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. Jim Stone .. 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?

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. Vern ===== Vernon R.
