Design and development
The 133M is based on the earlier Verner 1400 and uses a 12 volt 1000W electric starter and has a 12 volt 160W generator. It runs on 95 octane automobile fuel or 100LL Avgas. The recommended time between overhauls is 1000 hours.[1][2][3][4]
The engine was still advertised for sale on the company website in 2013, but by 2015 was no longer listed as available and it is likely that production has ended.[5]
