Technical Timing enquiry fiat panda classic fire engine

[Good104]

Hi
When timing is the firing order 1342 from cambel pulley end or dizzy end
Reason why is my engine will only fire up if I go from the dislzzy end 1342, opposite of Haynes
1000cc carb fire engine, same as. Panda and uno
1989
Although clearly on cylinder head is the cylinder numbers I know.
Please hp
Cheers

Any good?

Exactly what I have done and still don't fire up.
Crank and cam timing marks done as per manual.
Only fires up if I do opposite so must have something out, good spark on all. Plugs and new distributor too

I had a HYnes Manual for a renault 12. It was wrong. Acar worked when I aligned valves from fist priciples. TIMING MARKS were wronly shown 180 degrees out. Dont necessaily trust them.

Can't comment about Haynes Manuals, but my manual is the expensive motor trade AutoData version of that era, that the motor trade relied on, so I would expect it to be correct.
I would go back to very basics and find number one cylinder TDC on compression stroke, connect correct plug lead to that with points just opening, then turn engine in correct direction to next cylinder on compression stroke whilst watching rotor arm direction and put that plug lead on that cylinder and so on.
When at college as an apprentice they got us to time an engine, valve and ignition with no timing marks at all and get it running. It showed we understood the basics.
Obviously what we had to do was much harder as we had to time the camshaft as well, then fit the timing chain. I appreciate engines are more sophisticated these days, that was in 1969 but the principles are the same.

I will, must be the ignition, I have put a electronic distributor on so will check that too.
Really strong spark, just at wrong times?
Appreciate all your help, been a saga this one for over a year now.

I am still a fan of conventional points ignition as less expensive to fix when it goes wrong and usually possible at the side of the road, so no need for an expensive recovery job!
