Boys project car won't start. Its a 1971 mini, he has set timing, but when it turns over it back fires.Could this be because it is 180 degrees out. Or is it somthing else. Also when checking valves which valve on the number four cyclinder is the inlet and which one is the outlet. The motor was running before he transplanted it to another car .

Check firing order is correct with rotation of rotor, valves line up with manifold, eg: ex last one.

Awesome thanks, he is out in the garage tinkering with the motor as I type this.

So he took a running engine out of one car and put it into another, didn't touch a thing and now it won't run !I don't think so, he has swapped something from one to the other. Tell us what he touched. Ex In In Ex Ex In In Ex.

I would guess the firing order is wrong, the timing way off, or dizzy in 180 degrees out.
All easy fixes, and I have done all of them myself!

If my memory is correct, the distributor is an off set dog drive so would be difficult to get 180 degrees out. Having said that, it does sound as if the ignition timing is too far advanced, or the leads are on the wrong way. Go back to basics! Fuel, spark and co ordination!

If it is 180 degrees out, just change the plug leads to suit to see if it will fire.
As I recall: with the rocker box off observe when both valves are closed on number one cylinder, make sure the rotor arm is pointing to number one cylinder. Go from there.

Also make certain you know what direction the rotor rotates in before you put the cap back on
