well, there round....just kidding. All the plugs have oil on them, both rebuilds. I've even asked if there is any way oil can get into the gas through the fuel pump, but not get in the oil, or leak outside of it. Everyone says that can't happen. Also, we should be able to see that in the glass fuel filter by the carb. Some have suggested too rich carb washing the cylinders, but the carb checks out fine by my carb guy and myself. No black smoke out the exhaust, just pure blue. (I don't have a gas sniffer to be 100% sure, but pretty sure that isn't it). By the way, the rings are iron rings and have been told they should seal right away, per say. (you may have a bit of light smoke or blow by for a little bit, but in general it shouldn't "smoke" like ours.) All other engines I've done didn't smoke like this. I've used iron and non crome molly rings in the past with no problems. (always used oil in the past on the rings). They say don't use synthetic oil on break in because it's too "smooth" and won't let the rings seat. That's why I come back to the grease issue, for it is defenetly "smooth". I did talk to Permatex, and they wouldn't tell me for one if their grease was ever designed for rings or not, and if they thought this would be a problem. They basically said they didn't know, in so many words. (or didn't want to admite to it?). Thanks again.
