OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Briggs & Stratton Engines B and S Sprint 375 or 450 series Carb screw size and type ?

That sorta like 1/8 pipe threads. Sae and British are very close but still not right. 1/8 BSPT is smaller Diameter and 28 tpi where SAE 1/8 NPT is slightly larger OD and is 27 tpi.

I would had never know the difference if it was a Kawasaki oil sensor problem.

That is why I went out a pulled the screws here and sized them with the tap and dies. But I wish companies would put the thread size in the parts lists too.
