Hi,
I would change the oil mix to 25ml of oil to 1Lt of unleaded.
I'm probably going to get some arguments here but 25:1 ratio is to strong, it causes plugs to foul up, exhaust ports to carbon up, mufflers to block, blow blue smoke all the time, makes it hard to start from cold because of oil sitting in the carby, and reduces power.
I've run 25ml to 1Lt for 18 years in all mt 2 stroke equipment and never had one seize up yet.
To much oil can also give to much compression as well, can't pull it over without the decompressor.
Well thats my opinon.
