How many turns are you setting the pilot screw?

Just had an episode of bogging down and poor throttle response...
Went down the list:
Good flow from the tank,
Checked the carbs, float valve filter looked like the lint trap on my dryer (wonder where all that crap came from?)... :oops:
All cleaned up, inline filter installed and it's running well again.

Question is on the pilot screw setting.
I counted the turns to closed (6.5) before I removed it for cleaning.
Put it back in that way.
Checking the manual (2.5 turns) and searching the forum (5-6.5 turns).

It's running and idling fine. I just don't want to cause any problems with it being too rich??

Thanks,
Bill

Bill,
Shouldn't be a problem....many run 5-7 turns out..you may get exhaust overrun popping with 2.5 to 3...mine does..

Why not use a colortune kit

I've got one but I've not used it yet (bit difficult as you really need a dark garage)

Some people here talking about using one

If you try one let us know how it goes.

Thanks, just wanted to confirm what I read on the search.

Those were mentioned on another forum I frequent. Had a link to a video of one in use. Considered getting one, but not sure if I'd use it enough to justify...
Cool factor may win out, though...
