Mine has a watery/waxy/oily looking stuff inside it . Hope this is kinda normal ? It's a wore out gas engine , but had good compression last time I checked it . THANKS !

They'll do that if you run them a lot of short trips, running for short periods of time doesn't let them get warm enough to cook out moisture.

Thanks Tom ! I have been tooling around in the back yard a good bit lately . Hope to stir some dirt very soon , that'll get the engine good and hot .
