Ok, heres the deal, ive been through two piston connecting rods on my Vmax7 engine even after following the break in procedure. They seem to have broke on about the fourth or fifth tank of fuel. Ive heard from others having the same problem. was wondering if anyone else is having or has had the same problem and what was their remedy. Ive since gotten the engine replaced and have not fired up the new one yet. Anybody out there with any answers ? Also heard that there was a bad lot of engines that went out and that could be part of the problem, I just got a couple of those engines. Each time the connecting rod broke, I sent the engine in and they sent me a new engine back. Im on my third engine. Looking for suggestions and help, dont want to go through this again.
