ok this is somthing new to try i havnt done yet. I will look into this. Sometimes it seems to clear up and run great. Did it to me tonight. Then 5 mins later its pig rich again and giving me a headache the fumes are so bad. And yes i have the garage door open.
Most of the night tonight i had to keep foot on the gas or it would stall out.Seems to run a little different day to day but usually always rich and usually will idle fairly well.
