This new Enya may be OK. I seen & heardaengine ina Big warbird that ran perfect. I asked the guy what engine he was running....it was a Big Supertiger 3000 series and he said it never ran good untill he used L85 pump gas & a Hot 4 cycleO.S. Max"F" glow plug. Maybe that Enya is High compression and will run good too.........
