My flip cap on my Stihl spews from pressure just like my screw on caps. Poor tank venting is the problem.

 

Mine doesn't.
At least not nearly to the extent that the newer style screw cap does - that one does it every time.

I keep a rag handy for when I have to fuel up.
Toss it over the cap and open it. Keeps the gas off my fingers.

 

Yep. every time

 

They are tight from the pressure from the heat.

-40 degree ambient temperature helps with this. Move to Kamchatka

 

Yes for trimmer, blower, and kombi. Opening it slowly reduces to mostly only vapor. Keep your hand above the cap to keep it off your hands.

 

But opening it slowly takes time and time is money, so you're cutting into profits by spending an hour a month just opening a gas cap, and...


OK, it's a joke, but you KNOW that someone was thinking it. LOL

I have to use a rag. Opening it slowly is a given, but it "sprays", so it doesn't matter where my fingers are.

I never have this problem with my cordless trimmer.

 

Rag is kept within reach of the gas can.
Sometimes life's biggest problems have the easiest solutions.

 

I HATE that too. The old caps threaded over the tank like a bottle cap so the gas escaped downward. Now they have it spray at the human. Dumbest design they could have made.

And why are the fuel tanks so tiny!?

Yep should spray down.
We get a little over 1 hr run time per tank. On bigger jobs like cemeteries we always fill a coke bottle half full of gas and flatten it so will slide in back pocket. Really stinks to run out of fuel 700 ft from truck.

 

My BR800 doesn't spray much, if at all, when opened (screw in) for some reason, my FS90 does it nearly always if it's over 65 degrees out and it has the improved/2nd gen quick open Stihl cap. My old SH85 HH blower does it most of the time as well, and it is a screw in style cap. I rarely, if ever have this issue with my screw ON caps on my 802 and 8010. Same for my FS250, which is also a screw on style cap.

 

Come to think of it, my BR600 doesnt spray either. Only my km56 did and my now km111 does.

 

Never had this problem and was a stihl fanboy. I do wait to fill them until they are almost empty and fill when I thay have cooled at the start of a lawn.

 

I never have any trouble unscrewing the cap on mine. The only problem is gas spray.
I hate the smell of gas and it doubly sucks if you want to pick your nose afterwards.

Thats why I open the cap with my right hand and only pick my nose with my left lol

 

Yes, all of my handheld stuff does it, not just Stihl.

 

Yeah it happens ALL the time. The pressure also seems to make it so that the caps are impossible to remove, I normally just use some needle nose to take it off.

 

Ha, same with the push button fuel cans, if you dont let the pressure off, the fuel shoots out like a firehose.

 

Yeah, I strategically get a quick fill! If I don't screw it up!

 

My redmax never did this. Stihl always

 

Mine did that, it was an issue with the tank vent. Eventually the vent got bad enough that it would cut the units off when it used all the air in the tank. New Stihl vent didn’t fix the issue, my dealer also sells echo products and he fitted an echo vent on my stihl

 

I actually added a vent to my 029 saw because it wasn't venting.

 

stihl gas cap should never vent...theres always a tank vent valve that does this and its one way to allow air in the tank...all stihl gas caps are designed to seal the tank...if leaking time to replace them...if tank isnt venting them you need to fix the tank vent...this goes for all stihl 2 stroke engines

 

I have found that the spewing is “normal” even with a good working vent. All 3 of my NEW Stihl trimmers have done this.

When the vent goes bad, you usually get an air filter covered in gas. As the vent on my Stilhl trimmers vent into the airbox.

I do agree, the cap should seal.
