Finally got around to ordering the red Honda engine cover ,it was $16. saw a few cheaper ones but you had to be a new buyer on the site or another cheaper one had a minimum spend of $40.
The colour on my camera must be a little out because in the images the engine cover looks a bit pinkish but it's more a dark red.
I hadn't started the Honda trimmer for months and it started 3rd go on the starter with old fuel in the tank so it's still running well.
One article I was reading the other day said to only use fuel that is one month old as they said at that time it's already degrading , they were talking about fuel with mower usage a little extreme to replace your fuel every month.
Then again fuel in an unsealed mower tank that is exposed to air can degrade quicker ,in a sealed container, fuel can last a few months.
98 RON high-octane, premium fuel is all I use , the 98 if it does get left in the carby long term it's more prone to gum up the carby than when using 91 which corrodes the inside more.
