Hi adam,1-remove the fuel tank,drain your good fuel into a tub and unscrew the fuel tap carefully as it is plastic,pull off the little gause filter and wash it in petrol and put it all back together.2-wipe the out side of the carby with a rag and unscrew the brass nut(main jet)that holds the white cover where the fuel hose connects,take off the cover and clean the little needle and seat and float-take care not to lose the needle and care of the "o"ring on the end cap.put all that back together and line up the horizontal line on the primer cap(where the fuel line goes)3-the hoes that goes to the bottom of the engine is for vacuhme,the other hose connects to the decompressor(round thing)if the decompressor is not working replace it with a spark plug just to seal the hole and block off the hose.if you do this you will notice the pull cord will be harder to pull due to full commpression on start up.hope this helps a little...ken
mower man, the decompresser has a hose running to it. Isn't this the hose that delivers fuel to the otor? You are suggesting that i block it off. If it isn't, that only leaves one other hose (the vacuum one) which i assume does not deliver fuel. Or is it delivered through the mount connecting the carb to the engine? Sorry, i have no idea about mowers!
I will try all of the above and report back. Thanks.
