also van keeps cutting out but re-starts ok, however with strong smell of fuel. seem to have hi rev on tick over too.

mechanically im crap,

although thought it may be something to do with the carbs

a bit of info would help, petrol obviously but a/c, w/c, 1.9, 2.1 ? hard to advise without knowing this

high revs sounds like air leak in manifold area, check the nuts that hold the carb on if one is loose it will seep air in. backfiring maybe ignition timing, "pooh" points,plugs,leads etc

there is something amiss with fuel/air mixture. finding it is a proccess of elimination. think carb

could it be a case of blocked jets on the carbs.

has been suggested before, if so what do i do....
