Rusty. Check to see if that is Briggs Ready Start system. I have an old one and it does give a lot of problems. Cold weather or after sitting for a week or so, I have give it a shot of carb cleaner to get it started. http://www.briggsandstratton.com/us/en/support/videos/other-engines/the-readystart-starting-system https://www.youtube.com/watch?v=wUEwSKFFsqE. It is an automatic choke but it does not always work as advertised.

Farmerdill, excellent You Tube info,

Rusty, people will say anything. But, there was a system like that. I was called a Lake Injector.

It was used on motorcycles to get a injector type fuel system. I had one on my 650 BSA and it performed really well. The problem was you had to shut off the gas valve while you were parked. Or you lost a tank of gas

It never needed to be coked It worked on gravity. And the gas tank was above the carburetor

Look up Lake Injector and you will see that there was such a animal.

Well, I took it back to the owner-unfixed-and told him to take it back for a refund. Never heard what happened for the owner. And, I haven't seen gas run uphill, without some kind of help! RJ
