Ok, I've had this thing for a year, working on it off and on and I CANNOT figure out what the hell is wrong with it. The engine doesn't seem to be running at full RPM. The timing is perfect, there are no air leaks around the engine, and I just put a new base gasket on it. I can only get up to around 20km/h. KM/H!! The compression is good too, a little over 120. Has anyone ever had a similar problem? Could it be something mechanical, like the variator or the rear pulley? I know the engine isn't reving as high as it should. I really don't know what it could be. Any help on this would be much appreciated.
