Simplicity 16GTH

Last week I referred to my brother as having a case of "Murphy's Law":(!. Well, hopefully its over. He had broke a rod in his 16hp Briggs V-twin and was looking to rebuild it. We didn't spend much time looking for a rebuild kit because I found an exact match to his tractor. The only problem with the "parts tractor" was that it had caught on fire. All the electrical system, starter and hoses were burned up, but the motor seemed fine. So he decided to buy it for the motor and replace all electrical stuff on the burnt motor with his. It took him part of the day Saturday to swap everything around. He started it up and it ran for about a minute or so and died. The only way we could get it to run was by putting fuel directly into the carb. We checked to see if the fuel pump was working by disconnecting the fuel line to the carb and cranking the engine, no gas came out at all. I suggested maybe the fuel pump was shot, he disagreed. So he decided to take it to the local Simplicity dealer for them to look at. They found the problem and had it fixed with a complete tune-up and linkage adjustment within 1 1/2 hours. Now I know what the problem was but what would be your guess?

My guess would be that the vacuum to operate the fuel pump was interupted. The vacuum hose between the pump and valve cover was burned through, the seals on the valve cover mounting studs were burned, the valve cover gasket was burned, OR the valve cover was warped. Pat

I should have clarified that all the above items you stated were replaced on the burnt engine from the one that threw the rod. So all hoses were good, pump was from the original tractor (not the burnt one) and the valve cover and gasket were replaced.

The tank was the first thing I checked. :D When my brother put engine in he forgot to put the muffler clamp on:(!, so he before he tightened the engine bolts he tipped the engine and slid it back a little, put the muffler clamp on, slid engine back in place and tightened everything up. As he did that he accidentally got the fuel line under the back of the engine[:0]. As he tightened the engine down he blocked off the fuel flow. Not quite as obvious as the gas tank but still we shouldn't of missed it.:I At least now he has a working tractor again and it still was alot less money than anything else.

If it was the vanguard my thought would have been a faulty fuel shut off solenoid. Thats what the problem was on the 16 in my 917. I also have another 16 Vertical shaft sitting here on the floor with the same scenario...
