G'day Mate,
It needs more prop, a 13x7 is not enough load, it is a 4 stroke, & must be run like a 4 stroke, I would try 14X8 APC, & retune.

I tried a 14x6 MA prop, same thing.

If you have not leaned the low speed needle you need to do that after you switch props and retune the high speed needle.
I leaned out the LSN almost 1 full turn..... Still plenty of smoke and doesn't bog down the engine when I go WOT.... so lean out the LSN more?
