Since it has been quiet (dead) for a couple of days, I will pose a query
A friend asked me to fix his Briggs quantum 45. He questioned why mine said quantum 50. I told him there is also a quantum 60, 55, 40, 35 and apparently a 30 (though I have never seen one and believe this was dud info.
He said so different CC makes different power? No, all are 190cc. Different max rpm? No, all are around 3200rpm.
Then how the hell do they get double the HP?
Only thing I could say was briggs did get done for HP cheating, but surely not to that degree. Do they strangle them with the carby, or governor system
Its honestly something I never thought about
How do they do it?
This is from a 1990 briggs yearly bulliten I have, and shows some difference in torque curves, but I still would like to know exactly how they do it
