The 250cc can be more difficult because (obvuiously) the cc is larger and the potential for disaster that much worse. E.g.:-
1) Your wrist MIGHT survive a back-fire from a 10cc motor but it's not likely to survive one from a 3,000cc motor. That seems to indicate that larger motors carry more dangers.... and.... 250cc is larger than 125cc.
2) Similarly, you probably COULD stop a 10cc motor with sheer STRENGTH where a rope had caught round the axle...... however.... FORGET it with a 3,000cc motor. Thus you'd have LESS chance of stopping a 250cc than a 125cc.
By choice, I'd make it BANNED to rope/strap-start a kart, particularly on the dummy grid for all the reasons I have said so far. However, I have ZERO powers to do this. I therefore choose to ADVISE against it and issue the BEST advice I can on making it as safe as POSSIBLE! I can see NO SAFE way to do it with less than 2 people (one on the brakes) simply because, if all HELL breaks loose in the WORST POSSIBLE scenario, there is at least a SLIGHT chance that the brake man could STOP the engine!
Damn it; we won't even ATTEMPT to start our TKM with an electric starter unless there is at LEAST a brake-man! A TKM on full-bore produces a PATHETIC 16bhp.......a 250 twin may produce NINETY FIVE bhp. A 250 is a DIFFERENT BEAST and should be treated with H*U*G*E RESPECT!
