Running stock Jetting and no TEC w/RS-3

[doakster]

Right now i'm waiting on my FCR and running the stock jetting with a full RS-3 with no TEC. Any problems with running too lean? I am getting some popping/backfire on decel but not too bad. Fuel screw is 2 and 3/4 turns out and getting colder up here in Maine.

Sounds like it is running about right, it does need a larger pilot as evidenced by the 2+ turns of the fuel screw. Cold weather coming is going to need more fuel anyway. Change the pilot 1 size up.
