Stihl 041 Carb Problem
« on: December 21, 2011, 09:39:23 pm »
i just bought a carb and some other parts (to get my new to me 041 farmboss stihl going again) from a fellow on Arborist site.the carb bought has been rebuilt and cleaned before shipped to me.but one problem i got is when i start it and try to retune it like he told me too.it don't do nothing but over load even when both screws all the way in. and it never does get full throttle.but it will set and idle for about 10 to 12 seconds i guess and then choke out.i knew how to post a video i would post one.but it will spit mix out the top of the carb and out the muffler. i'm about to the end of my ropes with this thing. i'm about to take it to the stihl dealer tomarrow and see what he can do.But i wanted to come on here first and see if anyone knew what i can do to get it going like it should.

Sounds like the metering valve on the regulator side of the carb is stuck open or set up wrong?

This is a layman site and he calls the metering valve of the regulator the needle valve

The Tillotson is set up pretty much the same as a Walbro

You need to know which model Tillotson you have like a "HL" for example
