of these threads about carbs say to use a guitar string to clean em.

Thanks for the reply. I have multiple small wires (0.010" to 0.025") that I used for other jets. Don't know what size this particular port hole is. But the hole is on the inboard side. Its hard to find that tiny hole working blind, with a "U" shaped bend in my wire probe. It way too long a reach to go at it from the far end of the carb. I was hoping someone had an easy fix, like pulling the nozzle out, and just pressing it back in without damage.

They seem to be pressed in pretty tight, I wouldn't try to remove them. I have done the bent wire thing, not easy but it can be done.

I cleared mine by using an airgun I found in the shop at work. Somebody had adapted a section of metal automotive brake line to the end. I went in from the carb outlet side and blew the obstruction back through the carbs. It took a few tries but I got them all squirting really well. I don't know if any of them plugged back up but it's been running fine for over 4 years now....

I finally got them working. Much spraying with carb cleaner, air, and poking with a fine wire . Used a 0.011" wire, when the 0.014" wire proved too big. Takes some patience. Thanks for the advise all.

glad to see you got it done.
for anybody reading this, don't try removing them. i was curious to know if they could be removed and had a spare carb that i was willing to sacrifice.
i managed to get it moving a bit then it stopped. i was hitting it harder than any reasonable mechanic would want to hit such a part and it still wouldn't come out. even if i had succeeded, getting it back in and lined up properly would likely have been impossible.
i did learn which passage feeds it though ... somehow i managed to miss that when i was cleaning my own carb set.
