Craftsman Model 917.270812 Won't Stay Running
I was able to mow the grass one time this season with my LT upon going to mow the next time the tractor started but then died. I have had to have this tractor worked on one time before for the same reason, basically flooding out, and the fellow told me that this engine
(Model #42E707-Type 2631-E1 19.5 HP) was known for getting gas in the oil and that when this happened to check to see if the oil smelled like gas and if it did to change it and it should work fine (Not this time) lol, This work was done about 7 years ago (I'm pretty sure they re-built the carb. or used a carb. kit or whatever it is you have to do to one). I was also told by a Sears tech. that this engine was one of the better engines made and would last me a lifetime if taken care of. We got this tractor in '97 or '98.
Let me share what I have done so far. Upon checking the air filter I noticed the foam pre-filter was quite dirty on one side so I replaced both the pre-filter and the paper cartridge. Changed the oil (a second time after flooding again) checked the fuel filter and when I released it from the line the gas that drained out was VERY dirty. I thought "Oh no I'll bet it's got a bunch of dirt in the carb"(There were a lot of fine particles that maybe got through the small screen in the filter). I replaced it with the newer type of filter with the paper cartridge inside. I had put the E3 lifetime spark plugs in the tractor but I bought new ones just in case. After letting it sit for nearly a whole day I tried to start it again and the same thing happened, it flooded out.
After Googling the problem I was led to this site and did some searching on the Lt model # I found one posting on this model #917.270812 which led me to another posting by "mownie" telling the person to remove the plug in the diagram (at the link he provided) to clean the main jet which I did with carb cleaner. Here is the link to the posting I found for this LT; http://forums2.gardenweb.com/forums/load/tractor/msg071232392085.html
The problem that this fellow posted is similar,upon pushing the choke in it will run for a few seconds but dies. Very frustrating! :-(
Each time it has flooded I have removed the air filter cover and the filter to find quite a bit of gas in the filter housing (same problem when it was worked on). I remove the plug at the main jet and captured the gas that comes out which was quite a bit. I do this to hopefully speed up the process of letting the excess gas evaporate. The last time I tried it I wanted to see if it would run at the lowest throttle setting. Started it and it ran longer at this setting but eventually flooded out again so I assumed because of this it is getting to much gas.
I have never worked on or rebuilt a carb. so I am a little leary of removing it and letting it soak in chem-dip as someone else has suggested.But I am willing to try if I can possibly fix it myself.(Oh, the carb. is missing one of the screws that attaches it to the manifold maybe dirt is getting in there?) Since it seems to be getting to much gas I am hoping I can make an adjustment or something to get it going.
Any help is very much appreciated. This is my first post here and it looks to be a very informative place with a lot of knowledgeable folks.
Sorry for such a long post but I wanted to give as much info. as possible the first time.
Thank You, victor2232
