• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Carburetor Leak (Storing Bikes for Summer)

Today I filled up my daughter's Honda TRX90 quad for first trip of the season. Had massive fuel leak from the carburetor. Gasket on the bowl. I stored the bike empty all summer. Did I do wrong? I always use fuel stabilizer.
 
Sometimes the floats will stick open. Did you try whacking the carb with a rubber mallet? Sometimes that will jar the floats loose. If that doesn't work, time to inspect the carb, make sure it's clean and all the parts are in good order and not damaged or degraded in any way, especially the tip of the float valve needle and the float valve needle seat o ring.

Correct me if I'm wrong, but I believe he is saying that the actual float bowl GASKET is leaking. That has nothing to do with the float valve. If the float valve was leaking, or stuck, he would have a never ending puddle stream coming out of the overflow tube and spilling on the floor below the bike until the tank ran empty(and keeping the motor and carb dry). What causes his problem (the bowl gasket leak), is the expansion and contraction of the gasket. I see it happen all the time when rebuilding/working on street bikes and dirtbikes. The new fuels have a lot of additives and alcohols in them that make the gaskets soften and swell up. When you remove the gas, the gasket dries out and becomes smaller and brittle. When the gas is re-introduced, the gasket won't seal UNTIL the gasket swells up again. There is a limited amount of times the gasket can go through this process. I have seen this numerous times with both carb bowl gaskets and petcock gaskets. They all leak profusely at first when they are old, and then by the 2nd or third day they are tight and will stay this way until allowed to shrink again. If it's bad enough, they will never seal and will always leak.
 
Yes Soviet, that is it. The float valve may be stuck too but gas was coming out all around the bowl.

Well, i'm guessing if you let the gas sit in the carb for a day or two it will stop leaking unless the gasket is completely shot. I usually turn the petcock off so it doesn't leak too badly and then let the fuel and vapors in the carb do the work. Usually stops leaking in 6 hours-3 days. The float being stuck will cause fuel to drain out of the overflow tube and it will never stop until your tank is empty.
