i have a 92 saltwater 125 and went out on sat engine ran fine onway out. on way in fired her up pulled anchor and headed in. Straight away as we got past 3500 she started running really rough and shaking around and sounding like mot runnin on all cylinders, strangly the fuel gauge only started bouncing from full to empty etc (related???)cut back revs to 2500 and ran for few mins and she settled could then increase power and was fine. Took her out on sunday and ran fine for 3/4 miles then i trimmed engine slighty and bam straight away the same problem with running and fuel gauge bouncing, she never came back around this time. Plugs less than 9 mths old with 20/30 hrs on them. Any ideas ???
