Vintage Dirt Bike Q & A

Did a search but didn't find the answers I'm looking for.

Bringing the bike back to life. Installing a carb kit I got online. The inlet valve to the carb has a much bigger hole than the original I pulled out (K-2mm). I figure this is no big deal, the float bowl will just fill up faster?

I cleaned all the muck out and need to know what good benchmark settings are for the washer on the needle and the two air mix needles. The big one was out almost 3 turns and the little one out almost 4. Who knows what's correct as the guy before me was trying to push gas through clogged jets.

Any help appreciated.

Bob
