14HP B&S No Fuel Flow
Comments (15)Per my post above, the fuel pump is a part of the carb as is typical of this series of engine. I do not know of any way you can test the pump. Either it fills the carb bowl or it doesn't. What happens if you remove the gas cap, place your lips against the opening and blow hard? will the engine remain running if you do this? (don't inhale the fumes) I would be inclined to say you messed up when you rebuilt the fuel pump but you have tried another carb with same results. Did you get a diagram with the rebuild kit showing the arrangement of the two tinny, tinny, springs in the pump? Are you sure they are installed in proper position. AND the impulse, vacuum line from the engine block connects to the BOTTOM of the fuel pump with the gas line connecting to the SIDE of the fuel pump.

Comments (4)Thanks, bill! The local place where i buy my repair parts gave me the printout of it, later today, when i returned the kit they sold me, because it was wrong! We've had several days of rain here, but hopefully we'll get dried out tomorrow. And, maybe i can get my son to stop bringing in these orphans for repairs! His friend sold his property here near Pittsburgh, Pa., and is moving great piles of stuff to N. Carolina, where he has bought a farm! And, i keep getting more installments of stuff he doesn't want to take with him! This guy never took care of anything, just let it set outside in rain and snow and sun. The scrap man took away a fortune in old antique cars and trucks, and just plain scrap.Its no wonder everybody named him Bubba! So, thanks, any way: Rustyj...See MoreFuel Pump rebuild went bad; fuel in oil
Comments (9)Shucks, I accidentally hit submit . .................................................... Are you quite certain that the gas you are now discovering, was not already in the oil from before you undertook this rebuild? What may be damaged depends on how long the engine "ran" with contaminated and diluted oil. If the engine had been running with gas in the oil before the fuel pump work, I would expect the exhaust would have had a definite blue or blue-white color "smoke" in it. In which case, the most likely components to suffer damage would be the crankshaft rod journal and connecting rod, the piston and cylinder walls might have sustained some "scoring" or galling, but usually, the piston and cylinder of a 4 stroke engine, are "spared" in cases of gasoline contaminated oil in the crankcase. It usually requires that these engines be "run without any oil" before the piston and cylinder walls see damage (of course by that time, the crank and rod is usually "trashed" as well). Consider a 2 stroke engine escapes damage to the piston and cylinder with as little as 1 part oil to 50 parts gasoline. Also consider the the same amount of oil is sufficient to lube the crank main and rod journals in a 2 stroke engine, but ONLY DUE TO the 2 stroke design using ball or roller bearings in those 2 places. Plain bearings in the typical 4 stroke OPE engine will NOT survive long if run with diluted oil. If all the time this engine has actually run with gas in the oil, amounts to a mere 20 to 30 seconds, I believe all you have "suffered" is a solvent washing of the interior surfaces of the engine. Post engine numbers and let's see if we can find some illustrations of that carb. Maybe then we can retrace your steps during reassembly of the pump....See MoreHelp w/ Sizing Dual Fuel Heat Pump
Comments (5)I'd get a manual J just to see what you are dealing with. And ditto the high electric rate comment above. If Man J says you need 8 tons, then you know where you are at. But if the house stays cool in the summer and you are using NG, I'm not sure why it matters. If you are undersized on the heating size, that is fine. You have a good backup. This is the way I look at it (that doesn't mean it is right), you want to use HP, when it is above 30 degrees or so. Your 5 tons should do a good job down to that. If your backup was expensive, you'd want to HP down to 15 or so. Then, your undersized system would be a problem. But since you are just using HP for milder weather, you are fine - on the heating side. The HP gets less efficient as it gets colder regardless of size of unit. So you never really need the extra capacity, because you switch over to your good backup. As Tigerdunes said, if your electric rates are high, your backup might make sense at 40 degrees. In that case, your HP is doing very little. By my math, with my system, 35 degrees is my switch over at $.10 a KWH and $1 a therm. If you are $.15 a KWH and $1 a therm (therms are pretty constant nationally), then your switchover will be closer to 40 degrees....See Morewalt2002
