RE: Cold weather help please
if you quickly increase throttle to full and it shuts off, your low end may be too lean. if you quickly go to full throttle and it bogs then shuts off your low end may be too rich. Check that. Also if you slowely transition to full and its not running right you may need to tune your high end then check the low end. Hope that helps.
I forgot to mention, Also get a OS #8 Plug those work the best. Make sure your fuel line is good and make sure your fuel tank is not leaking.
