Re: SureFly Electronic Ignition

I just realized a detail I think needs to be included if you replace the right mag with the SIM, and want both the SIM and Slick Start to provide starting spark. In my plane (and likely all) the right mag is grounded at the ignition switch during the starting sequence. The jumper that accomplishes t...

Re: Starting Trouble...anyone seen this before?

BTW, I've posted some of this elsewhere, but my original Slick Start failed and was replaced some years ago with another. The original clearly failed the prescribed bench tests. It was the replacement that was suspected a couple of years later, but it turned out to be the connection I described. Als...

Re: Starting Trouble...anyone seen this before?

In which conduction connector did you find your problem? Mines the same year as yours. The mechanic in the shop did this: He postulated a problem with the lead to the retard points and fashioned a temporary lead. Disconnected the lead at both ends (#3 SS terminal and the mag retard terminal), repla...

Re: Starting Trouble...anyone seen this before?

Rich, can you elaborate on the conductor connection? Is that science speak for "wire"?! Yeah it's "the wire". Sorry, I used to do all sorts of electric engineering for a living. Bad crimp, deteriorated insulation, even a break in the conductor inside the insulation are things I've encountered in va...

Re: Exhaust and Intake Risers Touching?

Any spacing would be fine. The notion of mutual wear from vibration would be the major factor. The amount of air in the intake pipe that could be heated by the very small area where the exhaust and intake pipes cross is minuscule. Every intake stroke for a given cylinder is trying to pull in 90 cubi...

Re: Starting Trouble...anyone seen this before?

When the Slick Start is operating (powered off the starter relay, BTW), it grounds the left mag p-lead, disabling the 25-degree advance points and provides voltage/current to the retard points instead. In addition, when the starter ignition is selected, the right mag p-lead is also grounded by the i...

Re: Plug replacement

Thanks, Rick. Mine have also performed well all this time. They never foul and just get cleaned at each annual. One additional rationale for replacing them is that with the Surefly half the plugs "spark" twice as much per hour as before, hence overall I have 50% more spark (though not ignition) even...

Well, that works

Somehow my 406 MHz ELT decided to go off after pulling the plane out of the hangar this morning. So I got to speak with an Air Force officer in Florida to tell him all was OK. Good to know the system works :D

Plug replacement

My plugs are the Unison/Autolite fine-wires: UREM38S. They are now 13 years and just over 850 hours of use - something north of 60 million spark events for each. There has been a bit of annoying vibration on and off for the last year (pre- and post- Surefly) and I'm thinking of replacing them at ann...

Re: IFR Currency for Levi - KMRY KWVI (Part 1)

I think IFR approaches in VMC at non-towered airports is one of the scarier things in flying. The VFR planes are flying a pattern and the approach brings us straight in on final. The VFR pilots may well have no idea what we're talking about if we say we're 10 miles out on the RNAV XX. Mostly I find...
