BRIGGS AND STRATON CLASSIC 35 RUNING PROBLEMS

[angellonewolf]

a little help needed if you can some pics and vid it might help



a little back ground i rescued this from the tip some one was going to chuck it said its been left out side for a year
after a quick look the cable to the spark plug had been cut i had a spare so put it on and did a spark test and that was fine
then went to the carb and fuel tank took them apart cleaned the fuel tank and used carb cleaner on the carb and all holes
filled with new fuel and primed and started first pull

sorry forgot to add that i drained the oil and filled with new

now to the problem it runs fine for 10 to 15 seconded untill the prime fuel i think runs out and then starts searching revs up and down and does not stop

any ideas

thanks for any help

You need to replace the diaphragm and gasket between the carb and tank.

any idea of the part number ?

from a quick look P/N 795083 thanks angel

 

[Rivets]

From your description very confident. 795083 is correct. Make sure you install them properly, diaphragm agaianst the tank, gasket against the carb.

Thanks for the help rivets

That was going to be my next question

In my rush I bought a 3rd party copy part instead of a Briggs part
What do you think on copy parts I assume there ok but generaly don't last as long

Thanks again for the help

The bits of rubber of the diaphragm did seam to be a bit hard and not flexible

I always try to use OEM parts. I know what I am getting and if I get a bad part I can return it, even if it is used. You must remember that I am a certified technician for many engine manufacturers and it is in my best interest to use their parts. Plus, my reputation is toast if I use non-OEM parts and the unit comes back.

my fault should have read the description better but hayho they have been posted so will just have to try them
the cost was about half the price of a oem set so will have to hope they do the job looking at the comments they do ok

again thanks for the input will post on the fourms i hope in a day or so depending on time scale of the postal service
