Fuel Valve warning - dell orto

Just to let you know that we have lost 5 hours today between two men.

we have had a Husaberg in that needed the carb kit to spruce it up a bit. so usual job, needle, atomiser, fuel valve etc, etc.

we put it on the bike and as usual it leeked a little but we tried to carry on as the vibration of a started bike normally settles the fuel valve and beds it in.

however, after two strips and perfect cleaning we still had the trouble.

in the end I fitted a clear float bowl I have never used in the 30 years I've owned it and basically, even though the float arms stopped the fuel valve at parallel it carried on leeking up all the fuel vents.

so, taking over from the mech I went back to the fuel valve, removed it and then it's 1MM fibre washer.

WELL, IT ISN'T A 1mm FIBRE WASHER! IT'S A PAPER GASKET AND IT IS 0.4MM THICK.

you multiply 0.6 difference by the distance to the end of the arm which is what? about 6 or 8 times to get to the tips of the float arms and that means that the valve is closing nearly 3mm later. I was really surprised at Eurocarb UK's attitude. they couldn't give a monkeys and he said that they would carry on selling them like that because that is how they are supplied!

we lost over half a day to this simple error. couldn't find the dell orto italy e-mail address to give them a piece of my mind.

please pass this info on to anyone whose bought a fuel valve lately. this was fresh stock for me this week so I hope I caught the first one this at the first one....

use the old fibre washer.

that is all

this is a very technical issue and we are way over the heads of at least 50% of the people here.

lets get back to gearing....

well you could be on the verge of your stator packing up?

but other than that the carb being worn out is an obvious choice. at least it is relatively simple to do!

do the cheap things first. I trust you realise I do a kit for these?

the keihin is a slightly better carb but what you'll probably find is that it is a carb converted from another bike!

as for the rebuild well they obviously weren't experts or they would have changed the fuel valve as well.

cheapest option is to send me your carb and I'll recondition it for you OK?

there is a lot of work involved. 2-3 hours work. anyway: up to you?

I would repair yours first everytime.

a keihin with jetting kit is about 225gbp and a 39 would be perfect for your 600.

Not today but soon I will quote you via the email system.
