hello everyone!
everyone in the forums has been very nice so far. i was wondering if maybe someone else has experiencec this problem. in cold weather, the motor sarts rough, the tach bounces arouns for a few seconds, and you have to hold the starter on for a few seconds until it smoothes out. immediately upon starting, lots of air in the fuel line, and it seems to run fine, but if you let it idle for say 5 minutes or so, it starts to idle real rough, bogging way down almost like its starving of fuel, but it never stalls. almost like its misfiring. if you rev it a few times and let it idle for not even another minute, she runs fine. it never happens again. until you shut it down,m and the motor gets cold enough. it only happens when the motor is really cold. thanks for the help

i forgot to mention...i have been over the fuel connections time and time again. the only thing i havent done yet was to replace the fuel filter, or check the shutoff valve oring, because i cant get it out.
thanks
