In the UK at least some Shell V-Power contains ethanol. My local Shell garage was ethanol free until the day after they refurbished all their pumps (perhaps the old pumps were not ethanol proof?)

I posted a suggestion as to how aluminium wing tanks might be retro fitted into a wood spared Pulsar wing. Someone suggested this solution might fail if the tank could not accommodate wing flexing. G ...

I guess that if ethanol had been present in mogas when the early Pulsars were designed the tank design would have been different. My MK1 582 pulsar has wooden spars and an integral fuselage tank, a ...

If you can't get composite spars would it be possible to construct spruce spars as per the earlier Pulsars? I guess in this case the MTOW would be limited to that of the earlier Pulsars.
Perhaps so ...

I have a Rotax 582 with a warp comp prop in a Pulsar. The engine has the oil injection system fitted.

Because of the slippery Pulsar profile (5000rpm and 90 knots at 12 litres/hour) EGTs tend to n ...

George, sorry for the delay in replying. I had to take some photos of the louvers -see pictures on the Picasa link at the bottom of this message. The guy who built the plane and fitted the louvers op ...

Hi Barry
I'm replying to your email in serious mode just in case you were being serious and not "pulling my leg"

Plug manufacturer NGK make no reference to combustion temperatures being ...

Hi Barry,
I can't see that a plug temperature range will affect the (true) cylinder head temperature. My understanding is that the terms hotter and colder plugs refer to the thermal coupling betwee ...

I don't see how a CHT thermostat properly mounted in a small hole between the plugs can do anything but record the true CHT temperature.

I can see how a thermostat crimped into an aluminium tag t ...

I converted my new blue top to grey top mode when I fitted it by blanking off the two ports where the bi-pass hose would normally fit.

The original builder/owner of my plane did not fit the thermo ...
