"1999 Merc 115 2-stroke, model

"1999 Merc 115 2-stroke, model # 0G924741. Last year all of a sudden it lost any high end, it really bogged down, wouldn't go over 3200 RPM and struggled to get there. Starts and idles Great though. Took to local mechanic, spark and compression good, shot some carb cleaner in it and tried that. Same problem. Took carbs apart and though they were clean, cleaned them anyway, did not replace anything. Took back out and shoots out of hole strong like its going to run great, it doesn't bog right away like before, but after 10-15 seconds it then bogs out. I let all the way off the throttle and the engine stays reved at about 3000 RPM for 2-3 seconds then idles down again. It will take off every time and run hard for the 10-15 seconds, but then bogs out, revs when throttled back, and goes back to idle. Any thoughts?"
 
"Ben, Try having someone pump

"Ben, Try having someone pump thw fuel primer bulb when the motor starts to bog. If that fixes it, rebuild the fuel pump. if not, you may have ignition problems. That motor may have a high and low speed winding on the stator which controls the spark at high RPM and low RPM."
