Ryobi 725r, ran out of fuel,very fast idle. Could not restart, replaced brittle fuel lines, 1/8 inch ID by the way. After several weeks went by I tackled it again,got it to run good but hard to start, kept finding plug wet. After drying it off it cranked OK. HAd the same old problem of which line went to the primer and where. Now 1 push on the primer,choke on and it fires right up but more than 1 prime and it's flooded. Is it possible that I have a fuel leak thru the carb into the cyl albiet a Small one?
