That 125 sounds like it came off an Imperial. Having used mowers with a 3.5 hp B&S ad a 160 full cranker with both a G3 and an LM carbie I would say that the 160 feels more powerful Perhaps the relatively low HP figure is due to the restrictive muffler set up.
It sure did! To me, Briggs always feel less powerful until you get to the 6.5HP model, which feels about the same as a Victa to me, I think Briggs don't much in the way of low end torque. On a go kart a Victa feels more powerful than a 5HP Briggs too.
Anyone got that torque curve?
Thanks
