For someone like me who has pulled quite a few of these carbys apart and cleaned them out also replacing the diaphragm but never really understood how the diaphragm worked as a fuel pump.
Thanks for the posting well worth watching. The biggest headache with Briggs motors on mowers is the different set ups with the springs, I have been collecting mowers for a mens shed (donated) and quite a few come from the home handyman mechanic who pulls them apart and then gives up and buys a new one, so when I get them most have no springs or the springs in all sorts of ways to be connected.
Tries the patience at times, some of these mowers are not that old.
I have a Masport at the moment which would have been making one hell of a lot of noise when running, so the carby was removed and refitted (not cleaned) springs not fitted properly, and when it would not start I suppose a new one was purchased. The noise turned out to be the cutting disc cracked all around the mounting and had been flogging for a while, yet to get a replacement, will await a donor mower, I dont think the oil had been changed since new and the blades had been sharpened to the point they were only half as long as they should be.
These owners are good for the Mens Shed.
