Poulan 46cc cranks are made by Husky, I very much doubt the threads are 5/16-24...Close, no cigar. 8mm, just like all smaller Sachs and Husky, and all other foreign engines...Large Sachs and Husky are 10mm...
Quadra threads are US, 5/16 and 3/8-24
Zenoah threads are 8mm and 10mm
Stihl are 8 and 10mm
DA and 3W, 8mm
