Little holes in the carbs

[natemoen]

On the intake side of my carbs there is 4 little holes three holes right by the butterfly and one a bit closer to the outside. How does one go about cleaning out those holes? Where do they connect to? TIA

I would use carb spray cleaner and then compressed air (if available). Maybe this diagram will help some....

Caution using compressed air with the older carbs!

I would make sure that the brass floats are OUT of the bowls before squirting in compressed air. I've heard of folks compressing/denting their floats by squirting/applying compressed air while the floats were still in the bowls! JAT!

Remove your pilot jets and squirt carb cleaner through the hole. If the passages are clear the carb cleaner will bubble up through those holes. If it doesn't, spray cleaner in there and let it sit for a while and then blow it out with compressed air. Repeat as necessary.

TC, would removing just the bowl suffice for this? Not necessarily the floats.

From my understanding, I would think removing just the bowls would be okay. However, with the bowls off, the floats are exposed, and depending on how you have them out on the tool bench, they could be subject to damage that way. The problem I saw was having a closed container..bowl..where excessive pressure could build up during the compressed air squirt, and that then compressed the brass floats. I don't think it's a problem with the later year carbs with the plastic floats.

Thanks! Thats what I figured they were but I was not getting anything through the holes so matter where I sprayed carb cleaner, finally got them clear thought!
