Interesting stuff happens around here don't it?

I still like to smoke a Monte Cristo when sawing.

Now that could start a trend.:tongue2:

Any new developments in dealing with the HD199 issues? I see these saws on CL often and would like to be able to fix the 'carburetor issues' (that are often mentioned in the listing descriptions) if I buy one to 'fix and flip'...opcorn:

Yep. Scott (treemonkey) fixes them and does it at a great price.

I used a couple of his that were perfect.

 

[blsnelling]

I just send then to Scott as well. You can't beat the price.

 

[LowVolt]

He did a 357 xp carb for me and it ran perfect.

Anyone hear from him? I saw a thread in the past few days asking if he was ok. Any word?

I was trolling here, but one of those dang moderators edited my post and now my keyboard smells like cheese and bratwurst.

Any chance the nozzle is the issue? Easy fix. http://www.arboristsite.com/chainsaw/145468.htm

Some real good troubleshooting here to find out where you're problem lies.

That's what I'm thinking the issue is as well. They are an easy fix, I've done a few Walbros already, the check nozzles usually cost between $2 and $5. Walbro also has fairly good tech support. The parts site is also handy and has a distributor locator on that page as well:

Great link that deserves repeating(thanks maico490):

Forgive me for going way out on a limb here, but I'll take a SWAG that if simply replacing a faulty nozzle was the solution to the problem, Husky would have chosen that approach in their tech bulletin on the matter instead of determining a carb swap to the Zama was the better way to go. May have been PR and/or contractual components at play for such a decision, but most who have transitioned to the Zama are less than enthused about that approach as well..., at least according to what I've read so far on the subject.

Then again......., mebbe a freekin' nozzle replacement on a "bad" HD199 fixes everything. Then again again, would probably depend on the production run of the nozzles, now wouldn't it?

Gotta be more to it, but it can't be much. I'm just surprised there's only one guy on the planet with the magic bullet to fix these things...not all of which are lemons btw, (and that's according to Husky, not just AS posts), though they have been said to fail over time. That indicates material failure, not design failure.

Also kinda funny that the same bulletin didn't include other saws with HD199's, namely 346XP's...unless I totally missed that tech note.

Both my 357XP and 346XP flat out scream with stock HD199's. I'm hard-pressed to find an issue with that.

I too am going out on a limb. But, consider tech time on the fix. Would it be worth it to just replace the carb? I don't know. Just asking.

Tech time increase to replace the nozzle vs. replacing the whole carb would be negligible if the tech had a clue. Price difference between a little brass nozzle and a whole new carb, not so negligible.

Since this thread is over a year old, and was pretty controversial at the time, I'll go out on another limb and suggest a few other guys have figured out the mystery fix and have deferred to Tree Monkey as the "go to guy" for this out of a sense of professional courtesy, and hopefully, an acquired sense of professional maturity since the last time this whole thing was hashed out....maybe even because of the last time it was hashed out.

At least I'd like to think so.

I sometimes need a high speed jet added to a 3120 carb......I send it to someone else. That way I can keep porting. The WT-199 is other carb that I send to have done. If someone has taken their hard earned time and learned how to do this.......I'm all about helping them make a few buck from that knowledge.

Yep. That was the point....again.

If said person can fix the carb for $25, that includes a new kit and testing, do you really think its anything special? I don't. He can withhold any info he wants, I don't care, I'm not like that however, if I figure something out I'm more then willing to share with others.

There is more going on with the fix about swapping carbs, sometimes it's just he easier thing to do, with no messing around, that's worth allot to a shop/business, then the tech can get going on the job quickly, it's not always about the fix that's worth the least amount of $$. If it saves one comeback it's worth it to the business.

The problem that the Walbro 199 had that was the reason for replacement was an inability to transition from idle to WOT, not fixable with the hi/lo adjustment or a standard Walbro rebuild kit. Most times the saw would start and idle just fine but could not get to WOT throttle without the use of the choke or trigger feathering, eventually it would just not transition at all.

Some of the saws straight out of the box had carbs that were very iffy and did not take long to fail. Many of the Walbro replacement carbs failed in the same fashion.

When the problem first starts to present itself it may be "fixed" by a readjustment of the hi/lo, possibly a kit, sometimes that would last for a good bit. Many of the carbs that have been replaced have had the limiters clipped or removed. Many have almost new carb kits in them.

If carb is flooding out or will not idle and no non factory carb modifications have been made then that is a different issue.

Most of the carbs do not have a worn out A pump, the circuit is just plugged.

Buy the Zama.

I bought my Jred 2156 new in 04, never had any issues with the Walbro... I'm feeling pretty lucky, might have to buy a few lotto tickets at the next gas station.
