": I have a 86 Gyro. when I first start it. I give it gas but the noise the engine makes is ruff. I don't know whats the matter.<p><br>I owned a 1986 gyro that had the same problem, to solve it, i removed the carb and cleaned it, then i took the electronic selinoid that is on top of it off, and replaced it, mine was all broken up inside, afterwards it ran like a charm. Also, you might want to check your fuel filter, and clean it every once and a while, My tank was rusty and it clogged up alot, i eventually sealed it because i didn't want to clean the filter anymore. Email me if you have any more questions<p><br>Ryan<p>"
