I'm looking to put a bigger carb on my 346, I'm thinking of getting a Walbro 191 which is the same as a 199 that comes on a 359. Will it bolt right on or do I need to change more stuff.

Yes, it works fine. Have one on a 346 now.

Might as well add the 359 intake & better air filter at the same time, flows more air

198 Walbro works fine also. Few on Ebay right now.
Does t
Does the cover still fit??? Or do u have to use 359 cover???
How much improvement would I see on a ported saw with that carb, saw already runs really strong.

Don't know how much it adds on, I did all of it at once. Brad has pictures of his 346 top on, mine was on a 2152, I think the air filters are the same overall size or very close, just more inlet air area on them. The new filter neck is like $15

It's a noticeable difference. All my 346s' are running 357/359 carbs now.

The 346 intake is larger at the cylinder end, but the 357 intake is larger at the carb end. So it's wash there and to me not worth changing. The filter and filter neck are larger on the 357, but I stayed with the 346 filter set up.

Is there any other difference from 190,191,198,199 other then heathed & EPA?
So it is a straight carb for carb swap out??? The 346 manifold and air filter will fit onto the new carb without large hammers, torches, grinders, or pry bars???

I run the 191, 198 & 199, doesn't seem to be any difference.

If you search for Brads thread Heaven something he had some really nice pictures of it all in there along with his porting work. Save the torch for the muffler mod
