    You checked you plugs/leads/dizzy cap/rotor arm etc? Could also be a weak spark.

    Most did, kicked in a 6500rpm, but ween't a soft cut thing, you knew when you hit it cos the whole engine would just die for a second or two when you reached it!

    Re: rough running

    What I can see on there it may be the mixture needs adjusting,or the meriting unit is sticking top of air filter box

    Re: rough running

    its probably going lean at high revs, most likely culprit is warm up reg, the warm up reg actually adjusts the system pressure in the metering unit, a faulty reg can effect the mixture throughout the rev range but most noticeable higher up the rev range

    Re: rough running

    I'd check the mix/co first and work from there, when was last time fuel filter was changed ?

    Re: rough running

    Checked your fuel pressure ?, as you did something that affected the problem, it seems very likely to be related, maybe your old filter was a bit clogged, now it's not and you are getting better fuel supply it's even richer, but at least you can rule out the filter now.
    What exactly do you mean spitting in the exhaust ?, flames ?, noise ?, there should be no amount of fuel coming out of the exhaust to ignite and spit, why not make sure the engine is healthy first, and do a cylinder leakage test, a compression test is ok if you can't access a leakage test kit, but can hide many things that a leakage test will find, maybe the spit/noise etc is a burnt out exhaust valve.
    I'd seriously start at the basics first.

    Re: rough running

    The noise in the exhaust was a popping noise back firing sounded as though it was running on 5 cylinders
    The original fuel filter was new as a cut it open to see but was told to upgrade to a xr4 one which is twice the size
