i have a 1996 dt25c. i bought the motor from my neighbor after it had sat for about 10 years. he passed in 98 and in his log book, i can account for about 37 hours run time. excepted for a few runs on the hose by his son the motor has not seen the water in some time. here is my problem. i am in the process of rebuilding the carbs but i also seen on a post that a dt25 should have about 120psi on a compression test. i have 80psi across all three cylinders. am i wasteing my time on the carbs? any info good or bad?
