Hi, first of all I must apologize becasue I am very new to this. I am trying to restart my grandpa's old chrysler motor. It is a 3.6 hp Model #-32HA Serial #-7549. I don't know anything about the year. I believe i should use 24:1 mix ratio. What kind of oil do I mix with? If anyone knows what the 2 knobs on the front are for let me know. One has a C on it and I am assuming it is the choke. But the other has a F on it and I dont have a clue. I haven't even put fuel in it yet becasue I dont want to screw anything up, but I need to try and get it working for a trip tomorrow so any advice would be great! Thanks in advance, Garrett.<br />garrettcrane@hotmail.com
