I just had my Carbs rebuilt on a 2000 Yamaha F100 with 4 carbs.
They charged me 5.5 hours (that is ex diagnose and running etc.)
Is that about right time wise?
1999 F-100 LTRY 67F L 306064
110 Hrs only.
Initial problem was stalling in midrange 2K to 2700 rpm,when throttle was advance slowly.
I adjusted the mixture and it got a little better.
After a while the engine sputtered at idle, like backfire through the carbs?
Replaced the sparkplugs with ngk...
