SOLD! Re: Cox engine parts SOLD to Mark from Oregon

But are they as reliable as Cox heads? Personally-I have two theories-one: that the elements are not Pt or Pt group metals-but rather nichrome or similar-as was used in the early days by some cheap glowplugs-or two: that they use a base metal element with the thinnest possible plating of Pt over the base metal wire-again a generally substandard performance and short effective life results. The 074 heads are the absolute pits-most of mine will only sustain running with the battery connected...fortunately the Fox 09 heads fit the 074-again a bit of bench experimentation is called for-now would be the ideal time to do it....except for my dense suburban location :-(

What are the neighbours going to do? Sounds like you Kiwis can't even leave your houses, so they can't come bashing on your door. I'm sure you have bored neighbours who listen to loud music, so just give them a different kind of music! Eyebrows

As far as the glow elements are concerned, a replacement with the Turbo heads is often possible if there is enough meat left to install them. If a normal plug is used then it will not work, but many of the smaller .049 and larger specific plugs can be changed over to turbos. It is just an 8mm x 0.75 tap and a 60 degree countersink for the seat, using a 3/16" hole. Normally the compression is the same as it was stock , or a slight bit more as the tip of the plug is a bit flat. You can get hotter or colder plug choices than with the old NOS antique plugs. Save the old burned out plugs in any case.
