Spring startup, and leaky carbs....

Post by leakyroof58 »



So last year was my first GW. A bucket-list item for me (I'm 61).
Ran super, no missing, hesitation, etc. Thought I got a great deal.

Put it up for the winter using all the tricks seen on this site -
full carbs, 2X Marine Stor-X, Seafoam, etc....Then this spring I
turned on the gas shutoff....wasn't long before I noticed leaking
gas, from at least one carb on each side. It SEEMS to be getting
better with time, as if the gaskets are now swelling again, but
why would they dry out in the first place, since I took all the
precautions?. As of today, the leaks slowed down enough that
I took it for a short ride around town. I have always been impressed
with the throttle response on this bike - crisp, and no stumbles.
Today I rolled-on the throttle hard, 3rd gear, at 30MPH - many might
say I was lugging it, but I wanted to get a lot of carb 'action' to try
to get out the gunk, if any. Bike never stumbled, missed, or
otherwise seemed unhappy. Like always, it just "works".
Yeah, it starts a little hard now (it's like 35 degrees most mornings)
but once warmed up it runs flawlessly.

I really. REAlly, REALLY don't want to pull the carb rack for a problem
which might be fixable with some 'magic potion'. I have heard about
some - BG injector cleaner, acetone, Wynns injector cleaner, etc.
Since it never leaked a DROP last year, what would all of you
recommend ???? I certainly don't want to pull/rebuild the carbs
every year! The bike as-is runs SO GOOD it's hard to fathom a carb
rebuild is in order just for a leak or two. I'm a small-engine tweaker
since 1970's, so if it ain't broke I tend not to fix it, especially in
this case where I'm very impressed with this bikes performance.
I'm hoping the seals swell up and take care of things. Till then,
I carry a fire-extinguisher onboard, but leaks SEEM to be getting less.

Hoping for any/all input........thanks in advance........

OK, well 4 days and 3 rides later it ain't gettin
better, so I guess I have to pull the carb rack.
Can't take a chance on a long ride since I don't
want a fire if gas drips on exhaust.

Make sure that you replace the O-rings on the aluminum tubes that connect the two carbs. Did the same as you when I first got my wife's 84, with the seafoam and such. I think it takes away the build up that was making those O-rings hold. Half way through the first tank with the seafoam and both sides developed a leak.

Also, remember that if you are not going to ride the bike for a while, turn the gas off and remove the carb bowl drain screw on each carb (easy to get to usually), let the fuel flow out until it stops and then put the screw back in. That way you have no fuel in the carbs to evaporate and leave sticky horrible messes in the float bowl or block the jets!! Then when you want to ride next time, turn the fuel back on, wait a minute for all the float bowls to fill up and then start and ride!!
