How many people have to tell you that there is something wrong with the PRIMER since you are not getting a squirt of gasoline when you push the primer bulb??!!

I lost count.

"throw is against the wall long enough, eventually something will

OK, THAT'S (the PRIMER BULB) what I keep checking and THAT's what
continues NOT to spray out gas despite cleaning it and the screen
underneath, replacing nearly all the gaskets, removing, cleaning and
reseating the primer bulb..... what more could I do??? I don't see how
I could be reseating it improperly as there seems to be only one way to
install the damned thing. So, with the new air filter assembly, will
also come a new primer as well. I hope this cures the problems because
I don't know of any more alternatives.

Some of you folks don't need to get nasty or impatient just because the
suggestions you keep aiming at me aren't doing the job. To the others
who are showing the appropriate courtesy and patience, I thank you. One
way or the other this "dog" will be fixed.


Somehow most of the posters think a 4-cycle B&S sprays gas by pumping
the gas thru a primer bulb. It does not.
2 cycles pump gas thru the carb but 4 cycle B&S use AIR PRESSURE to
force fuel up thru the jet to the throat of the carb.
The backcheck pressure bleed under the welch plug is probably
thoroughly crudded and needs to be rodded out and cleaned per the B&S
carb repair guides.


Can you provide me to an online resource for doing this task? I noticed
one
or two metal plugs were included with the carb kit
and I wasn't sure of their purpose. I did not attempt to touch these
when cleaning the carb. I have some version of the B&S manual for this
engine, but the content seems to cover several carb versions and I find
it difficult to pin down exact information.

Thanks,
Jason
