I just set my valves on my BD 4500 the other day. they were way out. .008 on the intake and .015 on the exhaust. I set them all to .006. Since the adjustment I have notice that my motor seams to be running rich. Plugs are black, and if I run for a while, shut it down, then try and start it a couple minutes later, it is hard to start. Is this a common thing? how would I go about adjusting my carb to lean it out a bit?

Does TDC mean anything to you?

does burnt fingers mean anything to u. dguidry bubby83 try setting ur valve lash on the back side of the lobes it is in my opionion a better way of setting lash do a search.

What was wrong before you "fixed" it?

running to lean

Yeah, I saw where you posted that but the motor wasn't running like shit before you messed with it, right? What else has changed?

no more valve clatter.....

if you set your valve lash to exact specs. i would think that your rich problem was already present.you might be just noticing it after the fact. i would rejet your carb install new plugs and run a test on it.

Maybe your prop too. That could cause it.

i'am i missing something here. or are u in one of your moods cb.

No problem other than a little clatter...set valves...PROBLEMS...

Only one thing changed on this motor to make it start running like shit...I'd start with rechecking the only thing that changed...

Think simple, stupid!
