I did not use my Donzi last year at all because I drove my Formula every time out. This year after looking what I spent on gas in the Formula I decided it was time to use the Donzi more again. Well all the sudden I am getting TONS of crap in my filter at the carb (I assume the canister filter as well) and it is impossible to keep the boat running at idle after I go out on the lake unless I mess around with the carbs idle mixture screws. Take out and clean the filter and it runs well again. Some one said that there was talk about something I can add to the gas to help clean out the tank? The stuff in the filter is not white like I have had in the past that I clean out once and I am good for the rest of the year. This stuff is brown. Looks like the Ethenol is cleaning off the old shalac in the tank? Any help would be great. I am going to try and put a new canister filter on this weekend and see if that helps. Any other ideas?
Thanks
Jon
