[misfire when hot]

thanks folks. Already changed: leads, points, spark plugs, coil, wrapped up fuel pipe to see if over heating was the issue. If it is heat related could it be sticking valve or valve related? I have tried pulling off lead from rear spark plug and it seems not to make any difference to running sound when stationary. thanks, Leigh

[misfire when hot]

Hi, after about 1.5 miles(when hot) my 1966 2a begins to misfire and continues to do so, although will still reach 50 mph ok. I've changed various parts, condenser, checked timing, changed fuel lift pump, changed coil. I've not done compression check. Timing done with strobe. Sounds fine when cool. Choke does not seem to make any difference to the misfire. Any thoughts, many thanks, Leigh

[2a coil connections]

Obviously the large (King) lead goes between the distributor cap centre terminal and the centre coil terminal.

Have a look at the terminal end of the coil - you will probably see one terminal marked + and the other -

As your vehicle is negative earth connect the - terminal to the lead going to the distributor contact breaker connection as this leads to earth - and the other to the positive supply from the ignition switch.

Noted. I didn't do a very good job at explaining that I have 4 leads including the HT lead. The vehicle may have been positive but it now has an alternator and battery terminals looks normal so that makes it a good bet it is negative earth.

- The HT goes to the middle of the coil, that leaves three

- I've got a lead from the ignition side - does that go to the + or neg

- I've got a low tension thin lead coming out of the distributor - does that go to the + or neg

- and tricky one...I've got an old brown fabric one coming out of the loom - do I need that and if so where should it go?

AND what happens if I get it wrong?

I'm resisting temptation to find out!!!!

Many thanks for any help. Leigh

[correct wiring to the coil can u help.]

Hi, I have a 2a 2.25 1964negative earth but not sure where the old brown wire, LT wire and ignition wire should connect to i.e. positive/negative on coil - any help would be much appreciated. Leigh.

[2a coil connections]

Hi, help. I have a 1964 2a 88 converted to alternator negative earth Landie. I'm having misfires only when warm/hot (2 miles+). Also problem restarting if hot. Thought it was fuel or a dozen other things however saw a post somewhere which suggested might be connections to coil are wrong way round so starts OK but then develops symptoms I am experiencing. Changed coil recently but it might well be I have got connections wrong. Where do my three wires go please?

a) LT lead from distributor? B) wire to switch c) old brown wire going back into the loom? Thanks for info on wire destinations.
