The engine will only run fully choked, removing the choke will cause the engine to die. It seems as though the fuel supply is restricted. I checked the function of the choke, seems to be working correctly. I replaced the fuel filter, no change. The engine has approximately 80 hours on it. Any suggestions would be appreciated.
Had one on my saw mill had this problem as well Try pulling bowl off bottom of carby as the float can get **** with old fuel especially ethanol fuels as they attract water bowl is normally held on with one center screw on bottom of carby. Note always turn fuel off and let engine run out of fuel as this stops goop from building up in carby
Thanks for the help - found the problem it was a perished fuel pipe between the pump and the carb, the inner rubber pipe was causing a blockage where it was slightly bent. new piece of hose and now all OK
