try some engine start see if it will fire. maybe the damp conditions or manifold taking spark away. condenser/points, check all those things. Back to basics.

Did it fire at all? If fuel is getting into the inlet manifold, the problem is probably electric. Can you pull a plug and check for a spark?

no didnt fire. tried to remove spark plug, but because of the angle working behind manifold broke plug. now have to travel 60 ks to get new plug to see if spark is getting there. probably have to remove manifold to re fit.so will have install newgaskets .grtting a expensive exercise.

The benefits of a coil and dizzy are not to be disregarded . you dont really need the plug to see if its getting spark just pull the rubber back off the lead and hold it close to the block, or jam a screw driver into the lead and hold it close to the block. I had a 355 that was hi comp it used to kill starter motors and batteries used to struggle to turn it over . but put your foot to the floor and it would twist the chasiss. lol

Not sure about the type of ignition you have, it sounds like spark, is there either a ballast resister or a condensor in the system,

I couldn't get mine to start once on land, cranked over fine, checked fuel getting to carb, tried start ya bastard spray etc, but nobody home, so gave up. Let batteries charge up overnight, and tried again next day, still nothing, and couldn't see any spark, it was only then that i noticed that the lanyard safety switch was off, felt a right old plonker. But if you have spark i guess that's not your problem.

is the starter taking the power away from the electronic ignition. If it goes below a certain level it wont supply spark.

starter fairly new. on two batteries turns over quick. if module was crook would there be spark ,but not strong enough to fire.
