Mr 914-6 and I discussed this a bit on the Pelican board and I thought I would throw it on here too.
When I start my 70 "S" when it is cold outside (40 degrees or less) t run extremely rich. It chugs like a top fuel car and loads the plugs. Car runs very clean when it is warm but is excessivly rich when cold. Is there any way to adjust the amount of choke on that bimetal thermostat? Thanks
