Hi,
Been searching in the forums for some time now but finally decided to join and need help from you guys!
This may be a long post but i need to describe thoroughly the situation i have.
I have a 42" Poulan Pro riding mower with the Briggs and Stratton 18.5 hp engine model 31P777 and Nikki carburetor
Last December i was out on vacation where a massive flood happened and covered completely the mower under water. Flood came and went and the mower sit there for about a week before i came back and discovered it covered in mud and other crap.
Before going into details of what i have done i have to tell that this mower has always been very difficult to start. When i try to crank it the starter moves the engine a litle bit and then stops, normally after trying for about 10 minutes i used to finally get it to turn the engine for enough revolutions for it to start
What i did was
1. Cleaned it a little bit to avoid more crap to fall into the engine
2. Took out the spark plug and drained the water that was inside the cylinder
3. Gave it a couple of cranks with the spark plug out to eject as much water as possible
4. Sprayed wd-40 inside the cylinder thru the spark plug hole and gave it a couple of more cranks
5. Drained the oil, filled it with fresh oil and changed the oil filter
6. Discarded old air filter
7. Put everything back together and tried to start it. I found my usual problem of the starter having a hard time trying to crank the engine but after tyring for some time it started!
8. I moved the mower closer to my garage, turned it off and decided that i would continue working on it later. Unfortunately after that it never started again, the starter will just barely turn the engine or not turn it at all and thats it.
At this point i tough that i had a bad starter and the flood had just made it worse than before so i was planning to buy a new one but after reading the forums i found out about the valve lash adjustment which i did today. I had to adjust it at tighter values than what the spec called for, i ended setting both valves at .003 and after that the starter was finally able to turn the engine properly!!
Unfortunately the mower will not start, it just keeps cranking and thats it. I took of the plug and while still connected to the plug wire i grounded it and crank it to check for spark and it does have spark.
Im really at lost here, any sugestions on what could i try.
The carburetor is still full of crap, perhaps it is screwed, i was thinking on either rebuilding it or buying a new one as i have no experience at all with carbs (i am from the fuel injection era :laughing:). However before i start trowing money at it would like to hear any recommendations on what else could i try.
thanks!
