You want something built, I'll build it for you. Need car worked on, got ya. Small engine, clueless.
Log splitter. Subaru sp170 6.0 engine. Can't get it to run. Replaced the complete carb, plug, air filter, fuel and oil. Will fire with starting fluid but dies immediately. Feel that leaves the ignition out. So here's where things a bit interesting. Pulled the oil plug to drain the oil and a good bit of water came out. Wasn't ran with water in it but sat outside so may have trickled in. Is the engine toast or am I missing something to try? Is there a way for the water to get in without the block being cracked? I have fuel flow past the carb. Feels like I have good compression but haven't put a gage on it to test. Oil is full so I don't think it would be a low oil shut off. Anything???

It’s a carb issue if it will run on starting fluid... it’s not getting fuel IMO
Pull fuel line off carb and make sure you getting a flow to cab... you can put gas in spray bottle and spray in carb like you doing with starting fluid.
When starts from spraying gas in carb keep spraying to keep it running to see if it will pick up the gas in carb!

It was doing the exact same thing so I completely replaced the carb with a brand new one. From the gasket on the block all the way through is all new. If I pull the screw at the bottom of the new carb, fuel drains out. Absolutely not arguing or disagreeing with you but if fuel is draining out of the bottom of the new carb, how would it be a carb issue and not getting fuel if the fuel is draining out of the bottom of the carb. Again not a small engine guy so not 100% sure what the carb is actually doing. |

This may help or make matters worse. duff used it so there may have been competency issues with the previous user. |

Try to keep it running with the start fluid or spraying gas in it .... it has to pick up the gas from bowl to run on its own! Getting the gas to carb is good but it has to mix in with the air being drawn in Choking it helps greatly also.... Pull spark plug and put thumb over hole and crank it to make sure you got good compression also |

The oil was low and very black so I added water to dilute it. Your welcome

So I shouldn't be overly concerned with the water in the oil? Again, unfortunately it did sit outside uncovered.

Honestly thinking about just pulling the engine and replacing. May just be less time consuming than trouble shooting. Thought about putting a hemi on it but then it would start rusting the next day. |

Could the new carb be defective? I've had that happen twice on small motors. It took a second carb to get them to run right.

Just because there is gas in the float bowl doesnt mean it is being drawn in thru the jet or port. If it runs with help, spark is good, and likely compression is ok since it runs. Positive it was water and not gas in the oil? The float/needle and seat could have stuck open and drained into the cylinder, leaking past the rings, into the crank case. Seen it a lot. A lot of engines have a gas shut off valve for this reason.

Go to harbor freight and get a $99 Chinese motor. Did that to mine about 8-9 years ago, starts on first pull.

Forget about the Hemi, put the Cummings on it and your problems will be solved.
If you are running the Subaru motor, you will need to check whether it's made in Lafayette or Gunma. If it's made in Lafayette, you should be OK running it on the ethanol blended fuels. If it's made in Gunma, you will have to special order in fuel that has ethanol made from rice. That may be your problem.

Update: I got it running finally. I'd like to thank everyone that commented for their help....I really would but it was worth the price I paid.😄😄 Did all you all suggested and nothing. The solution, and duff I'm really disappointed you didn't come up with this solution because of anyone you would be the one to suggest. I simply got fed up with it, took the cover off the carb and went to town on all the little screws that adjust something or another. No idea what they do or if they actually do anything but I felt like I was actually doing something turning em. Turned them this way and that and walla, it's up and running and splitting wood. If anyone needs small engine repair I'm hanging a shingle out front. |

Nobody thought of it because normally they would come preset where the engine would at least start, then adjust. |

I bet it was just out of gas or the toggle switch was still turned to off |
