I am currently working on my grandma's walk-behind Lawn-Boy Commercial Duty model 222-41. I have run into some problems while working on the carburetor. I have replaced the main jet but the problem is the main jet F- part #94-5710, which screws into the main jet. This part has been out of prodution for a number of years, I have checked with several shops and there is no substitute availble/produced. I have also looked on eBay without any luck.
Any suggestions on what I should do?
