I pulled off my brass caps to check and clean the pilot screws and passages this weekend. When i counted the turns, they all fell between 2.5 to 3 turns except for #1, which was 1 1/8. Is this normal? I did nick the top of the screw with the drill bit when i was boring out the cap. The screw still functions fine (i didn't damage the slot for the screwdriver). But i find it hard to believe that the drill bit would have turned the screw that much if at all.
By the way, just a few added tips that helped me: after nicking the #1 screw, I used a appropriately sized wrench socket on the others to stop the bit just short breaking through the cap. Then after much struggling with the wood screw and pliers, which didn't get me anywhere when trying to remove the caps, i used a 7mm socket and a drywall screw cut to an appropriate length. I inserted the screw through the socket and threaded it into the cap. A couple of turns with the screwdriver and it popped right out.
So now i have the carbs put back together after cleaning a second time, and new float valves and gaskets. Presynced with the bread tie. If i have time this week i'm going to put the carb boots back (and use a little hi temp rtv with the gaskets), and then install the carbs. I'll try syncing with a homemade pressure balance device. But that pilot screw has me nervous. I'm going to read Ken Talbot's auditory technique in the tech tips, but i'll probably have questions.
I'm missing the snorkle on my airbox. By the looks of the burn on the bottom of the seat, i think a previous owner destroyed it in a backfire. Is the absence of a snorkle going to hurt me (i mean performance-wise, not burning-ass-wise) as long as nothing is blocking the hole where it's supposed to be?
