    First post and first rebuild of a 4tec motor, can you time one 180 deg out

    Picked up my first 4 tec ski it a 2005 rxt 215 sc ic , It had a blown motor in it got it cheap. Rebuilt the motor did eveything by the book got it togather and it acts like it is a 180 out on the timing is this possible and if so how do you fix it i have both the tools crankshaft locking tool and the camshaft locking tool and i made sure the the camshaft gear said 1503 ___ 1503___ lined up with the head with all my tools in. im getting compression on the 1 cylinder but nothing on 2 or 3.

    are you 100% sure that the crank tool is in the crank alignment hole? It can also miss the crank and be threaded down. the only other thing I can think of off the top of my head is hanging valves

    Cyl #3 has to be TDC, which is the cyl to the front of the ski

    Take the rocker shaft out completely lock cam and crank loosen tensioner recheck your timming. I think your cam timming is off meaning your sprocket is indicating 1503 but your cam it not in right position

    You thought right. If they measue within spec they are okay to reuse.
