Chainsaw Repair

I'm just posting this info from a stihl dealer on my FB Chainsaw Repair group.

copy and paste usable or not.

In many cases it's the melted welch plug sealant that causes the problem. The latest carbs have stainless welch plugs that don't need sealer.

On the issue of whether to rebuild a carb. The newest carbs have ethanol resistant components that older carbs didn't. Like stainless steel jets and welch plugs. If the new carb is only 20 to 50 dollars it is a dir servive not to change it to a more serviceable component.
