RE: DL-50 engine
I have run a DL 50 with over 40 gallons (3 years old) and my DA50 (3 years old) with over 30 gallons thru them with the ORIGIONAL factory ignition on A123 with no regulator. Both are still running great. I have a buddy who has replaced two ignitions on one DL55 in less then 15 gallons. (He never protects the spark plug wire with hose).
