Sir,

Nice to see a product that works as advertised.

Best regards,

I had lead build-up in the valves of my O320 (Glasair). I had the Lycoming valve cleaning treatment done at Ascutney Aviation, and after that used Decalin RunUp every time I added 100LL. I never had any lead issues after that (that I was aware of anyways).
