Escort Misfiring


N3K

Recommended Posts

3 shattered piston rings. All the wrong size too. Someone did the dodgey before I got the car it seems. All is well, had some machined and fit. Also had a complete rebuild, bearings and shaved head and all.

 

However! Yes, however! The car won't turn over. Hahaha. The starter is too weak the roll the engine over. It was sweet with the compression about 50% but now it's right up there it's acting weak.

 

Tried new brushes and bearing, still nothing.

 

Best I go for another one, yea? I've purchased a second hand one for $70. Really hoping it works and is strong enough.

 

If not, I guess it's new for another $220ish.

 

Ugh!

Strange it started before and not now...

Have you remembered to connect the earths to the engine, and checked they have good clean contact area

And the positive as well to the starter for that matter

It's not surprising that the starter is no longer up to it on a new, tight motor... especially if you have the spark a bit too advanced.

I gave up on the factory starters and fitted a Road Runner gear reduction starter after upping my compression to 12.5:1 as the factory units were only lasting a few weeks. There is probably other good aftermarket starters available now (mine was a pre-crossflow Mk1 Cortina)

I've gone and bought a second hand starter from an old escort and I am really hoping it's going to work. It's being fitted today.

 

If it doesn't, I'm gonna fork out for a high torque. 

 

Really hoping it does though.

Solved!

Along with an engine rebuild (at my request) we established the INITIAL reason for misfire. The shaft assembly inside the distributor was loose, you could literally rattle it by hand. Welded it up, drilled it through and got a tight fit again. Also found a piece of plastic inside by the advance plates which could have been stopping them from opening.

A good tune up and she runs bloody SWEET!

Engine has been rebored, piston rings fit, shaved head, ported head and rebuild with new gasket, valves, bearings etc.

Also fit a new clutch as the dude before me put it in backwards lol? It had worn down so much the rings were literally about to break off.

Yea. Basically how it went is we went in to investigate the misfire and it was electrical. It was the dizzy.

 

But while there, tested the compression and it was so low so went further. Just turned into engine rebuild.

 

Now the dizzy wasn't replaced but fixed. The main stem had a bit of play and it shouldn't move at all. We welded it closed and drilled it back through as an experimental effort. Worked for 3 days before coming somewhat loose again, and all this mucking around has burnt out my new points.

 

... Way to fix it? Buy a new electric dizzy and coil to match.

 

Going in tomorrow. Fingers fkn crossed.

Installed. Running mint again.

 

Odd though, getting a weird delay when first accelerating sometimes. Only for a second, sometimes car might jump a little and not quite sure what it could be? Dirty carb?

 

Oh to add, it doesn't do it on full choke.. runs mint on full choke but sounds rank revving hard and guzzling fuel.. and not good for engine haha.
