Re: Mine died today
If it didn't hit by injecting fuel directly into the carb and you have a good spark, I would double check the timing. Pull the carb off and spray a couple squirts of gas directly into the intake, I wouldn't rebuild that carb until I got the engine to hit.
Re: Mine died today
I'm beginning to think he has a timing issue of some kind.

Re: Mine died today
It may sound basic but By any chance did you take out the distributor and reinstall it 180 degrees out?

Re: Mine died today
We also wonder about the timing, however it seems unlikely that could change after driving a while, then park and try to restart. We have checked by the position of number 1 piston and the rotor which is correct. Currently working on getting my timing light functional to confirm (or otherwise) it is correct.

Re: Mine died today
Have you tried a clean set of plugs? Injecting gas with a squirt bottle will flood it in seconds and after that the plugs are crap. You can try heating them up with a torch to burn out the deposits but do not get the threads or especially the ground electrode red hot. You just want to burn out the gas residue that is left behind on the porcelain.

Re: Mine died today
I'm just going to throw this out as food for thought. There was a guy on youtube (Jalopnik, I think) and he was attempting to drive a very weary old flat-fender up to MOAB. Ultimately, the engine died (no surprise there if you happened to see the video) and no amount of coaxing would get it to start. In the final analysis, the timing gear (a composite material of some type) had come disconnected from its center hub, so effectively the top half of the engine wasn't in time with the bottom half. In his case, the ignition timing was set correctly (but remember, that's coming off the bottom half of the engine) but the compression was pretty much non-existent.
Now, before someone states the obvious, I am not attempting to equate our engines with that of the early Go Devil motors in any way. What I am trying to illustrate is, when all the obvious stuff seems to be right and has been double checked, it is time to start looking at the not-so-obvious stuff.
Like the old saying goes - When you hear hoof-beats, think of horses, not zebras. But if no horses come by, start looking for zebras.
So, it seems to me the easiest thing to do to eliminate a jumped-time issue would be to check that compression over all four cylinders.
Cheers,
TJ

Re: Mine died today
Another sad, frustrating day. We have four timing lights and have had trouble getting them to work (all work on a GPW). Finally one worked long enough to check the timing and it is spot on, so there is one issue resolved. However, we still have problems getting any of the timing lights to work consistently despite having a nice spark when we remove one of the plugs and earth its body. Once more pulled down the distributor and checked everything, even put the new shiny coil in but no difference. Checked the battery voltage at 23.6V under load from the starter so that seems OK.
All we can think of now is that maybe there is a distributor fault. Have checked for cracks, tracks and (can't think of a rhyming word) other things but nothing appears wrong. I am going to ask a guy in Brisbane if he has a spare he can lend me to check that out.
My mate who has been working with me is a diesel mechanic but has lots of experience rebuilding GPWs, blitz buggies, etc but we have another mate coming over on Tuesday who is an old school car mechanic who may pick up on something...
In the meantime open to suggestions?

Re: Mine died today
hi
i have not reed the whole story
if you use a timing lite it must have the 12v from the mutt
it use the ground
can you turn the rotorarm a bit by hand
if you let it loose it must go back at his begin point
if not meybe the two spring from the advance are broken
if so the timing can more than 40 degree off
greetings george

Re: Mine died today
The bit about the timing lights all not working sounds to me like a clue, it sounds like you do not have consistent spark. Have you replaced the capacitor, or better yet, bypassed it on the inlet of the distributor?

Re: Mine died today
A standard timing light will not work on a shielded ignition wire. The electromagnetic shielding blocks the pickup from sensing the spark. You can use an old wire and cut away a portion of the shielding or you can use a piece of wire core spark plug wire with the ends trimmed off and shoved into the distributor and plug.

Re: Mine died today
Also, as George said above, if you are using a 12 volt timing light and hooking the ground to the body, you must hook the positive to the positive terminal of the grounded battery or you will supply 24 volts to the light and ruin it with the excess voltage.

Re: Mine died today
The safest way to get 12 volts out of a 24 volt system with two batteries is to just hook the leads to ONE battery. Positive and negative of the same battery and that way you can only get 12 volts, no guessing on grounds to the body. If you ground to the body and hit the wrong positive terminal you get 24 volts.
I assumed you already knew about the shielded wires not working with a timing light, just find any old plug wire and stick the ends in the cap and spark plug. It will work for timing the engine.

Re: Mine died today
Thanks guys. I am using a wire lead to number one plug and have the timing lights connected to the earth side of the batteries and the positive side of the battery that is connected to earth sol I am getting twelve volts. Will follow up on George's suggestion but I had noticed it returns although I had not specifically checked it.

Re: Mine died today
kmam, I'd still very much like to hear you say that this truck has had a successful compression test.
Re: Mine died today
It is a brandy new, built from the ground up engine. Granted a compression test would be good but to go from running one minute to dead the next is not likely compression related.
