well I've been battling this restart issue for a while and can't figure it out. I've just added the ofna valve and that really helped my performance but my idle and restart are still an issue. I richend the low speed idle a bit and that kept it from flame-outs in the turn-around after a high speed run but then after three high speed runs with turn arounds it did flame-out and that's when you can't get it to restart. I've changed glow plugs, confimed there is fuel, no air in the supply line, gasket on manifold is tight, tank lid is sealed tight, ignitor is charged etc.. The high speed adjustment seems to be good and I messed a bunch with the low speed idle to try to get it to restart.. no dice. Any ideas would be greatly appreciated.. can't wait till this thing becomes a little more dependable so it's more fun.

thanks all,

Ken
