Stihl fs 85 weed eater trigger replacement - Stihl FS 85 Weed Eater

Carb jets need adjustment.

Maybe this can help you

could you add a picture of the particular head you're using.

Try loosening the gas cap to relieve any pressure, then tightening it back up. Usually you will just need to barely unscrew it and then screw it back even before you pull the rope.

Im figuring the FS85 has the cow horn bars,of which there are 3 types of controls. Here's the Illustrated parts list diagram. If you would like the full IPL please contact me further and i will send it to you.

easy... if the carb adjustments are still factory set the you just need to replace the muffler screen or also called a spark arrester.it covers the muffler exit....

older models have a pick up and condenser for spark. newer models have pick up and ignition module. the pick up rust the condensers and modules go bad. first take apart to expose flywheel then ck for rust on flywheel at pick up if rusty clean set pick up clearance to that of a matchbook or ten thousands of a inch.if still no spark change condenser or module.

check the cable at the carburator and at the trigger itself probably is disconnected or broke

sounds like ur shaft inside is bent
