Hi
I get the cam timing marks,very clear but on crank is it the top.of the gradient or bottom?
Pics are from previous posts but still I am confused. 1989 panda 1000cc fire engine.

I haven't done one of these earlier engines for some time but I've always set them to the top of the ramp ie. as shown in the picture you posted. So probably about 10 o'clock. Meaning that if you were to start with the timing mark on the sprocket/pulley/whatever you want to call it, at 9 o'clock and turn it clockwise you'd come to where it's shown in the picture. If you turned it further you'd be going down the ramp. I'm pretty sure this position, ie. top of the ramp, corresponds to TDC.

Does that help? please ask again if this doesn't help.

Thanks. Wish i had the timing plate inside the bell housing but not with it !

It does yes

That was a 1996 Autodata Timing Belt book I bought recently to add to my collection of manuals.
When I die my children will bin the lot;)
I've seen several "interpretations" of how the crank should be lined up on these earlier engines. Always lined up Felicity Fiat's like this (the Panda in my Avatar pic) and she ran splendidly.

I've got a whole cupboard full of manuals, like you, acquired through the years. Non of my kids have any interest at all but my youngest brother's son works for Jaguar land Rover - He's one of the guys who goes out to sort problems (mostly to do with electronics/softwear he tells me) and he's to get first refusal on the entire contents of my garage. After that I'd like the son of the owner of a smashing wee garage very near me to take his pick (he's starting to take over from his Dad who will be retiring soon) and after that Mrs J says she's going to put the word round all the wee garages where she knows I'm known. The rest can just go in a skip she says. Sounds like she's actually been thinking about this? Is she expecting me to "clock out" soon?

Definitely misfiring, any chance a valve was clipped if cam belt was done .
I know book says damage unlikely but doesn't say never.
Have you given it a compression test?
Just a thought are the plug leads on wrong or is the distributor cracked/shorting.
Another test if you don't have a weak heart is to remove plug leads one at a time to find which one isn't working.
I have done this many times , but also have had an electric shock many times also;)

definitely compression test.

Taking a plug lead off with the engine running to find a misfire used to be a common thing didn't it Mike. Then it became a difficult thing to do when "plug on" coils became the norm. I'd be a bit wary about open circuiting an HT lead with electronic ignition though? Might get a back emf which would blow some components? You could always short it with the lead still connected and get the same result.

When I was at college the "amusing" thing to do was to pull one of the HT leads from one of the stand mounted test engines while it was running and hold it behind your back so noone would see. Then, as someone walked past you'd say something like "Oh, what's that on your nose" and with index finger extended, point at his nose. If you could get close enough a spark would jump off your finger onto the unfortunate's nose which gave him a shock and caused generally great merriment amongst all who saw it. Of course you had to be wearing thick soled rubber shoes otherwise all that happened was you ended up with a hell of a sore arm from the muscles twitching as you held on to the plug lead - guess how I know!

Gonna change coil and leads etc.
Yes compression test too. Will. Check valves
