i have an 89 force 35 that i am trying to tune.
the book says idle should be at 600-750
when i set the idle this low the motor really wants to choke and sputter, and 1/2 the time will stall when put into gear (the shifting is super smooth at this rpm, no clunk at all) - at this rpm the motor doesn't always want to restart and will take 3 or 4 key turns.
when the idle is set at around 900-1000rpm - it starts and restarts on the first key turn and runs great, but when put into gear there is a slight to moderate clunk when engaging (should there be any clunk when shifting?)
what is going on - is my motor just one that likes a higher idle setting?
could my books #'s be incorrect?
is there another carb adjustment to make?
Other than the idle issue the motor runs perfect at any throttle input
i recently installed a tiny tach and i seem to be getting consistent readings- the tach will bounce up or down 10 to 20 rpm every few seconds but for the most part it seems to be hooked up properly (red wire wrapped around the spark plug wire 5 times)
I have just done a 3 part seafoam de-carb and have new plugs installed
thanks for the help
