C 161 Gas Cap cracked

[Exhaust 25]

I’ve got a C 161 that I am working on, its new to me, I’ll post pictures when I get some.  The engine was surging at upper rpm, I filled the tank full with RV fuel 90 and the surging is gone!  Unfortunately I was tampering with the carburetor for other reasons (bad gasket, leaking fuel, and trying to resolve engine surge) and now the engine is running poorly it needs half choke.  That’s another matter that I’ll work on.  But my real question is I wanted to replace the gas tank cap, do any of you know a good source for caps or should I just go to a small engine shop looking for a substitute off the shelf?

 

Its a k341a with the plastic tank under the seat.  The current cap has a large crack in the rubber seal.  It’s the one with a float mechanism that no longer works.  

 

Thank you!

Lowes sell a nice cap. I have gave up on the ones with the dial. That plastic cap on the dial pops off and then water can enter.
