Unsure about the pinch test..

So you pinch the fuel line as close as possible before the golden metal entry into the carburetor right?

How many seconds should it run? Some people say 3 seconds, some say 4....I'm really unsure.

It's an approximate number, nothing to be too critical over. Go by the 3 second rule. If it's over 3 seconds then it's rich and if it's under 3 seconds its on the lean side but as long as it is close to 3 your good. You don't want it to die after like one second or stay running for like 5 seconds or more, just count to 3 in your head and if it is close your good. You should really tune by performance and smoke anyway, the 3 second rule is just an easy quick way to get an idea of where your setting is.

BTW I pinch mine a couple inches away from the HSN inlet. I don't think it matters as the suction from the line is completely cut off, it only burns what is left in the carb. Hope this help you out.

I was a little confused about the concept of the pinch test until you mentioned suction from the line so the fuel is completely cut off. I never even thought of that.. Thanks alot!
