Hi Adam, we had terrible trouble with an older set of engines exactly the same as you every time it rained… you can reduce some of the misfiring by reducing the plug gap in wet weather but unfortunately water will often find its way in to the engine if it’s very wet and constantly raining. The oil will look white and milky when you drain it out so top tip is to always drain the engines as soon as you can after the race (next day at the latest) if it has been raining before the moisture corrodes the piston and barrel. If it comes out white then you will need to put new oil in and run the engine for about 10mins to hot and drain that oil out and throw away again, this will get rid of any moisture and remove any corrosion. Then new oil in again for your next race. Hope that helps, unfortunately it is a problem for us all and some engines are more prone to letting in water than others but if you reduce the plug gap then that should help the misfire, i’m not aware of any guarding or special waterproofing other than spray WD40 on the plug lead on every pitstop! perhaps some of the other more experienced teams might share their secrets regarding this one 🙂 Hope that helps..
