Default 86 /70hp Yamaha Bogs at wot

My top carb. was leaking gas, so I took it to the shop and payed for carbs. cleaning !When I took it out to the lake it would not accelerate to wot..jiggle linkage and it took off and ran ok..next outing it ran fine, last outing was running wot and running fine then the engine just bogged down and would not regain max rpm's. I don't want to go back to shop as it has been several mths. ago when work was done!Also I used Seafoam Deep Creek to decarb eng. any connection there ?? Thanks for your input.....Larry

sounds to me like the problem might be with the float or the inlet needle.

Get a manual and check the synchronization between the throttle linkage for each carb and the linkage between the carbs and the ignition timing. If the carbs were off they might need resynching.
