Hey Guys, My Engine is running great, but it is difficult to start. It idles fine after a minute. And revs great. Did a plug chop and I'm running just about perfect, a little rich. Why is it so difficult to start? It acts as if it has trouble pumping the fuel at first, but the carb is rebuilt and clean same with the gas tank, also good gas. I tried turning the idle up a bit to no help. Thanks Guys

The first two pulls should be purely pumping fuel into the primer cup. Does it start on the 3rd-4th pull? If this is very hard consider a can of starter fluid.

No, this is going to start an argument. In my opinion, Briggs and Stratton make some of the worlds sh!test carbies.
And that solomon, is why your engine is difficult to start...
Thanks

I Will agree that Briggs does make MOSTLY crappy carburetors, I have had some real nice ones though. But this thing use to Fire on the first pull and run on the second.

Set your idle to 1,600-1,800... the clutch does not begin to engage until 2,000 rpm.

When I had a flathead something was seriously out of order if it took more than 3 pulls. Unless you run it dry the only thing the carb needs to do from a cold start is pull fuel about 3/4" up from the internal bowl to the jet. I always just set the choke and gave it a yank, 8/10 times it would be idling and ready to run after I pumped the throttle a few times to warm it up.
People like to rag on briggs vaccu-jet/pulsa-jet carbs for some reason. I love em because they are dead simple, there are 2 screens to clog and 1 diaphragm to fail, its **** near bulletproof.

your engine is trying to tell you to that you need a work out..

Check the clearances on the valves. Is it easy to pull over?
The valve clearance is a little more than it should be, but that's because I like to feel the compression stroke really well when i pull the engine over. I do like these carburetors as well, just hate when they don't work. I will try turning up the idle speed again, and i will check to be sure everything is tight and no air is trying to leak in.
Well i wire wheeled the spark plug and tightened the 3 carburetor to tank bolts about 1/12th of a turn each and turned the idle screw in about 1.5 turns and now it starts right up like before! I hate how high the idle is but, whoever buys this kart can deal with that! Thanks EVERYONE!
