I was adjusting my 1984 mayfair's valves and I think the timing is now off.

After setting everything I reinstalled all the spark plugs and leads and now the car won't start.

It turns over well so I'd suspect that the ignition timing is now completely off. I know briefly how to adjust the timing when it is minimal, but how would I go about adjusting the timing for when it might be a full rotation or so out?

Is there anything else it could be?

Make sure the leads are in the correct orientation.

Plug leads on in the wrong order? I'm unclear as to why you took them off to check the valve clearances.

Damn sight easier to turn the engine over to set the valve clearances with the plugs out.
I'm unclear as to why you wouldn't.

Thanks for the suggestion. I've had a look just incase I made a silly mistake but they're all in the right order. Same as before when it was working. I don't suppose there could be anything else? Is there a way to set ignition timing almost full rotations at a time?

Before you start to chase the timing, might be worth checking the 3 basics (Fuel, Compression, Spark) in case you have missed something when putting it all back together.

Setting the valves would not affect the timing unless you had the timing chain removed.If it ran before you started check everything you have done assuming you have done everything wrong is the best approach for me.If it has never run use a manual to correctly set up the timing.Good luck,Steve

What are the valve clearances set to? Make sure the rocker lock nuts are tight enough. Check all the electrical connections at the front of the engine

Will do, thank you

Yeah I thought that it shouldn't affect the timing but I couldn't conclude anything else. I'll resort back to Haynes. Thank you
