Ok have a 15 year old 4hp Techumseh motor with float carb on it to work on... Apparently been hard to start taking about 20 pushes of the primer bulb to make it start when cold, warm starts are just fine. I have taken the carb off cleaned all passages I could get to with carb cleaner and air compressor, cleaned the fuel tank and fuel line, replaced the plug, new oil, new air filter. I did clean out the small holes in there on the thing that the float goes around and the bolt that goes into it...Float had some fuel in it so I got a new one. Put it all together and still takes 20 pushes to get enough fuel to start. Last effort will be the primer bulb itself in case it has a leak..it never gets hard when priming it. Thanks for any help.
