I realize this is not a lawnmower but is motorized and has some relationship.
Now in addition to my Tomos TX-50, I have a new toy.
A co-worker gave me a kid's four wheeler the other day. I'm going to fix his Yamaha Bruin 350 in trade.
The bolt that holds the swing arm to the chassis broke and the rear shock is busted. In the meantime I have a bungee cord wrapped around the frame and luggage rack to keep the shock from coming apart if I the suspension decompresses.
Since it had been sitting for about 6 years in a storage building, the carburetor had to be thoroughly cleaned out. This was one of the worst carbs I had ever seen as far as being gunked up. The brass bits had turned green and had some buildup on them. There was some green funk that had settled in the bottom of the fuel bowl. Kerosene and a wire brush wouldn't remove it.
I put all the brass bits in my bead blaster including the float bowl to remove this green funk. I know when acid comes in contact with brass it will turn it green. I didn't know gasoline was acidic. Most of the time the inside of the carb turns a crusty white.
But what was really a pill was the main and idle jets. I tried soaking them in Outlaw fuel injection cleaner but nothing seemed to cut it. I tried compressed air, copper stranded wire as a pick. The only thing that seemed to work was hitting the main and idle jets with a propane torch. This black stuff started to ooze out after awhile. Eventually I was able to clean them out.
I figured if I couldn't get the carb cleaned up, I didn't have anything to lose. These carbs are not that expensive.
Anyone seen clogged jets this bad and where all the insides had turned green?
But I finally got it running:
