Walbro HD199 Fix

blsnelling · May 3, 2012

We've all heard about the troublesome Walbro carbs on Husky 357 and 359s. I have a couple here that are acting up as well. I've heard of several people trying to fix these. Does anyone have the lowdown on how to do this? IIRC, it's related to the accelerator pump wearing out. How is this bypassed? I know how to do it on the 200T carbs, but not on this one.

I've talked to several Master Husqvarna technicians and none of them had an answer. A fix for these hasn't even been addressed at the Husky dealer meetings.
So I'm not sure. I threw the two junkers I have in a box thinking someday there may be an answer for them.

I figure the money I make from porting you guys saws is enough. If I happen to figure it out, you'll all know how to fix them. I don't mine giving back to the community.

What is odd is that the IPL of those carbs don't seem to show an accellerater pump? :msp_confused:

I suppose that simply means it's not a "replaceable" item.

Here is a link on how to repair HDA 199. Haven't done one all my 199's are working good. Link deleted due to redirecting to a competing forum.

It doesn't look like he's tried the carb yet though, so the fix is untested.

You have nothing to loose except some time carb is no good as is.

What do you need to accomplish your offer? The whole saw or just the Walbro carb shipped to make the 357xp or 359 saw run better than new?

The new repayment Zama is only $40.

Walbro supplies no part number for the accelerator pump kit on any of their HDA carbs that I can see. Shows on the IPL but there is no part number associated with it, so I assume they treat it as non-replaceable.
