change the spark plug,dump the old gas,and toss a half acan of Seafoam in the gas,and a little in the oil(as per directions/volume).You may probably want to dump the oil first putting in hd 30,use it twice and dump,then put the seafoam in again.I would be surprised if that didnt work,that stuff...
slam a couple cans of seafoam in acouple gallons of gas(new),and put the old in gas containers for disposal when you find the right/safe solution....if you part it out O need the gas tank filler neck...Peter
check if gas smell from underhood or rear at evap lines running into tank
was it the recalled gastank or you missed the recall till now?The vin at the dealer will tell you if the tank was replaced or not,and the rear seat belts......Peter
curious because Im having a vibration problem after ujoints d/s balance,3rd member etc.mine is also lifted,and seems to do it at a bottom of a hill,in the summer,yet not all the time....Peter**** NICE RIG!
