Ht131 air filter getting soaked in fuel

Ive noticed the fs 70s shafts bend never really seen strimmers do that before I might try swapping the engine out for a fs 70 on the 4 mix if it ever dies its never let me down yet.

Replace the breather valve (already mentioned). I do this about a dozen times a week!!. 4mix will never start with a wet filter. I hated them when they first came out but I like them now!. Get the valve setting done at every service, change the impulse hose and breather on a regular basis and relax!

I can't see that Stihl have changed their production method for this one model of strimmer shaft (which is still the same type and diameter as every other model below the FS310). Therefore I would suggest that you have a higher than average percentage of heavy-handed idiots working at your firm

 

A shaft won't break due to too much cord- that's what the clutch is for.
