Try putting Power Service diesel additive into the fuel. It seems to have helped
mine out. Run's a little quieter and it's got more pep. You can get it at Walmart
and alot of other automotive store's(WallyWorld's cheapest).Get the grey bottle
of P/S it has a higher cetane rating than the white bottle. Yes there is two different
bottles of this same product, the white bottle has anti gell formula for cold weather
with a slightly lower cetane rating. If you think about it while you are there pic up
some marvel mystery oil for and add a little of that to the fuel also.I have been doing
this for some time with no ill effects(Truck & RTV) P.S increases fuel mileage also
not that the RTV need's it.
