About contact points.

[AvB]

Hello folks!!

Today on the first try to start the engine i got an explosion coming out of the exhaust system. Fearing it was the Contact points i removed the distributor cup and the rotor to find that the contact points where in bad shape !!!, I've remove the old one and replace it with a new one, now everything appears to be OK.

My question is, how long as i have to change for a new contact point , is it for time or mileage ??

I've set the gap of the contact breaker points to 0.42mm. Is this correct? i have read somewhere that Haynes suggests from 0.37mm to 0.43mm, but Fiat recommends from 0.47mm to 0.55mm, both of them are correct?

Thanks

It's always worth checking the ignition timing after the contact points have been set up.

@Chris and @mile

Thanks for the info. Im using the Zelmot Distributor and the gap is 0.42MM , and also i did check the ignition timing, everything its working really smooth so far xD, hope it will continue that way!
