I don't remember any. my friend Allen was pretty experienced withthe float bowl, as he just went through a incident on his Honda Accord, where the floats were bad... so it was fresh in his mind to check it...

That makes sense. I read something somewhere (probably this thread) where a guy was having the same _orginal_ problem after he hopped up the bike, and it would blowback into the carb, and even get the air filter wet, and suck it into the carb...

I found a few adjustments in the shop manual I have. Only one of them I was able to understand/do without special tools. It just entailed adjusting the slack in the oil throttle cable. Apparently there is a little screw thats supposed to line up with a make on the oil pump, and it wasn't... So lined it up, and it runs much better now...

> you have and are you sure it is completely off?

I would say so, yeah... the choke lever is pulled all the way to off, and the choke cable seems all the way down. (moving it up, kills the engine)

I also took the exhaust off and tried cleaning the exhaust port. it wasn't plugged, but the whole thing, and the pipe is caked on the inside walls. I scraped what I could/reach....

So now im back to the orginal problem of stalling/flooding/cutting out/ drop in power (whatever you want to call it) at about 24mph.... Getting over 20 now, but still not getting what I used to....
