There is no vendor bashing on this site so I will tell you both my reman engines came from Recon......which is located I think in Pa.I have heard they do some real fine work.....LOL........My next qhestion is at 15 to 20 psi and at say 2300 rpm will this hurt the engine.I realize that probably 30 to 45 psi is usual but can I run it for a couple weeks untill I can get them to check it out or should I wire the throttle wide open,crank it and run like hell?
