029 to 039 carb

[Tumleweed66]

I saw somewhere talkin about the fixed jet replacement for the 029 to an 039 build but can't find anything on the original carb on my 029 which is the Walbro HD 5...
Can the fixed main jet be replaced in the hd 5 and if so what should go in it for the 039 or is there just a way better option for carbs that just works better for the saw all the way around. I used new oem 390 p & c and hate to screw it all up, any help is appreciated.
thanks Mike

Don't need too 029/290 carbs run 390's just fine. Done several.

Not an issue. It might equate to 1/16 - 1/8 turn more on the jets
