Hi everyone. My Bushranger line trimmer bogs down when on full throttle. The only way I can get my line timer on atlest about 70% power is when I have the throttle about half way open. Please I need advice on how I can get it sitting on full throttle putting out full power.
Pull the muffler off and check the exhaust port,it is probably half the size it should be. Make sure the piston is up before you start digging the carbon out and blow it out before you move the piston
I just wondering if you tried ever soaking these engine ports and the cylinder chamber with de-carbonizing fluid? I know it works on Stihl handhelds that are completely seized up by carbon. On several hours and application refills those engines start to free up to where they will start. At first they start and run poorly belching lots smoke as the carbon then burns off. This smoking will start to clear and engine operation will start to improve until all the carbon and de-carbonizing fluid burned off.
Here the Stihl de-carbonizing fluid is hard to get so I use the AC Delco vehicle de-carbonizing fluid.
On stuck engines you do have to make sure they weren't straight gassed first.
