Hi mate
Just tried it without the plug leads on - still the same.
I am using 1300 powermax pistons which will increase the compression ratio (I know you all know this lol).
I found a thread on here with a guy with the same problem, which was cured by using a gear reduction starter from lynx ae for about £140+ vat.
I think this may be the way to go forward as there seems to be a theory that the crossflow starter cannot turn over an engine with high compression
very well.

If it was me (a shameless bodger) I'd take a plug or two out aiding in turnover speed and see if it starts up on two/three cylinders - (leave
the removed plugs grounded though) just to see if it starts.
I know mine will start on 2 quite happily.
Probably best to ignore me though

I have in the past started engines with one or more plugs removed as a last resort, in one case on a motorway slip road . If the engine starts you may
be able to refit the plugs with the engine running if you are careful , then use a pair of plug lead pliers to refit the leads. I have the same engine
mods but have never had any cranking problems although my car has a pre engaged starter which is more efficient than an inertia starter . If you do
fit a pre engaged be aware the ring gear has a different number of teeth.

Hi guys, i know this is a very old thread, sorry to dig it up, but i have the exact same problem with my 1360 xflow and this was top of the google
results when searching for a similar problem, turns over really fast without the plugs in but really slow, to the point of stopping and the starter
getting really hot, only difference is i have had it running, seems to me there is a very fine line where it will start, if we turn the dizzy very
slowly clockwise it will fire up, but once it's cut out, it needs to be turned back clockwise to speed up the starting.

Have you ever checked the ignition timing using a timing light? Somewhere around 8 to 10 degrees BTDC would be a fair starting point. Also what
distributor are you using? I've known Bosche to sieze the auto advance flyweights causing problems and the old Motorcraft were never very good .
A bespoke distributor to suit the modified engine would perhaps help?

i am using an accuspark dizzy, but i took it out anyway to see if it would turn over, anyway i just went out again, turned the key and it turned
slowly, so i kept the key turned and it got a bit faster then faster and faster until it was whizzing over at full speed, then it kept doing it then
each time, it was gradually slowing down i think due to the battery draining, but if i waited a few seconds it would whizz round again. i know this is
a daft question but the alternator belt couldnt be too tight could it???

I don't know the crossflow engine but check if the wires, connections, fuses, ground points etc are getting warm/hot during cranking also check
the connections are clean. If the wire is getting hot the resistance will be significant, the impedance of the motor will be tiny and the voltage
across it will drop significantly if the wires heat up. Put a multimeter across it if you have one.
