can anyone listen and agree or disagree,i think there is rattle ie; piston slap,big end
or I am I being paranoid setup rb 236, exhaust stub came off ran for about 2miles before realised

Try using a long screwdriver against the casing in various places and put your ear against the handle to see if you can localise it, kind of like a stethoscope

Not that it helps but mine sounds like that and I'm always worried there is something wrong, so far so good with a few thousand miles on the engine. Mind you engine's ok it's everything else that breaks.

I can hear what you're on about and it could be a number of things. Whether it is something that you should worry about or not is not known.

What flywheel are you running? There are a number of failure points on different flywheels and at least 2 types can fail in the manner of the steel magnet covers coming loose and catching on the stator laminates as it rotates. I'd be tempted to pop the flywheel off and look for reference marks of it rubbing.

Cheers for now.

I know what you mean rosscle but tbh I would not know what to listen for, probably smash me ear in with the vibrations

Vespanic, I think I may be going mad listening to a few rb's on YouTube they all sound a bit rough
