I’ve been changing oil by myself for years and it’s difficult. Trying not to remove lower cowling using plastic funnels and hoses leading out of the lower cowling was difficult. I have a new method remove the louvre on the cowling on the pilot side. It is directly below the quick oil change valve (8 screws) small aluminum funnel with drilled hole to hang on quick valve about 2’ of garden hose straight to 5 gallon pail. I hope this helps very fast, clean and easy.
