I have an os 46 la on a four star 40 that weighs 4.25 pounds and I love it. It always starts on the first press of the button on the starter. I have never had a deadstick. That engine ran great even on the first run out of the box. With that engine it has unlimited vertical. I also have a cub with a magnum 52 4 stroke and I HATE it. It doesn't start worth a darn and has a terrable idle. A few more engines that you shoud avoid are ops and saitos and rosi. They give a new meaning to deadstick.
