Hmm. KR lump is intrusive, what does that mean mate?

Im thinking i maye have kicked myself in the foot here and should have timed her properly. Damn.

With regards to the crank timing, is the mark on the round pulley, or the little cog behind it, because i had that pully off and there were no notches

cheers so far guys

Use the flwheel tdc mark for crank timing. You have to remove green gearbox bung completely to see it. Confirm it with something long shafted down cyl 1

Intrusive means that your engine, WILL bend the valves if the cambelt snaps, of is fitted incorectly, as opposed to a "valve safe"
engine, where there is sufficient clearance between the valves and the pistons, making contact, regardless of the state of the engine impossible

Hmm i guessed as much.
When it comes to turning by hand then to check the marks, how can i turn it without damaging the valves in order to time her properly? Because if shes out now, she need turning around to get her straight again?
cheers

Use the 19mm multi point bolt on crank pulley to turn bottom end, and the bolt on cam pulley to turn top end. If they're well out, you'll need to turn each one a bit att a time until they're not fouling and in sync.How can you do a h/g and not know this?

Right, I suggest you remover your cam cover and remove all spark plugs and insert a long screwdriver (through the plug hole) into piston 1 (closest to cam belt) and turn either clockwise or anti (with a breaker bar on the crank pully) until she is at the top of her stroke (when the screwdiver is pretruding most). Then see what the hell your cam is doing in position 1 (all 4 valves should be closed but it sounds like this isnt the case at all). If you are lucky and the valves are closed make sure they are also all shut at the valve set for cylinder 3 too. Do this today and tell us your findings, then we can progress in a positive manner.

Oh and for the record, your cousin is a moron of the highest grade.

Sorry, I thought he was talking you through doing the job, not just with you whilst trying to crank her over apres job. Resume normal service  :embarassed:

Right guys, ive learned a lot about timing now!
I took the cam belt off, turned the cams to TDC, checked the marks on the cam sprocket and the dots on the cams to confirm this.
Then turned the crank to TDC and checked with a screwdriver AND the TDC punch mark on the flywheel to confirm this.
Put the belt on and the flywheel mark moved out of view, so reset it and tried again, this time the flywheel mark is in view but out by about half a centimetre, but IIRC it needs to be a few degrees out anyway, 6 i think?
To be safe i turned her by hand with the belt on and she done a full revolution with no problems, no crunching or anything, she went around fine.
Tried to start her, and she still wont budge.
Any ideas?

You need to set the pulleys to tdc bang on, top and bottom.. Its the dizzy you set to 6deg's btdc, with a strobe light, timing the ign up to the big diamond mark. The small dot punch is your lower tdc mark to line up with the point on the gearbox casing.
