Carb overhaul - what are these tubes?

Just started to follow the guide by Cammo and turned the carbs to drain the float bowls and perhaps I turned then too far as fuel came pissing out of these tubes

What are they?

No doubt the first of a few more novice questions, sorry in advance

Dont know but thats where fuel pisses out if you dont drain them before turning them upside down ;)

Much easier to use the drain screw on the float bowls than spill fuel everywhere

You're right! :grin: incompetence strikes again ffs! Still got the grease off my hands anyhow.

Float heights will be checked too

Just while I'm waiting on the postie with new needles etc I thought I'd see what the idle jet screws were set at, and they were all wound out by more than 3 turns compared to Cammo's recommended 2 and a quarter. Wonder what effect that would have.

dont get confuses with half turns!

most people assume one turn is 180degrees with the slot one rotation, when it is actually half a turn

I'm not getting confused with half turns, at least I'm pretty sureI'm not, a full turn is 360 degrees, so I actually found they were turned out by 1080 degrees, actually it was about 1125. This was waht it took to wind them fully in.

Cheers

I was right then, so it took 3 and 1//8 th turns or thereabouts to wind the pilot screws fully in.

Not sure how that would effect running, however I have new main jets and pilot jets on order from Rick O and will wind the pilot screws out the two and a quarter turns recommeneded in Cammo's guide.
