Husqvarna 345 torn back down after piston replacement. Looks like an air leak around the top of the bearings or maybe the plastic flange as it looks like a miniscule amount of sealer was left. Failed a vacuum test. I used 3bond 1211 and let it dry 3 days before attempting to run, and at first it ran well. Wondering if I should attempt the 3bond again, or maybe Dirko as I have both of these at hand. How long should I let the sealer setup before pressing parts together?Any reasonable reply is appreciated.
