2001 450 es project...neglected machine
I found this site a couple days ago, right after I brought a 2001 Foreman 450 ES home. There is so much good information on this website that I had to join. I feel like between this site and youtube I can probably fix just about anything on this ATV.
Notice that I brought A 450 ES home, and not MY 450 ES. This bike belongs to my mother-in-law, and had been used around her property for years, and was often borrowed by family members for hunting trips. However, about three years ago they purchased a side by side, and the poor 450 ES was pushed into the corner of the garage and forgotten about. I couldn't stand to see the bike rotting in the corner of the garage, and I knew it was not in running order, so I offered to take it home and get it running.
When I picked it up, as I expected the battery was done. I suspected the gas in the tank would be bad. So we jumped the bike and got it to crank strong but it would not start. A little starting fluid in the carb and it fired right up...and then died after about two seconds. We pushed it up the ramps into my truck and I headed home.
I am by no means a mechanic, however I have just enough knowledge and mechanical skills to be dangerous. I have worked on jet skis and dirt bikes in my youth so I know my way around these engines...a little bit.
By my deduction, it fired with starting fluid so the problem must have been fuel delivery. I checked the plug and there was plenty of spark. Then I noticed there was fuel pouring out of the overflow tube when the gas was turned on. I assumed at this point I had a stuck float.
That's when I found this site doing some google searching regarding the problem. After a couple days of reading posts I decided it was time to pull the carburetor and inspect it. This is where I ask for the help of the knowledgeable members of this forum.
I've attached some pictures showing what I found inside, a thick green film covering everything in the bowl. The jets have some serious corrosion on them. I suspect that someone put premix in the tank and this is the green film. What do you guys think? My plan is to clean and scrub everything down with carb cleaner, buy a rebuild kit with new jets and gasket, drain and flush the tank, and finish off with all new fuel lines.
I am a newbie with ATVs so any advice and/or criticism is appreciated.
