Hmmmm ok just did 45mins or so chipping away at the 3500m2 of surging Kikuyu....alas the BPR5ES doesn't seem to have changed much, still getting puffs of black smoke when I hit a thicker patch of grass. I'll yank the plug when I go back out but I suspect it'll already have a good deal of carbon on it.
I'm suspecting it's either the carb settings or perhaps something odd has happened with the oil blend and its caused problems - when everything I mixed did have a working/hot weight of 30 or above - but it seemed surprisingly thin when I took checked the level before starting. Alas due to my diligent mixing I have around 6L of it.
I might buy a litre of bog standard 10W-30 and see if that still has the issues - if nothing else I'll eliminate it as the problem.
Any other ideas welcomed - dunno if I should try and adjust the carb now or if moving too many variables at once just confuses isolating the problem?
