Hello all, managed to get through loads of stuff without asking recently, but here i go again, this one is crossflow based, as opposed to jeep stuff, but i know one or more of you will know.
My jeep has a 1600cc crossflow, hadn't run for ten years, i had it turning over and coughing very shortly after it got here, now the jeep is complete in terms of floor and body and electrics and stuff, i want to get it running well, i fitted another dizzy as mine was rotten, and i have a fantastic spark at the plugs, bit of trouble convincing the fuel pump to pump, but that was because the fuel pipe was like a sieve, so i have fuel and spark, and amazing back fires, absolute beauties, 200 decibel pops and flames 10' long, the neighbours hate me, but i have managed to scare away the crows that have congregated around our house recently!!.
I am thinking that the spark is arriving at the plug shortly after the exhaust valve has let the un burnt fuel escape down the pipe, then igniting it somewhere near my left leg, simple question, can someone talk me through simple ignition timing, haynes are great but i can't see these timing marks they talk about, i know that on compression stroke on number one cylinder my rotor arm is heading nicely towards my number one lead, but something is wrong somewhere, probably stupid simple, any ideas??????????

Hi, don't you just love God's own engine. I do.
I don't hold with all this timing mark stuff either, they're just there to get you on the right track. If as you surmise, the spark is arriving late, just advance it by turning the distributor in a clockwise direction. When you've reached a point at which the engine will start and run, let it idle to warm up.
Then, with the engine running at a fast idle, turn the distributor clockwise until it runs fastest. Then back it off slightly anti-clockwise so that the speed just starts to drop. secure the distributor, reset the idling and go for a well-earned drive. When you come back, let the engine cool down and try to start it again. If it does OK, you're lucky because the job's done. If it misfires and kicks back, the timing is still too advanced so back off the distributor (anti-clockwise) a touch. Do this until it will start without kicking back.
If someone tells you they can do better with a timing light, let them try and when they've c@cked it up, ie it runs worse, do the above again.
This advice is offered- it is not warranted to work and you follow it at entirely your own risk. Do NOT try it with a Pinto engine as they have much closer tolerances and for some reason will time more accurately with a timing light than doing it manually.
If you're worried about touching the distributor with the sparks sparking, wear thick gloves and stand on a spare tyre (one without its wheel).
Good luck

Good job i am stupid!!!!!!!!!!!! 180 degrees out, thats all, explains the firework display night before last, came home from work, read the reply i got, thought about it for a while, had some tea, went and looked, whipped the rocker cover off to see which valves rocked when number one piston came up tdc, found the timing marks, put the leads on the correct way, taped up the split fuel pipe!!, taped up the split vacuum advance pipe, plumbed my lashed up gallon can complete with two stroke mix!!!!!!!!!!!, pumped the throttle, attached the wifes galaxy via jump leads, turned the key, and what a sound, one 1600cc crossflow without exhaust running like a dream(one of those dreams you hope you wake up from!) so, tomrrow i will refine the timing, let it have some proper fuel(bit smokey on two stroke!) and DRIVE IT UP THE ROAD
