Re: Stihl 048 AV - Runs Very Rich... Need carb rebuild?

Hello Al Smith

Well, that sounds Very Interesting. I hadn't thought of something like that being the issue. I don't know the history of this saw, nor if the carb has been rebuilt before, but its likely.
I haven't taken the carb apart yet, as I didn't have a rebuild kit for it, so I didn't want to damage any gaskets or other if it wasn't the carb that was the problem. At this point though, a problem with the carb itself seems to be the only thing left.

I think I will order a rebuild kit for it today, found an OEM Walbro "Repair Kit" on ebay.  Which is basically a Rebuild kit + the Inlet Control Spring.

Going to try to find an assembly break down diagram for the carb. See if I can look at the diagram as I take the carb apart, and find any thing that looks to be out of place or in the wrong place/position.
I'll pay special attention to the diaphragm and the spacer. If someone has rebuilt this carb before, it could be the very problem just as you said.
I have a ultra sonic cleaner with a heater, so I might take all the carb parts and put them in there and let it run for a while.
Don't know if I can get to it today or not, but if not I will sometime this week.

Thanks for the Reply & Info
