Walbro HDA 191-1 for 346xp?

[sunfish]

I see the Walbro HDA 191-1 carb is a replacement for the HDA 199? Does anyone know if the 191-1 is any good? Found a new one for a reasonable price.

I have a newish Zama 357 replacement on a ported 346 that is giving me fits. It idles and cuts fine, but will not idle right after a long cut. Seems like it runs out of gas? I have messed with the metering leaver and tuning and can get it better, but just can't do away with the problem. I'm bout ready to chunk the Zama.

Having trouble finding a reasonably priced good Walbro 199, sent a bad one to Scott (Treemonkey) that I couldn't fix. No word yet. Saw couldn't be tuned to run over 11,000 rpm with this carb?

Any help would be much appreciated.

Sounds like a possible tank vent issue.

Will check, thanks! Never had a tank vent issue, so never gave it a thought.

Buddy of mine had a Jonsered 2159 that started acting up and was the 199 carb issues, and the dealer replaced it with a 191 and so far no trouble.

Good to know. I've never read anything on the hda 191-1, but I'll have one in a few days.

Tank vent looks OK, but cleaned it real good. Too hot and no wood close to the shop to try it right now.

Too hot here as well, but its these days we can still TALK saws.

Ran this saw a bit today and no problems. Guess cleaning the tank vent helped? Might need to modify the vent to get more air in there.

I will say this saw will likely never see .325 again, as it pulls 3/8 chain like a high speed train!

Beautiful saw!

Say that again as I grin real big.

I'll keep a longer .325 bar on one and 3/8 bars on the other two stronger 346s'.

The HDA-191 is the version for heated saws (357xpg/2156WH and 359g/2159WH), but basically the same as the -199. The -198 and -190 are the non-EPA versions.

They likely all share the same potensial issue.

Good to know that, Niko. Thanks!

Well, the 359 Zama replacement runs good on this 346xp. But I'll put the treemonkey HDA-199 on and see if there is a performance diff. Then I'll try a new HDA-191 and see how it does.

Tried the 'new' HDA-191 & the Treemonkey 199 today, both ran like crap! Tuning made no difference.
Put the Zama back on and runs great! Weird **** here?

I wonder if it was actually Treemonkey who "fixed" the carb........

Well I sent it to Scott, but I wonder also?

I might of spoke too soon. Put the Treemonkey 199 on a 357xp today and it ran fine. Back on the ported 346 with a little tuning it now runs fine? And to top it off, the new Walbro 191 runs fine today also? Like I said, weird stuff!

Don, Did you ever get this sorted out? I have issues with a 357 seems like it runs out of fuel sort of. I have already gutted the vent. Could be the coild getting hot and breaking down??? Have you ever tried the vented fuel cap? Thoughts

Having the same issue with my 357. In a 20in log it will just die out like you said like it runs out of gas.
