Most of the other stuff to try requires no real money. If the motor is overpropped for the boat it'll do the same thing, ditto if the carbs carbs are too lean, or the timing and sync is off.<br /><br />When he went to school in 1980, the reed blocks from a 1957 Tower Of Power were 23 years old. It was harly a radically new design.<br /><br />If I'm not mistaken 1979 was the changeover year to ADI - I think early 79's had distributors.<br /><br />To test the reed blocks (after exhausting prop and adjustment issues) try doubling the oil and see if it helps. If it does, then it's time to consider them as suspect.<br /><br />As a major player in the Inline 6 overhauling market, I have to say I rarely see bad reed blocks in the fishing motors.<br /><br />They used those type blocks on the 4 cylinder Super Thunderbolt from about 1949-1999, and on the six from 1957-1988, hardly an unproven design.<br /><br />I'm not saying they can't get worn, especially the center one, but it's more likely to be mis-adjusted or overpropped as opposed to having worn out reed blocks.<br /><br /><br />-W

Steve, Why must people like you, continue with your ranting and raving you only expose yourselfs for what you are, I enjoy this site and most of it's members, I belive that good advise does not start with a doomsday scenario maybe you do. Thats just a differance in opinions. As far as your remarks, I guess I asked for them, by mine, if the shoe fits wear it.---Bob

You forget, he was trained at Brunswick, where the *real* underlying agenda is to get the old Towers off the water in order to sell more of those 2+2 frankenmercs. They just repeat what they are told and "shown". Me, I personally own about 200 reed blocks, I bet less than 1% are hosed.<br /><br />-W

you guys argue back and forth like little kids. . . i registered just to fix this problem for him. . . its very simple. if youve replaced/rebuilt the carbs and pump. pull the intake cover off. . 9 times out of 10 the bleed restrictors have made their way out and simply floods the clyinders. ive worked on many inline 6's with the exact same issue. such a small part causes so many headaches
