[Mini1275hle]

Hi

 

I have a Mini 1275 HLE clubman 1983. I have redone the head, new spark plugs almost everything one can think of to fix or replace on an engine. Have put it all together but it won't start and is shooting fire out the exhaust.

 

Anyone have any advice for me? Anything I might have over looked?

 

Any help would be much appreciated.

check that it is firing in the right order,  sounds like you may have it 180 deg out.  A starting point anyway.  Mine was like yours,  less the fire,  but popping and banging and it was 180 deg out on the dizzy

 

I think the firing order is 1 3 4 2 from memory.

Re-torque the head to make sure it is seated properly.

Once the head is re-torqued, adjust the valves.  This is a must-do step.

Since you have replaced the ignition parts, make sure you put them on in the correct order.

 

Recently there have been several threads about checking ignition timing and firing order.  Please search for a few of them as they will prove helpful.  I will paraphrase checking the firing order below.  If you need information on setting static timing post that request and I'll add it.

• Remove the spark plug from cylinder #1 (water pump end of engine).
• Turn the engine over by hand until you can see the timing marks line up (for a first start 5 to 8 degrees BTDC) and see the piston in cylinder #1 coming to the top.
• Remove the valve cover and grab the two rocker arms above cylinder #1.  Try to wiggle the rocker arms.  If they cannot be moved, turn the engine through one more complete turn until #1 piston is again at the top of its bore with the timing marks lined up and the rocker arms loose where you can wiggle them.  (Don't try doing this until AFTER you have adjusted the valves as I suggested above).
• With the engine sitting like this (again 5 to 8 degrees BTDC with the rocker arms for cylinder #1 loose) remove the distributor cap and look at where the rotor is pointing on the cap.
• The cap terminal where the rotor is pointing should have the wire that will connect to spark plug #1.  If not, make it so.
• The remaing plug wires go on the cap in the order 1-3-4-2 COUNTERCLOCKWISE around the distributor cap.  Move the plug wires if necessary so the firing order is correct.

If you have moved the distributor in the block during this engine work, it will be necessary to set the static timing.  That is a separate topic and rather than go into it here I will wait to hear if you have need of that information.

Check a few thing like are you getting a spark , are you getting fuel to the carb then to the cylinders (most likley you are if you have flames)

 

Check you have the HT leads in the correct order

What is static timing?

[Badboytunes]

Id say the ht leads are on the wrong way round if you have not removed the distributor..........

^^^ We get the message re your question

 

Static timing is where the engine is timed up without it running.

 

IE, No1 piston at the top of the compression stroke, both rocker arms are " rocking " and the rotor arm is on the No1 ht lead.

 

I believe that the rotor arm whould be at 1 o'clock when you look at distributor with the cap off.

The remaing plug wires go on the cap in the order 1-3-4-2 COUNTERCLOCKWISE around the distributor cap.  Move the plug wires if necessary so the firing order is correct.

COUNTERCLOCKWISE looking up into the internals of the cap, CLOCKWISE looking down onto the top of it!

As Yoda said (and is shown in the picture he posted) looking down onto the top of the installed distributor cap the wires are located 1-3-4-2 counterclockwise. 

 

Mini1275hle, static timing is as Badboytunes said, setting where the ignition spark will occur without the engine running. However, it is not at TDC as stated.  Typically static timing for almost any engine is set for 5 to 8 degrees before top dead center.  That is a spec that is usually good enough to get an engine started safely.  Once the engine has run long enough to reach operating temperature the dynamic timing (with a timing light) can be set.  Static timing is easily set with points ignition systems and most aftermarket electronic ignitions.  I don't beleive it is possible to static time a factory electronic ignition using the same technique so they are often set by eye with final timing set dynamically.

 

If you removed the distributor from the engine during the work you carried out, you will need to static time the engine.  Since this is unfamiliar to you, take a moment to download and read through the PDF document I have that discusses what it is and how to do it.  See the link below and download a copy of the "Static Timing [1] PDF".

Oops! Sorry!

Still it's important that we defined where you are looking from when you describe rotation , isn't it!

Great diagram Yoda
