Steve,
I like a challenge! I've gotten rid of all my bikes that I liked to wrench on so I have to have something to do at the workbench.
I used to love to bring home old Hondas and fix them up to sell but the market is so darn soft I can't hardly seem to break even on the resale.
Tonight I dug out another old Honda bowl and made it leak....then put a bead of solder around the base of the tube...so far so good.
Gotta travel for the rest of the week so it's sittin on the bench covered and with some test paper under the nipple...will check when I get back home.
I suppose I'll get tired of smelling like gasoline soon, surrender and send my bowls to you.
I know the heartbreak of hydro lock. Had a friend leave his perfect CBX on the side stand with the petcock open last summer...one touch of the starter button in the morning and the #1 rod turned into a pretzel.
Barry in Cloudy Wisconsin.
