Running a wider gap on a plug ... ANY plug, means that you have to develop more voltage to jump that gap. Add compression and the amount of voltage required jumps even higher. The higher the voltage required to jump that gap, the higher the secondary voltage will be on the mag COIL. The higher the voltage is in the secondary of the mag COIL, the more easy it is to have insulation breakdown and failure occur. That's why true racing systems develop voltages upwards of 40 to 50 THOUSAND volts and don't break down when operated at that voltage level. Increasing spark plug gap will NOT lead to longer mag coil life. Even assuming the wire resistance is a tad better or worse than the next guy. A wider gap does indeed give a stronger spark and does indeed lead to better ignition of the fuel mixture. It also requires a higher voltage. Lower wire resistance increases current flow. Total voltage is still increased with a wider gap, and your statement about these features extending coil life are arbitrary and without basis other than pure conjecture and are factually incorrect. The laws of physics still apply. A very simple check would be to test the coil temp with different designs. The inherent hysteresious loss of any coil will cause a temperature increase with a higher voltage and current demand. If the temperature of the coil is decreased with your system at least you would have some science involved with your statements.

Our system, developed over a couple years by friends of WW working closely with gurus in high energy electronic ignition systems, provides the lowest total resistance of any upgraded ignition system for our engines that we are aware of. In addition to the other benefits previously described, one of the biggest reasons for the Iridium plugs is it allows us to run a wider gap and, using our ultra low resistance 8.5mm wire, and still have lower resistance than the other systems out there, which makes the coils last longer. Now, when an electronic system is developed, that will be the ticket.... Hope this helps, Barry -------- Barry Hancock Worldwide Warbirds, Inc.

Does anyone on the list have a baffed out Huosai mag they are willing to sell? Hopefully complete but worn components ok. There was a lad on this list I sold a Huosai engine core to a few years back to replace his cracked block....any mags left over from that one ? Thanks.

The usual sources (George, Steve and Doug) have not seen a set for quite a while. Am coming up blank with possible leads as far away as Australia and Romania. If someone has a spare set, please contact me directly, off the Yak list. I can offer a very good price.

It is a "flex-fuel" engine with electronic control. Note the picture on p. 72--sure looks like automotive spark plugs to me. Interesting. Not much detail in the article, sad to say...
