I did check the timing with the light it was at 5° BTDC but I didn't put the ICM in diagnosis/adjustment mode I didn't know how but the mounts are fine I checked them before I put the engine in and it runs ok at higher Rpm like when the choke is on it just at lower rpm it runs rough but the carburetor is not at factory setting all the adjustment screw are messed with and the catalytic converter is good I tested the back pressure I'm think it might be a carb issue
