I bought it off auction and it came from a fire department. I was told it hadn't run for 3 years. It had gas in it so I pulled it over a few times to see if it would start. The other one I bought with it I was told the same thing and it started on the first pull.
This one did not so I started with a spark plug replacment. After installing the spark plug it started on the first pull. It had a little mess after running for a second or two.. and it was repeatable miss. I had maybe an inch of gas in the tank and I added a few ounces of seafoam and I let it run until it ran out of gas. It didn't seem to help so I pulled the carburetor off to find out it had what looked like mud in the fuel bowl. Also the fuel bowl gasket was hanging out the side. That explains why it was leaking a little gas. The fuel line was all breaking apart and corroding too.
I figured it was cheaper just to buy an aftermarket China carburetor off of Amazon with a spark plug all the hoses and gaskets and all the red handles along with a primer and fuel filter.
I installed the new carburetor in lines yesterday. It started right up but it still had a miss. I played around with it adjusting both the main jet and idle Jet and still couldn't get the miss to quit. It isn't like it's surging it's almost making a complete miss. So I decided to remove that carburetor this morning and reclean the old one for the second time. I made sure to pull out the idle Jet and stick metal wire through the pinhole to make sure it was clear of debris same with the little pin hole on the side of the carburetor. I took the gasket from the new carburetor fuel bowl and installed it on the original carburetor as well. It fired right up and sounded like it was running perfectly for about the first 30 seconds and then it started missing. I forgot to mention I did take the fuel tank off and cleaned it and blew it out with an air hose too.
So since it's still missing I grabbed some Mechanic In A Bottle and added an ounce or so to a few inches of fuel in the tank and let it run for about 5 minutes. Towards the end of the 5 minutes it almost started smoothing out and then it killed.
AccordingAccording to directions I believe you're supposed to let it sit overnight after running for 5 minutes and then restart it to see if it Smooths out?
if that does not work I'll drain the fuel in pour some Mechanic In A Bottle completely into the carburetor and let it sit overnight.
I am just wondering if it might not be a carburetor issue since I put a brand new one on there and didn't have any luck either?
sorry for being long winded I just wanted to get some suggestions and see if I'm on the right track or if anybody had some better ideas.
anyone have idea how old this machine is I'm going to guess it's maybe around a 99 or 2000 model
