i am currently running a early 2000's 5.5s briggs intek OHV. for a while i was running straight air, no filter. this was partialy because of a small fuel leak out of the intake. this was a minor headache but the (free) engine still ran, so it was cool with me. one day my brother comes up to me and says the engine wont start. fuel level is good, so i cranked on it and got it runinng with some coaxing, but the bike would only run on 1/4 choke. i looked for gasket malfunctions or anywhere it could be getting air. even through the airfilter on for good measure, still wouldnt run with no choke. so i took the carburetor apart to see what i could see, and found little red chunks of gasket in the 'hole' the pin for the fuel inlet sits. not knowing i tryed pickin out the chunks. put everything back together and the carb belches out fuel in a steady stream. were those red chunks an essential gasket limiting fuel intake? have i screwed over my engine? any advice or ideas welcome. if you have any questions ill answer because my description is somewhat ambigious... thanks
