have tried a load of fuel and redex, checked the timing yesterday as well, thats fine, its really predictable what it does, it starts absolutely on the button , revs a perfect 1100-1200, stays like that for a minute or two then starts hunting up and down , lower and lower until on the fourth decline it just cant pick up anymore. just fizzles out . wierd
ive got an isv coming now so im gona keep my fingers crossed that it will sort it
