2000 Tc engine doesn't run

[mirafiori76]

Already have. Checked it today again. Thanks

Have you tried a new Dizzy cap and rotor arm. I had one that although looked a strong spark when cranking it over with a plug on the end of a lead.  When all together did not have a good spark to start because there was a spark track inside the cap. When you looked in the cap it looked ok. Drove me nuts at the time.

I also had one that would not run with all 4 leads connected but would run with number 3 off every time I put number 3 on it would not start.

[mirafiori76]

Thanks, I checked that as well. But, i will do that again. Perhaps I missed something. However dizzy and cap were taken from the other engine which always fired immediately. But i will check again.

These things are set to drive you nuts. It doesnt matter how much experience you have there will be one problem that will come along and catch you out.

Have you tried cranking the engine over and at the same time stick 24 volts through it for a brief time? I wouldnt do it on a modern car with an ecu bused tro t an old 131 with basic electrics used to be ok. I t will make the starter spin faster and the spark stronger.

[mirafiori76]

I don't have the possibility to do so. I towed the car for three blocks with high speed to see if it would fire. So I didn't have to use the starter motor which could use a lot of volts. But didn't work.

If its getting air,fuel and spark it must be out of time
Did you try spraying easy start in to the air intake whilst cranking like i suggested before
if it kicks in to life its a fuel problem.
How do you know its getting fuel,are the plugs wet
Did you time the car on no 4 piston
did you swing the distributor whilst cranking to move the timing
did you time the distributor 180 degrees the other way.

[mirafiori76]

Yes, tried it all. Spark is fine, fuel is there (all pistons are very clean washed by the fuel). It hasn't "Kicked"in 4 years now except for 30 cm flames from the carbs and something the same from the exhaust.
Turned ignition 360 degrees, tried switching cables 1-4, 2-3. Exchanged every part, again and again. Checked earth of engine and ignition. Checked timing over and over. There is a complete cylinder head with all components taken from an engine that always would fire immediately. From the carbs al the way to the other side like exhaust and ignition. Nothing works.

hi
can you chek the starter if he is working in the correct side for the flywheel or he is working in  the  ronge side

[mirafiori76]

Thanks, but it's on the right side of the engine. No, I mean the left... Starter is perfect.

I still vote spark! If it's got fuel in the cylinders the only thing missing is something to light it up. Have you done a compression test?

[fiat131sport82]

1 - what cam lift and durration for in and ex cam?

2 - what (in degrees) is valve open and close event for in and ex cam.?

now what have you set up to?

i have simular problems with my father have trevi volumex and 50 mm delorto carburater with alquati cams and we time badly but i was just 15 so learning no bent valve was lucky

[mirafiori76]

Yes, I did. Two times. Look back at this topic to see what's already done. I need something small, out of the ordinary. It must be something that we (and especially me) overlook.

[mirafiori76]

Suljo m,

Because of bigger valves I have lift inlet 35 and outlet 40. That shouldn't be a problem. Bhp around 160 or so, together with the twin carburetors, adjustable cam rods, and exhaust.

[fiat131sport82]

sorry freind i have read all and i have work many fiat t cam, spark and fuel is waste if timing wrong.

if high compresion this may be blow out spark on compresion stroke need diferent plugs.

valve clearance for hi lift cams?

what cams are used i have specifcation for most cam at home  

i garantee i will find why it do not start in 30 mins if i see engine, i promise you this, really i need to do my checks with my tools   you just buy me plenty strong beer and meat when i fix!

where are you friend

what is adjustable cam rod
