Timberwolf 150 running problem

[ARBORPRO TREE SERVICES]

Hi my chipper keeps dropping to half revs and stress kicks in its 99.9 % water in fuel as when clean fuel tank out and put fresh fuel in it runs fine but it's happening twice a week got gen fuel cap was wondering if anyone else has had this problem I wondered if its the seal around the metal plate on top of the fuel tank where pipes go in letting water in when it rains any suggestions cheers

sounds like a fuel restriction of some sort when it does it try pumping the lift pump and see if there is air or fuel coming out for starts

i assume new filters as well. has happened my tw a few times (water in tank), but more than a year between times

Could be condensation forming in the tank, you need to keep it full. Re seal the metal plate with the filler on. Check the fuel you are putting in.

Have you bled all the injectors and pump ? Whether can in timberwolfs or if it's aurto bleed. Also check for small blockages anywhere from the main fuel line to the tip of the injector, I run a fuel treatment through my chipper once in a while. Failing all that you might need your pump/injectors tuning.
