Trouble diagnosing carburetor problem

[seattlecb360]

Hi there,

Not sure this is a carb problem but the bike is revving great from idle when I pull throttle very gently but fast throttlekills it and it ends up flooded.

New plugs at Clymer manual gap spec, valves at factory setting, new oil, strong battery.

Any ideas?

I should also say I've been riding it all winter and it started bogging down at 4-5 rpm, losing almost all power.

Seemed to be getting worse.

Synched? Just a guess, but you need to get all the obvious stuff out of the way

carbs a little out of synch wont do that and unless you screwed with that adjustement they should be fine
the motor sounds weak do a proper comp test before you do anything else
on another note you cant really just instantly jerk open the throttle from near idle and excpect it to come alive instantly so stop doing that it is not a good test
make sure the advancer is working like it should,point gap and timing is set
you need to set the timing with a light at 3500 rpm+
