'86 125hp 4000 rpm wot

[Kcoll]

Just wondering if anyone could help me out with some ideas. My engine was only running at 3000 wot, new plugs, timing adjusted (it was retarded by 4 deg.)which smoothed out the idle. Compression was ok, sprayed some carb cleaner and it bumped it up to 4000 wot. I noticed the top carb leaking a little, and figure they both took in some of fuel through the air intake. I am assuming they are to gummed up for the carb cleaner to take care of it, so I pulled them off to clean and rebuild. I am curious if everyone agrees or if there is something I am not thinking to check. Also how hot should the exhaust water be? Thanks

Exhaust water is generally hot.<br /><br />Take the front covers off the carbs and advance the throttle all the way to WOT.<br /><br />Check to see if the throttle plates are open all the way.<br /><br />Post compression Numbers please.<br /><br />Next check for fuel line leaks.<br /><br />TMD
