Pocket rocket engines are derived from Weedeaters and Chainsaws where gokart engines are derived from lawnmowers and waterpumps. 49cc is a pretty good displacement size for that little engine but one thing for sure is that you are not going to mow your lawn with a weedwhacker and you are not going to whack your weeds with a lawnmower. A pocket rocket engine is never going to put out 5 horsepower without serious expensive modifications where a gokart engine easily will. Gokart engines rev lower but have more torque where pocket rocket engines rev higher and have less torque. For a gokart, you want a big engine. Lawnmower (horizontal) style, not weedwhacker style.
