I have a 1983 115 model TLCTE, and the motor runs great. when i slow down and it idels for a few minuites it will kill. takes a little while to get started again and will run very good a high or medium speed. did a compression check and i do have 1 cylinder that is 95, all the rest are 115 -117-117. could this be my whole problem and what are the corrective measures and possible cost. don't whant to spend more than the motor is worth and will repair last?
