I fired up a poulan 42 today on gas/glow. Using a carb that I think came off a Poulan 46. It's a WT 285. Site says it is 13.49mm. All I have is 15% nitro/18% oil total synthetic. Used that and mixed according to earlier advice here. Tried a couple props. A MA Classic 18x8. Turned 8000. Then went to a APC20x10W. Turned 6650 to 6700. Going into a CMP Katana 140. Already balanced out fine. I think once I figure out the best starting procedure it will work out fine. Hand started and used a starter both. Transition is good and idle is smooth all the way down to 1700. This is showing some real promise. Hats off to you guys that worked on this!!!!!!!!
