No fuel flow from tank to engine on Husqvarna YTH2348

Its fuel shut-off. I put a manual shut-off in the fuel line coming from fuel tank. No more problems.

Here are a few tips to look at, I would first check your inline fuel filter to make sure its not clogged up. See Page 26 of the Manual for additional help.

Sounds like fuel starvation try each of the following, test to see if it runs after each.
1. Check you have fuel.
2. Check/replace the fuel filter.
3. Check the fuel lines.
4 Clean the carburettor

When it starts to die slacken off the fuel cap enough to allow air into the tank, if it picks up again it is an issue with the fuel tank breather, if the breather is blocked it will create a vacume in the tank and stop fuel flow to the carb.

There is no adjuster for the Husqvarna 450. Husqvarna recommend that if there's not enough oil reaching the bar that you slow down the engine by adjusting the carburettor screw. I have the same saw and also wanted to adjust the oil flow. I didn't change the carburettor and it's still cutting away without doing any damage. It's meant to use less than a tank full of oil to the tank full of fuel when you're cutting near constantly. With stops in between it will use more fuel and less oil.

that unit has a fule pump on it thay rarley go out but last week i had one that the pump was frozen it was cold here and i took it off and put in the truck and warmed it up i asllso found a lot off water in the gas tank so try that if that dosent fix it than you may need to get a new one let me know and tell me what moter it has and ill tell ya the part number ok i may have one in stock ok

clean filters and card ir injector then run fuel system cleaner in the fuel tank

Mine was doing the same thing. Just loosen the gas cap. If its on too tight the engine will stall because the air cant get into the fuel cell to replace the abscent fuel.

Hi..my name is Keith...i would suspect either the fuel cap isnt venting..or if you have a fuel pump..that it is bad..i hope this will help..if not please write back

the float in the fuel bowl might be getting stuck what you can do is push & pull on float to see if it flows if not the replace the float if i can help further e-mail me wade @ [email protected]
