Does bob up and down slighty,about 6mm.Have checked for air leeks on breather pipes e.c.t..Surely it should run with an air leak if you keep the revs up?



Also fuel doesn,t come out of the injectors even when flap is pushed down.I,ve tried every thing to get the fuel out of the injectors but no joy.If i had an air leek,wouldn,t fuel still come out of the injectors?
