| my engine has been starting hard. and everytime i try to start it it gets harder to even turnover. its not the starter just rebuilt that. can someone help me figure out what is wrong with it i think it may be a valve.
i also,being stupid, forgot to check the oil so its been running bone dry
should i rebuild this engine or replace it | |

| My engine takes a minimum of 350 amps to start with a new starter. Try jumping it.

ya thats what i figured im replacing it now anyways i have a 14hp twin briggs that came off a 87 mongomery ward. im currently tearing the engine down and cleaning everything inside. but when i put it on i will need a new battery. i have a teeny one now and i dont thin that its enough for the 12.5 horse | |

| Bad alternator, Might have trained the battery Valves out of line, so the compression release isn't working. (If Applicable) Ground may not have a good connection Positive wire may not have a good connection
Im sure they are many more possibilities, but these are the only ones I though of so far....Instead of replacing it, I'd work on popping the head off and seeing if the cylinder walls are totaled, even if you have a spare engine. | |

| I think I have the same motor only mines the iron sleeve. I don't think I have much oil at all. ita blak and low, half off it is on the side of the motor bc the dipstic seal is broken | |
