I am having trouble figuring out a problem on my RV 8 with a superior 0-360 with bendix FI and two slick 4371 mags. The plane will start and run fine, but when I do a mag check, the engine dies when turned to L. I have checked the switch, and tried a replacement with the same results. The wiring seems fine, and when I pull all 8 plugs and spin the prop by hand, the plugs all produce spark when they should, whether the switch is on both, left, or right. The engine is a used engine, with 192 hours. It has been in storage for a little over 2 years, with storage oil and oil in the cylinders. I am just changing out the storage oil for regular oil, and was planning to run the engine for a while tomorrow to try and warm it up and clean the plugs off.
Could it be a simple fouled plug problem, or where should I look now? The plugs are a little dark, but the spark seems good when I spin it by hand. I can't seem to make any headway.
Thanks in advance!!
