| I dont recall accurately but from memory (check the manual) the marks should be away from each other. I may be wrong but that would obviously give you the wrong cam timing and possibly low compression. CHECK THE MANUAL !!!! :) |

the manual does indeed say marks facing away form each other.
does it spin over really quick? have you got a compression tester? |

| changed the cams so they are facing away from each other as the manual and the timing marks at top dead center as it says in the book.and it still wont start my mate seams to think it could be the head and the cams shims need to be reground because ive put a new head gasket on my cam shims are 2.5mm on the inlet and 3mm om the exhaust. as it is leaving the exhaust open how true is this. |

check the valve clearences then, the values needed are in the manual.
do you have a compression tester and does it turn over very quick? |

cam sprocket marks should face away from each other
spark plugs are 2 and 3 from one coil, 1 and 4 from the other, make sure your plugs are good, they foul easily and will spark outsid the engine but not in. |
sooo.. who wants to lend me 6k then ? |

| put the cams in so they are facing away from each other.made sure the coils are the right way round. but it still wont start all it does is back fire out off barrels 3+4 throught the carbs. this weekend i will do a compression test on all the barrels.so i will let you all know the results |

| timing is slightly out by the sounds of that or swap plug leads round but it shouldnt fire back through inlets |
