I have an older stihl 028. The saw starts and idles nice. As soon as you throttle up or put it under load, it bogs out, It also seems a little smokier, Can ya help? I cleaned the carb and jets and exhaust screen.???

First check your fuel filter. Its on the end of the pick up tube in the fuel tank. Could be clogged. this is a relatively easy and inexpensive place to start. Make sure the fuel supply isnt pinched anywhere along the way.
Could be a scored cylinder. A scored cylinder is common problem with all makes of chainsaws. If you dont take special care to keep the air filter clean and in perfect working condition, the wood chips and dust will enter the combustion chamber and score the cylinder walls, ruining the rings causing a loss of compression.
The piston could also have been damaged from running to lean of fuel to air mixture causing heat damage to the piston and cylinder.
Hope this was helpful. If so, gimme a thumbs up vote!
