hello!!
the thing u r saying have many reasons
it will cause bcz ur air/fuel mixture is to rich causing more petrol to burn and deposited on plugs...does u get change in ur average/liter..check this
another reason may be ur incorrect timing order or some tappet setting...and the other will be that the oil is burning in engine.check that ur tail pipe is not giving too much white smoke....
this is what i know!!
Thanxxxx
