Please - you don't give it gas to accelerate - you give it air - as you open the throttle, it's the job of the carburetor to mix the correct amount of fuel with the air to support combustion. Ideally, 1 part of gas to 12.5 parts of air. At 14:1 it is lean and the engine produces excellent power, but runs hot. At 12:1, it is rich and while runs well, it wastes fuel.
Most bogging (if not an ignition or compression issue) is caused by too little fuel being mixed with the incoming air. What I do not know is if you have made any modifications to either the exhaust or intake. Just installing a different air filter is a modification and modifications to the intake affect carburetion immensely while changes to the exhaust have a lesser effect on the carburetor settings.
You may just need a thorough carburetor cleaning not just the jets - the passages within the carb must pass air as well as fuel.
