I been trying to get the KT7 to run right and I have had a little luck but not much else . I finally said enough and hired a mechanic to go over anything with a fine tooth comb . It just would not idle correctly . It took him about 10 minutes to find the problem. The fuel pump hose was crimped shut allowing very little fuel into the carb . He fixed it and told me to go run the thing and report back as to what else I want done . I was not here when he did the work but the wife said the old girl just purred after he finished . I been busy with business but plan to take her out this weekend to check hydraulic speeds .
