engine filling crank case with oil

[koltynsherman]

hi i have an 11hp greyhound and after a few rides it puts all the gas into the crankcase. im only 15 i dont have the money to bring it to a mechanic. but i do have my dad to help but he cant figure out why its doing it. we took the carb off and cleaned it. but after a little bit it did it again. my dad said if it does that again and i ride it without knowing my engine could blow. i just need help on what to do thank you

maybe the rings are worn? im not sure, but that is really strange.

do you have a warranty with harbor freight? they come with (i think) a 3 month warranty free. so if you didnt buy one on top of the 3 months, bring it back asap....

how did you know there was gas in the crankcase? you checked the oil and it seemed.. strange colored?

 

[koltynsherman]

well i bought the cart off of craigslist and the engine was like 6 months old the guy said.and i check the oil almost everytime before i ride it but one day it was so hard to start my electric start couldnt even turn over the engine i had to pull the pull start with some force to get it to turn then it started after that i remembered to check the oil so i shut it off and unscrewed the oil cap and oil came gushing out but it was just oil it was like half oil half gas im good with engines i can tear one all the way apart and put it back together but im not good with carb functions i was thinking it could be somthing wrong with the needle and seat but im not sure.

Float and/or needle should be looked at first.
Float may not be floating causing bowl to overflow and dumping into crankcase.

My honda motor did this a few times, cleaned the carb and didnt have a problem since... well atleast not that problem...

 

[Doc Sprocket]

Here's a question- when you put the kart away for the night, do you shut the fuel valve at the carb off, or leave it on?

My money's with Russ. Either the needle's not seating, or the float is shot.

It's always good policy to shut the fuel valve off when not is use. And certainly something you'd want to do while trying to fix the problem. If your oild is being diluted with fuel, you might just as well pour some sand in the crankcase for al the damage potential it has.

Had a Briggs that did that same thing, the float would stick on the side of the float bowl. The float had a little piece of flash on the side. When it ran compleatly out of gas, it would wedge itself in the open position.

 

[Bluethunder3320]

i should probably check my 10hp tecumseh then.... once it flooded and locked up solid... once i drained it all out of the cyl, it ran, never thought it might be in the crank case all this time.

maybe its time to put that new briggs in my tractor lol.

 

[Doc Sprocket]

For sure. If the cylinder had enough gas in it to hydro-lock, you can bet your next paycheck it was seeping past the rings.

 

[Bluethunder3320]

so what can happen? it ignite? and crank case goes boom?

 

[Doc Sprocket]

I'd be more worried about the LACK of lubrication- the gas will thin the oil right out.

 

[koltynsherman]

okay is there any places that sell parts for these engines. thanks

 

[Bluethunder3320]

youll have to get honda (gx390?) replacements

 

[Doc Sprocket]

11hp clone? That's the GX340 parts you're after. Don't order anything until you figure out what it truly needs.
(GX390 is the 13hp)

okay im thinkin about just sellin that engine so i can maybe get a atv engine so i can have gears for climbin hills.also im lookin at this other cart for $100 that has true independent rear and independent front suspension has no motor but its custom and its built really well ill put up a pic tell me what you guys think thanks

Mounting an atv would require some welding and fabrication work. Where have you found a kart like that for $100?

 

[koltynsherman]

engine

im thinkin about sellin that engine and just getting an atv engine im lookin at another cart for $100 that has all independent suspension its all custom tell me if you guys think its a good deal.

Hard to tell since the pics are tiny.

 

[Doc Sprocket]

Man, you couldn't get a lug nut off that thing around here for $100- I'd be all over that...

 

[koltynsherman]

okay thanks i just need about $30 more and see if my dad will take me to get it but im waiting for the guy to send me better pics he said it was setup for a 10hp briggs with a gear reduction but he said it would take nothing to put a motorcycle engine in it i dont want a motorcycle engine i want an atv engine so i can go in the mud and up hills i dont want to kill myself i want to go fast but not as fast as a motorcycle engine would go lol
