I'm getting ready to sort my SIB out for the winter and will be doing that this weekend. With regards to the engine (Yam 30DMO), I'm going to be spraying the carbs and cylinders with fogging oil but I'm also considering changing the impeller, fuel filter and spark plugs so I know that it will not need anything when I use it next year. But it's only done 10 hours (not even that to be honest!) since it last had a service so should I change the impeller etc? Also, I need to adjust the carbs so that it idles properly (it keeps dying when taken below the start position on the tiller), should I also do this before storing or next year? Cheers in advance!
