Son of a beeeeppppp!!!

After pulling and cleaning my carbs (4 F'en times 2day) due to a bad judgement call on my part, wanted to see if this older tank would look good on my bike. So I mounted it and ran it for a while and well the carbs started acting up so I figured that I got some gunk in them. No biggy, after doing the ear shave pulling the carbs is a breeze. Well I blew out the float bolws with some carb cleaner nothing really in there but did it anyways, blew out the jets there was some rust particals in the rear carb, blew out the coasting enrichers, the front carb had a bit of **** in it. Put her back together and she runs a ton better than she did before all that work after the 4th F'en time BUT she still acts like she if flooding out. It takes about 2 minutes of running to get to that point. So now I am to the point of taken my sledge hammer to the F'en carbs. So anyone out there that has any ideas on what I might have missed please speak up and save my carbs before I do smash the hell out of them.


Peace

(I feel your pain brother, my carbs are ridiculously problematic and touchy too )

Do the floats move freely and are they set right? If so, it sure seems like lingering debris is in there somewhere. Changing the tank(s) like you are, have you cleaned out the fuel lines in between as well? Any chance of a "nick" on the float needle?

That's why I've installed in line fuel filters in my bikes. It's a tight squeeze on the Vulcan, but there is room for two small filters. Keeps the crap from getting to the carbs and gunking things up. There are some things that Sea Foam just can't fix!

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

Thanks for the input folks, after a few Margaritas and a handfull of beers last night I do feel better today and will give it another whirl.

Sometimes walking away and coming back with a fresh and/or hungover perspective works wonders.

Good Luck, and post up the results!

I don`t want to hijack the thread, just ask fc how big the filters are you put in-line. What is the length of the body, excluding the attachment nipples on each end? Also what is the diameter? I picked up an auto filter with a clear plastic body, but it appears to be far too large to fit 2 of them on the Vulcan.
