85hp Force - 1989 - Model # - 856X9G - WOT Bogging
Issue is, will run great at WOT for 20 seconds then descend bog up an down, finally settling down to 1/3 speed, full throttle.
Will do fine at idle, under low speed and 1/3 speed.
After the WOT bog down, will not perform same trick to get up to full speed for at least a few minutes or not at all.
Shut engine down, let sit for a few moments. Start again. Can perform the same trick, with same behavior dependently.
Acting like a fuel issue. Feels like a flooding issue. Again. Not sure.
Does seem to idle kind of high though. Need to figure how to measure RPMS with tachometer. ( would favor a permanent tach install or just easy tool, Either. )
Checked fuel lines - seem adequate fuel in inline filter before carb.
( Water separator used after tank )
Changed Plugs & Boots. NOT Cables or Power packs ( packs appear replaced )
When carb tuning - Adjusted Idle Carbs to 1 turn out, does well there.
Air / Fuel mixture screws ( not sure if correct ) on face of carbs are set completely in when i got it. Ran fine but had bogging issues when engaging low gear
.
General Owners manual says set 1 turn out, doesn't make a lick of difference. There's also no needle parts of the screw.. Just brass mixture screws. I believe. Still not sure.
Carb butterfly flaps and link rods appears correct.
Still haven't found a very specific shop manual or the best of best shop manual for this engine. Feel like it could clue me in better.
