Hmmm,that'd be good,Nosram .15 perhaps..? Ordered my carriers today from Prado hobby shop aswell as the turnbuckles you advised on so it'll be upgraded this time next week.the top arms can be done Friday and the bearings are ordered too.The wifes is a standard NL.15 engine but was a little more troublesome to start and keep running than this new one,its great now its run in though..
