motor issues, carbs dirty maybe?

[2182]

this does make the most sense (starving the motor). i checked all the fuel lines from the pick up back last fall (when i replaced vacuum switch), all was good. at that point i replaced primer ball. i always check the fuel in the separator when i change it. this time had some lovely metal flakes, but no water. guess i will recheck fuel lines, add splice in place of fuel management filter, and try to water test. if that fails, motor is still under warranty, and she goes to the shop. the joy of living on the coast is this time of year there is a 2 week wait minimum at all mechanics, even the country guy i use in the middle of nowhere...thanks as usual for all your ideas and suggestions, ill keep you posted.
