right then,
i have a stihl fs76 trimmer that does not work. it will start and run for a few minutes then lose power and die.
good bits are:
new diaframs in the carb,
new fuel filter,
new piston rings,
new base gasket,
checked the fuel lines,
compression is good,
spark plug is dry whem removed after its cut out,
new plug doesnt help it,
spark is still strong when the machine has cut out,
tank cap is clear,
bad bits are:
worn butterfly in the carb,
some vertical scoring on the piston and the barrel,
evidence that the piston has seized at some point in the past,
evidence of overheating,
the bad bits may provide some clue as to what is causing it to fail although all those problems were present when the machine was working fine.
i cant figure it out - can you?
