What 028 Carb do I need?

[kd460]

What is the number (or model, or type, etc.) of the the Walbro carb that I need for a Stihl 028 Super?

I know the Tillotson HU is for the standard bore 028, but from what I understand, 3 different carbs were available, and I would like to try and locate one of the carbs that came with the larger displacement 028's. From what I have read, the larger carbs that came on the 028's are the Walbro.

So, I want to do a "carb and pipes" modification to my 028. It was originally a 42mm bore, and is now a 46mm bore, so I feel a carb and pipes will really help thing outs. Just need to know which carb to search for/get. Thanks, KD

Anybody know what type of carb is found on an 028 farmboss or a super so I can start looking for one?

Found a few numbers, but not sure if they are the right ones or the differences.

Walbro wt16, wt16b, k20 wat ???

Both of my 028 Super's have a Walbro wt16B.

k20 wat is the carb kit part number....

The results you are looking for will likely not be obtained by a carb change.

Do a search, or post a thread on 028 mods........

Actually I search the 028 threads fairly often. This is what led me to the question.

I read a post describing the different carbs for the av, the farmboss and the super. From what I read, a reference was made that the tillotson was the smallest bore, and the walbros were larger, for the larger displacement 028's.

So my natural thought process is, I have a super cylinder with the smaller tillotson carb, so maybe I would get gains (move more air) by switching out the carb and doing a muffler mod.

From what your telling me (fish), the carb swap will not help anything?

Scooterbum, thanks for the confirmation.

I still plan on doing to do the muffler mod.

Thanks for the info/replies. KD

I don't know about the gains, as the Stihl parts lookups do not get too specific, and just supercede to whatever is still available.

Exploring the Walbro site, you might find a carb with a bigger bore, and
swap out the throotle and choke rods, so the linkages will work ok.

I will plink around with that.
