My husqvarna trimmer keeps leaking gas out of the carburetor. I just got done cleaning and rebuilding it, new needle and lever also. It still leaks gas when I prime it. What is wrong with it

I have rebuild probably 15 carburetors in my life. I know what the fluck I'm doing, (I'm stealing your word also) and I just wanted some advice because I don't know what's wrong. Do you really have nothing else to do but be a ass to people that you don't even know?

It's like Deja-Vu all over again!!!!!

IF you rebuilt it, AND you know what your doing, then WHY is it leaking gas?????

Ya oughtta just take it to the same shop you took your chains to!!

They might have somebody that knows what the fluck they're doin!

I don't know why in the hell it's leaking gas, maybe that's the reason I'm asking????:hammerhead::hammerhead::hammerhead::hammerhead::hammerhead::hammerhead::hammerhead

I'm surprised you found a rebuild kit. Most carbs are meant to replaceable these days. Chances are when you removed the covers they warped or when you put it back together you overtightened the screws.

It is actually a older trimmer and someone put aftermarket carburetor on. I thought that the needle was the problem, but its not. I was hoping it would be something simple because I really don't want to put more money into it.

With a name like 2stroked, I figured you'd be the one telling us how to fix carbs....
I'm gonna have to agree with Patriot on this one,,, Most 2 cycle carbs do not improve when you install a kit in them...they used to ....but not anymore. Ethanol and poor engineering are taking the tools out of alot of mechanics hands.

Try not to piss off FISH...once he senses splashing in the water...Oh Well...

It may just need a twik on the needle actuating lever. It is probably too high and hits the rubber diaphram. Funny how I aslo assumed that new parts would fix that but after 20 years I figured out how to bend that lever a little and it works. A lot of failures are i the other direction where you havfe to bend it up.

Did you attempt to replace any of the welch plugs from the kit you installed? I almost never replace them and the reason I ask is this could be a missing or leaking plug within the carb when you prime. The more likely cause is the metering lever needs adjusting, I almost always use the old one which was adjusted at the factory and saves time. OR the metering diaphram and gasket were put on upside down. Another thing to look at is the plumbing for the fuel lines from the tank, to the primer, to the carb and from the carb to the tank. I believe you husky has a remote primer, right? Make sure its sucking fuel through the carb NOT pushing fuel into the carb. Good Luck.

I will probably take the carburetor apart tomorrow and reinstall the old metering lever. Yes, it is a remote primer, I looked at it today and realized that it is pushing fuel through. The way that i have it hooked up right now the primer is pushing fuel through the top inlet of the carb and the fuel dump line is hooked up to the bottom of the carb. I'll try to get that straightened out tomorrow

You know, it would be nice to know everything, but I don't and the one had me really puzzled. Oh, and about fish, I really don't care (it's sort of funny). Maybe I'll create some more threads just for him:laugh:

The fuel lines being reversed could be causing your problem...
Cleaning a carb properly is alot more involved than soaking it, this can actually eat the sealant off welch plugs and make them leak (flood)

Back in the 80's (yes I have been working on small engines that long) there wasnt a carb that couldnt be repaired by a good soak and a kit. You really need to understand whats going on inside the carb ( where all the fuel and air passages are, and why they're there) Find some good Zama and Walbro flow charts and try to make sense out of them. At least get a Walbro pressure gauge to check for leaks.

Yeah Dude...He's still lurking....

Fuel lines were reversed :rolleyes:. Fixed the carp today and it is running good. It's pretty powerful for a 22cc. Thanks for everyone's help.
