Stihl fs46 Acting like it is not pulling fuel from the tank.

[pfunk76]

Hello,

I have owned the fs46 for about 8 years now. A couple of years ago I had to have the trimmer at 3/4 choke in order to run the trimmer after it had warmed up. There turned out to be a crack in one of the pickup hoses going into the tank. The hose was replaced and all was well.

Recently this started happening again only this time there aren't any hoses with leaks in them. There is also no adjustment on the carb except for 1 screw that I believe controls the idle. No matter what position I had the screw in the trimmer would only run if it was at full throttle which is making me think there is not enough suction to pull the fuel from the tank at low rpms. I removed the hoses and checked them from blocks and blew through them and there was no resistance.

Any Ideas

Maybe a cracked primer bulb or it isn't sealed very well.

Try some lead right above the spark plug hole.

Eight years is like 56 dog years.

Time for retirement.

No crack in the bulb.

Time for a carb rebuild. You fuel screen could be clogged. 10 bucks and an hour to clean it well and rebuild the carb.
