i pump it a couple of times and then hold about 1/2 down, this sometimes works after a lot of cranking.

Sometimes when hot, the gas will percolate into the manifold, and the mixture will be too rich when you hit the starter, so by cranking with no throttle, it pushes this out into the tailpipe. | | | | | Joined: Jan 2010 Posts: 4,263 Shop Shark | | Shop Shark Joined: Jan 2010 Posts: 4,263 | Have you checked the condition and operation of your heat riser valve and counter weight | | |
