Come here for some petrol engine help!
Ok, so came to start the Rado on Sunday morning, cranks like hell but won't start.
Just been out fiddling, got good spark and fuel to the cylinder.
Compression tested it and found that cylinder 1 & 2 have 165psi and 3 & 4 have 200psi.
Now this could well be worn valve seals but could equally be headgasket, however it shouldn't fail to start.
So anyone got any ideas as i'm stumped and the My Wonderful Better half is carless right now!
