Definitely clean in my book
The little 'pipe' is just a locating dowel peg
Pretty sure the last time I priced one of those style genuine carby it gave me a nervous eye twitch ($100+)
Part number is 492611 - seems to be some knock off carbys available
Please do check the carby bowl for porosity (small rust holes). Have seen one that would run fine at idle (eventually after starting with fuel down carby throat) but die after 30 sec full throttle as it bowl was leaky and couldn't sustain fuel use.
Do you have access to a ultrasonic cleaner
