What simple OHC cam engine is this in the last pictures? Do you know the brand ? Looks exactly like mine which is a 139cc, but I can´t find the brand (for replacement parts) and valve specs.
Thanks !

I set The LASH at .004. I think it calls for .005. Do I need to change it to .005? It is a 2015 Husqvarna lawn tractor.
