I'm finally getting around to working on my bike, it's a 72 cb500 that was my dads, i remember when he bought it in the early 80's. unfortunately it sat with gas in the tank since the late 80's, so things were pretty icky. the tank has since been refurbished, and i picked up new fuel line. i pulled the carbs off as a unit, i haven't separated because i'm terrified of the thought of resynching them. i popped the float bowls off, and it's not pretty, not pretty at all. everything is gooey and covered with crud. to be honest, i'm rather intimidated by them, especially seeing as there are 4 of them. i've rebuilt volkswagen and vespa carbs before, but there's only 1 to deal with. i'm afraid i might be in over my head, and i'd be better off taking them to a shop to have them rebuilt. are they really that scary, am i just being a wuss? how much does a shop usually charge for carb rebuilds?

here's a recent picture of it:

If they're the constant velocity type, you don't have to worry too much about getting them synched,( I think). I had a pair of Keihins that were siezed up from old fuel. Cleaned 'em in an ultrasound tank, put 'em back together and installed 'em, didn't have to do much but adjust the idle speed. Even if they're not the constant speed type, the carbs aren't that complicated. Figure the first one out, the rest are gonna be easy...

That bike looks like it's in really good shape. I feel bad 'cause I kinda scolded you on another forum (didn't mean it to sound that way, but you did ask if you were being a wuss - plus several pints). those carbs are easy - lots of carb cleaner; not many moving parts. You'll do fine.
By the way, you have a cool looking garage; Cool Vespas, too.

no worries judeyramone, i appreciate the honesty. i was himming and hawwing over rebuilding the vespa engine on my own and once i got into it i realised it was just like all the vw's i've built over the years.

the bike is in all original condition, it's been garage kept it's whole life. only problem spot is on the tank behind the emblem, something dripped on it from a shelf above it and ate the paint. it's mainly the black area so it shouldn't be too hard to touch up.

the carbs are keihin 627B i believe.

1972 Honda CB 500
1974 Vespa 177 Super
1963 Lambretta Li 150

Those carbs are a cinch. Just do one at a time so you will have a reference. Should be smooth sailing.
