Not so much today, but back when starting fluid was mostly ether, you could blow the reeds out, or worse, blow the block apart using to much starting fluid. 2 strokes compress the air/fuel mixture on both sides of the piston(cylinder and crankcase), starting fluid used to be volatile enough that the compression in the crankcase side was high enough to ignite the starting fluid in the crankcase(starting fluid can turn your gas engine into a diesel since it compression ignites fairly easily). This mostly happened in older crossflow engines because they had alot higher crankcase pressures than loopers. I will say on reedless 2 strokes like lawn equipment where they use the piston passing over the ports to act as the reed valve, they have pretty high crankcase pressures to make them scavenge, and starting fluid is a huge no no in them because of it. They could easily ignite in the crankcase, and blow the crank seals out.
