| Subject: | Starting problem- solved |
I pasted my original post below describing my starting problem for your ref
erence.
I would like to report I have found the solution to my problem. After a ver
y thorough troubleshooting effort throughout the electro air system and my a
ircraft wiring, I was able to isolate the problem to the magnetic sensor. O
f course I had to remove the propeller to get access to the sensor and the c
rank shaft timing wheel or CSTW. Even though my existing sensor omed-out in
the normal range, it apparently was giving a false positive. I replaced th
e magnetic sensor, propeller and the engine start experience return to norma
l. Both cold and hot starts are similar to the starts I experienced before r
emoving the impulse magneto. Thanks for your help, hope to meet you guys in
the near future.

I'm looking for ideas to improve my start up both cold and hot.
I have an IO 540 C4 B5 with a non impulse mag on the upper plugs and Electro
Air Electronic ignition (latest version on the lower plugs), and all aviatio
n plugs.
I removed the slick impulse Mag a year ago after the Slick Rep advised me to
"get it off that engine before it comes apart and stops your engine".
I have been starting with just the ElectroAir and realized it is not my star
ting technique as much as it is a lack of spark. ElectroAir told me that th
e system has to measure a pretty fast cranking speed for what seems like a l
ong time before it produces a spark. This cranking pulls the battery voltag
e down and if the voltage to the ElectroAir controller falls below 11 volts,
it no longer produces a spark. Of course I have no indication of no spark o
ther than the obvious no start result. So with some luck the batteries hold
up long enough tilI I get the mixture right, if not, recharge and try late
r.
I'm considering the slick start but it requires a different mag from Slick a
nd a coupler which all together cost 2k.. Seems like a big price to pay for
better start performance, but I'm considering it.
Does anyone have a proven solution?
TIA,

Wasn't that your new paint job on VAF today? If so---WOW!

Thanks for the explanation. BTW, I put a blast tube on my pickup. I took o
ne apart to see how they are made and concluded that keeping them cool would
help.
