No, actually I don't. If the crank gear is fatter than stock, then try contacting the manufacturer of the timing set. Have you measured yet? I really think the problem is either with the balancer binding. Another way you can verify if the balancer is bottoming out on the crank gear is to apply liquid paper pretty thick onto the end of the balancer shaft (where it would contact the crank gear), and re-install the balancer, and torque the balancer bolt down. Then remove it, and inspect the area you applied the liquid paper to. If it bottomed out against the gear, there will be liquid paper on the gear, and some will be missing from the balancer.
Or...
You can just pull the pump and cover off and inspect it straight out. Compare the two crank gears, make sure the gear is seated, try installing the balancer, and see where it's binding, etc.
Take care
