briggs vert 6hp fuel prob.

[BAMBY]

engine starts and runs after being primed repeatedly, but then dies about 2-3 seconds later. it runs really well, but then dies like immediately.

after i started it, my friend could keep his thumb over the carb inlet, and work it so it would stay running... air filter makes no difference.

it is on a lawnmower, but if i can get it running reliably, its gunna turn into one of my projects.

i have taken the carb off cleand it minimally, dont think the main jet on the bowl bolt is clogged tho.


now its my turn to ask for some help...
thanks in advance...

If your sure your just not dealing with old gas in the tank, (it happens a lot) it sounds like you need to disassemble and inspect the carb for any damaged diaphragms/gaskets. Then get a can of carb cleaner with a little straw to spray through each and every little fuel passage of the carb. (wear some type of eye protection, it really suck to get this stuff in yer eyes)

If your careful and dont break any, you might be able to reuse all the gaskets and just get away with a good cleaning.

sorry i forgot to mention, but, yes i did use brand new gas.

its not a diaphragm carb... it has a bowl and the main jet is in the bolt that holds the bowl on.

me and my friend were being lazy today, and didnt used carb cleaner or anything... just gave it the grease rag treatment lol.
maybe thats all it needs, just a GOOD cleaning like you say.

thanks for the tips...
