Crossflow help

[Gordy124]

Can anyone recommend someone in the Glasgow area that has good knowledge of Crossflow timing.
Getting fuel, sparks but timing is way out and won't start.
Thanks.

You're talking about ignition timing?

Don't think Crossflow are particularly unusual. The optimum will depend on the engine spec but a typical engine ought to fire up at about 10 deg static advance.

Don't trust that the front pulley timing marks are accurate unless you have verified them mechanically.

You wouldn't normally have any vacuum or mechanical advance while cranking. If you have vac advance set up, you might want to disable that if you are having trouble starting in case you are getting enough vacuum while cranking to over-advance the ignition - too much advance will make any engine hard to start.

Remember the distributor runs anticlockwise.....does it fire when turning key then die when released? check ballast resistor...can you smell petrol, overfuelling?...are the valves opening, the cams can wear almost round if not treated properly...I've known the starter motor to turn the engine over fine, but takes too much current, starving the rest of the electrical system of power...Pretty simple engines, you'll kick yourself when you find the problem
