Greg,
If you sell your airplane now, chances are that you may have addressed the major squawks for the benefit of the purchaser. By purchasing a new aircraft you maybe placing yourself in the same position as with your current aircraft.
Depending upon the age of your airplane, the type of engine and the time on the engine, it maybe possible to justify the cost of majoring the engine instead of just repairing the pulled stud. If the engine is an O-200, and since you already have the case split for the stud repair, new Millennium cylinders will restore the 28 degree timing and you will have a fresh engine to boot.
Do not forget to factor in the cost of the sales or vehicle transfer or title taxes in your state. For example, in the sales tax in Michigan is 6%. If your airplane is worth $20,000, than the $1,200 that you would have paid in sales taxes for a comparable C-150/2 could be applied to the major.
