Ah, you just got struck with one of those "sometimes xxit happens" type of things! Usually it's something weird and wacky that you would never imagine happening that completely ruins your day, like this! With the filter heads a tip is clean everything well with carb cleaner to remove any oil and then use a bead of shoe goo then zip tie it. You can peal off the shoe goo if you ever take it apart down the road unlike glue or CA.

No worries I understand. I was just pointing out that it was not really the motors fault because people read stuff like that on the internet and then jump to conclusions that we must be selling bad stuff or something. You know how stories change when passed from one mouth to another lol. First it starts off with my filter fell off and I needed to replace some stuff and then it turns into I read about a guy that had one of those engines and he had to change the piston and sleeve and all of the bearings just to make it run right lol!

If you see scoring on the p/s then that means that some pretty large pieces of dirt made it through the engine, so it was probably necessary to replace the stuff that you did!
