Hawk - Stock Carb

Fame28 · 04-26-2016, 02:30 PM

I have swapped the carb on my Hawk as well, but I am having excessive idle issues when cold vs. when hot. If I tune the bike to idle properly while running hot it won't start while cold even with the choke on without giving it gas or having to readjust the idle air screw on the side. I have the standard recommendation jets 30/115 in the bike. I adjusted the fuel mixture screw in the front a bit and it has helped, but I noticed my rpm's take an excessively long time for them to drop. I'm betting I have an air leak, so I'm gonna pick up a bernzomatic to check for leaks, but if anyone has any other ideas why mine behaves so erratically, please let me know.

That screw in the front of the carb is an absolute son out of wedlock to adjust.
