I have replaced impeller, carb kit. Engine is running but every time I throttle to fast speed Engine rep up as it supposed to do but in 30 Seconds on fast speed mode it drop down. By meaning once throttle is in fast mode the bower of the boat elevated up for 30 Secs and it flat out, parallel to water surface, this repeated constantly. As you can see I'm a beginner on this type of work. I really need your expert opinions on solving this problem, please HELP! I also have made some adjustment on the low and high orifices needle, I thought it doesn't have correct amount of gas/air mixture, but it seems like it not the case. PLEASE HELP. Thank you so much.
