So....ive had leaking valve stem seals for a few years now (puff of smoke on start up then clears). She does use some oil but runs really well with 130 PSI in each pot.
Starts well from cold and when it's been left for 10 - 50mins. However anything after 15 mins and it takes an age to catch. Ive read all about the fuel evaporating etc but I'm also thinking it's maybe the fuel pump with a faulty valve? Fuel running back through the fuel bowl?
Or...oil getting onto the plugs which eventually clears and catches?
I don't want to pull the head but depends on you knowledgable folk
Thanks
