I bought an 02 GTI last year, it is my 1st pwc. I did not have any issues last year and it was fun. This year has been a different story. It starts fine and runs good for 1st 10-15 min. but then it starts to bog down and only goes about half speed, less in turns. I can let the trottle to idle and try to take off again and it will start to take off at full power but after 2 seconds its back to half power. If i let it sit for an hour or so i can gat another 10-15 min. of fun out of it but then it is back to half power or less also if i pull the trottle all the way open when it is running good it will instantly bog down. Any movment up or down in the trottle will cause it to bog. I have cleaned the carbs but have not rebuilt them. Cleaning seemed to help at 1st, it ran longer before bogging down. Does this sound like a carb problem? or is it something else? Any help is welcome- Thanks
