Pilot screw

Just rebuilt the CV carb on my 04 sporty. I'm hoping that she just needed a good cleaning from being in storage. Worth a try before I start messing with the jets. It's running a .42 intermediate jet and a 180 main jet. Where should I set the pilot jet screw for the first start and adjustment? Thanks!

A 42 is rather lean, IMHO. I'd be running a 45. Leave the 180 main.

You can run the 45 pilot, and start at 1 turn out.

I was having problems with it running lean. I'm running exhaust with no baffles and had it jetted in GA several years back. It ran great there, but I got to AZ and started having problems with it spitting back through the breather every 10-15 seconds.

It stayed in storage for a long time without being started so I'm hoping it just needs a good cleaning since the elevation between GA and AZ isn't that far off. If this doesn't work I'll give the 45 intermediate a try. Thanks!

That's really nice of you man. I was just going to order one off the web. I just took it for a test run and everything is good except it's still spitting at low throttle (cruising around 55 mph in 5th gear). Is this something that can be fixed with the pilot jet screw?

Yes. However, turn the AF screw out to 2.5 turns and see if it stops.
