Ive got a non-starting situation that's got me stumped.

I pulled the left rocker cvr on the Statesman (standard WB, on petrol) this morning, disconnected the HT lead at the coil while cranking the engine over to see what was happening at the rockers.

Put it all back together, took a while to locate the rear rocker cvr bolt and so had knocked the coil a bit with my arm... but nothing drastic.

Anyway, put it all back together and no go - despite nearly flattening the battery and booster battery pack, and leaving it for a couple of hours in case I'd flooded it. Starter motor turns the engine over, there's fuel spraying into the carby and I am getting a fat spark from the coil lead when earthed at the dizzy end and also at no.1 spark plug when pulled out and earthed.

The dizzy is not bolted down tight (haven't found a spanner that'll fit in there yet, though did manage to tighten it a little) so I thought I may have knocked it somehow (don't really see how, though) and so I turned it a little each way to see if that had an effect (will have to set it properly now, I know). No difference - the engine is not giving a hint of firing.

Despite the lifter noise yesterday the car was otherwise running fine; no hint of the non-starting problem, although I've noticed I have to pump more fuel when cranking from cold than when I bought the car.

The Max Ellery workshop manual I have for the VK (which I think is the same blue 308? Ignition description seems same as WB) says that if you have pulled the HT lead and turn-over the engine as I did you stand a good chance of damaging the module. Bugger.

I've checked the dizzy cap and rotor (the coil lead attachment on the dizzy looked a little chalky with corrosion, nothing bad but cleaned it up anyway) and all the HT leads; I thought the connector at the coil end of the lead may have swivelled around in the insulating end cap and so not attached properly at the coil but it made no difference when I secured it properly.

The coil looks fine as far as I can tell - the spade terminals appear fine, no oil leaking out of it or cracks.

I will go though the step-by-step test procedure in the Ellery manual tomorrow, and if that doesn't shed any light I'll just go stump up the $95 for a new module. I am hoping I won't need to do that.

Is there something I'm missing here?

no point in buying a module if youve got fat spark at a plug because it meens the module is working to send the spark..

this may sound silly but just coz you are getting a spray at the carby doesnt necassarily meen you are getting enough..

disconnect the fuel line between the fuel pump and carb and crank it over n see how much fuel is coming from the pump.it should be a fair bit not a little dribble..

I reckon its flooded,let it dry out ,disconnect the fuel line to the carb,get a can of "start you barsted"(true name!)and hit it!if you got any spark ,that will do something.trust me.it sounds funny but do it an see...jim
P.S FUEL + SPARK + AIR ***ALWAYS MAKES FIRE!

Yeah did that for ages, didnt work, although Im starting to think flooding may be the problem.

I havent worked on a carby car for ages but have flooded em plenty of times over the years and this isnt responding to the starting procedures I used to try.

Thanks for the ideas, Ill give em a go tomorrow.

Hi Phil.

Im sure the engine is just flooded.

Try pumping the accelerator twice, then cranking a few times with the choke fully closed & then hold the choke & accelerator wide & then crank again for a while.

You have good spark & you can see petrol spray down the primary barrels, so there isnt much left.

Often when working on engine it is easy to bump the accelerator lever many times, each time squirting petrol down the carb.

You mention that you may have moved the dissy. If thats the case move it a bit more anti-clockwise just to get it started, it can always be correctly re-timed later. More advance makes for easier starting.

Dr Terry.

Hi If all else fails try fileing or replacing your sparkplugs, It is not so common now, but back a few years ago some severly flooded engines sparkplugs could end up with a clear varnish like deposit on them that tracked the spark to earth via the surface of the porcelain and not accross the air gap. I think it must have been some fuel additive. Cheers Oily

Take out no.1 spark plug and see if its wet or black. if so replace your plugs.should fix the problem.

Just tried again this morning, same result as yesterday. No go, no hint of firing. Still getting a nice fat spark off the coil lead, it seems to be getting plenty of fuel.

Plugs are new NGKs, but noticed no.1 was wet when I pulled it out yesterday. Will try plug clean next.

Okay, now for a dumb question. If the dizzy rotor button is pointing towards no.1 firing point on the cap, it is firing no.1, right? I know the way I should verify is to see if no.1 piston is on the compression stroke, but when checking timing a couple days ago, I couldnt locate the pulley mark with the timing light. Checked just now and I think the timing mark is 180 degrees out (ie pointing towards the ground towards the passenger side) with rotor button pointing at no.1 cylinder. It is a big line of white paint someones put there, but I think I can feel an intent in the pulley also.

I havent pulled out the dizzy at any stage.

Whilst spinning the engine over see if your getting spark on your sparkplug leads?if not rotor,cap or leads,when you say your getting spark most people(me too)think its at the sparkplug end.coil spark means the module and coil is fine,check this by taking one lead off and spin the engine if it sparks ,change your plugs, if it doesnt change rotor,cap n leads.dissy
position should be fine ,you said it was running fine before??

also 1 more thing...check the rotor button turns when you spin the engine,ive had a timing chain snap and also a distributor cog break
and they do the same symptoms.

Yep, checked that yesterday, and it was getting spark at no.1 lead and then also across the plug gap when I connected it and earthed it.

With the timing, I guess Im just jumping at shadows. Youre right Jim, it was running fine with the dizzy and timing as it is.

get a can of "start you barstad" check timing and the rotor is turning when you hit the key
ps try better battery by now if you can
another trick is to pour 1/4 of a cup of fuel straight into the carb primerys if spark is there itll start or cough or backfire .
GIVE THE CAR NO CHOICE.

If you havent moved the dissy, dont worry about the harmonic balancer, it has probably rotated on itself. Replace it later, its quite common.

If the plugs are wet, its flooded. Either clean & dry them, or replace them.

Have you still got oil pressure? The oil pump may have packed it in and no pressure to pump up your lifters? Is it only the one rocker that is loose?

It will still start with no oil pressure to the lifters, it will just be noisy.

Oil pressure seemed okay, low at idle with warning light flickering but increased with revs. Only one rattling lifter.

Checked plugs 1 & 3 this morning after a few goes of pumping the accelerator and cranking the starter and they were slightly sooty but dry. Didnt have time to check the rest, had to go out. On way back I bought some of the Start Ya Bastard and gave it a go. I had one sort-of promising backfire and ignition (I think) before the booster battery ran out of juice. Have to wait now until I get that charged, will still check fuel delivery and clean plugs for the hell of it.

I just cant believe its so hard to start!

Im beginning to suspect the coil is not functioning as it should. I measured 1.2Ohms from the +ve to earth, when it should be 0.5-0.7Ohms. From the +ve terminal to the HT connection on the coil it should be 5-7kOhms, and its 8.2k by my reading.

Im no mechanic (as if that wasnt obvious) but it does feel to me like it isnt getting enough spark. If its getting fuel (which it is) and enough spark it should at least try to fire. It doesnt even give a hint of firing.

I tried drying and cleaning the plugs, Ive tried a little of the starting aerosol and then a lot of it - nothing works, except for once when the carby emitted a puff of backfire just as one cylinder seem to fire. Once.

Ive checked the spark at the coil lead and also at the spark plug, and there is a spark at both. Its strong at the coil lead as from seeing a sparking plug years ago it also seems strong at the plug.

Im thinking of spending the $65 for a new coil this morning or calling the NRMA to see what they reckon. I hate attempts at repairing by part replacement but Im fast running out of skill and patience on this one.

It was the coil.

Put in a new HEC716 and the engine fired up straight away. Its lifters are as noisy as and it has a hesitation off idle but Ill sort those out later...
