2000 Tc engine doesn't run

[mirafiori76]

I took the complete head from another engine which always fired immediately without moving, removing or adjusting the cams. They're alright. Thanks

Is the compression ratio ok?

[mirafiori76]

Yes, it's about 8.9

[131 Devon Dave]

May be fit a standard twin choke carb to see if it will fire with that?

[mirafiori76]

Like I said previously in this topic, I don't have one. Only the twins that came off the original head.

Im not being funny but it would be quicker to drop in antother TC engine if you dont get to the bottom of this problem.
That is if you have one spare.

[djape1977]

i don't think that it has something to do with engine not starting but it's one of electrical problems that's common on all old cars

106usj,

What good will it do to build in another engine? It's just the engine-block. It's the topside which gives me headaches.

Pedja,

I know of the electrical problems all too well. This car has none except for the ground cable getting hot.

it takes only a few simple things to make an engine run...
fuel.correct ratio.... you say its OK
spark ....you say its OK
air..... you say its OK
compression ....you say its OK
correct timing ...you say its OK

 so which one is not OK as it has to be one of these

 there is nothing else ??

My thoughts exactly. Everything is checked, adjusted, changed and changed, adjusted and checked again. This G.dd..n engine should fire. But it just won't.
Tomorrow I will spend another few hours on it, just to get some life from it. I'd rather spend he time with my Abarth or my second Abarth, but I want to get it running. After 5 years I really want to drive a 131 again.

[mirafiori76]

Here I am again, trying and trying over and over for 4 hours. Fitted brand new spark plugs, cables, ignition cap. Adjusted contacts in ignition (smaller gap).Started with choke on, choke off. Even unbolted the exhaust. Blasts from carbs and exhaust but no life in between.
I'm getting desperate here, doubting myself. Why won't this engine fire?

[djape1977]

did you change the electronic ignition unit (comutator or whatever it is called in your part of the world)?

[mirafiori76]

If you mean the part in the ignition unit with the white cable, i did.

Your fuel has lost it's sparkle. Get new fuel as the aromatic VOC's that give fuel it's sparkle have evaporated. The car has not run in four years you say yes ?

New fuel, bled it through all the way, give her a go and she should cough into life, and don't be surprised if the car needs new plugs again, as rotten old fuel destroys spark plugs, even brand new ones..

OK here we go again    
Its a constant problem -everything works but it doesnt start.
Blowback thru carbs and exhaust MUST mean its firing with the valves open-thats given.You have good compression -therefore the valves must be closing correctly or you would have little or no compression.
The only thing that can possibly be wrong is the ignition timing from the distributor.If say for instance the pulleys were wrong on the cams the valves would have smashed by now or would they - theres a thought.
Anyway if you cannot adjust the timing to get it to fire correctly the distributor must be wrong or the gear is wrong on the distributor i.e. the distributor is turning slower or faster than the engine.Do you have a strobe light to check the ignition timing is static when cranking over - just throwing more in the pot for you.Failing that lift the cap off mark a position for tdc and crank it over and see if the rotor is coming back to its normal position.You could do the same with the cams check the lobe position at tdc turn it over and see if there creeping from tdc wouldnt be the first time a 1 tooth less pulley was put on and caused things to turn slower than they should.
