Hi guys. Just done a head gasket on a 98 1.2 punto. Tried to start it and it turns over then stops turning before trying to turn again. Any ideas?

Cam timing?

I've lost count the amount of times I've checked it. It was out to start off with but certainly isn't now

OK, by " Tried to start it and it turns over then stops turning before trying to turn again" what do you mean?
Does the engine try and spin, give a cough then start spinning again?
Are you sure the HT leads are in the right order?

Yeah it turns over then almost like its locking up before continuing to turn over again. Leads are all correct. Marked them up before taking apart

Have you tried turning it over on a bar to see if its going tight (possibly a bent valve or something)?

Turned it over by hand and doesn't go tight. You can feel the compression as you would normally. On the fiat lump they shouldn't hit anyway or I've never had one hit before when belts have gone

Fluid finding it's way into a cylinder and hydraulic locking?

Take plugs out and see if it spins freely, if yes then go back to timing.

I'll have to give it a try. Has anyone had a valve bend on one of these engines? £40 bargain you can't complain

What's the history ? Did you get it as a non runner

Got it as it had a misfire to start with but when collected it wouldn't start. Head gasket had blown between 1&2 cylinder so it had a lack of compression
