91 520H hard to start if sits

Recommended Posts

If I start it regularly it fires up easy. If it sits 2 weeks , it is very difficult to start? Weak spark? Also I have a bit of an emergency. The tube or exhaust besides the carburetor.  I think I dropped the wing nut down that whole. The fly wheel is in there too. So  I haven't turned it over since. How difficult is it to remove that housing so I can retrieve the wing nut,

If just sitting fuel drops down the line and it takes some effort for pump to pull it back up to carburetor. You can install a check valve right before pump to prevent that . I have done it and it works great. Leaving tractor at an incline with front end down also helps since that tank is located lower than carburetor. Gravity is against that system.

Shroud is not hard to remove but it is a labor intense affair. Just be patient and make sure you find all bolts to remove it. There are a couple underneath shroud in not a too obvious location.

And if you've got the tins off it would be a good time to clean out all the cooling fins.  Gun barrel brushes work well for this task.

Good point. I actually also after every mowing, religiously blow compressed air through out entire engine to remove any accumulated clippings or dust. The same thing around hydro and transmission under seat.Takes only a minute but keeps all air passages clear.

I do the same.  Not always with my 'air pistol' if I'm too lazy to drag the hose and turn on the compressor, but I always have my hand held blower close by.

 

I was amazed the last time I had the tins off the Kohler how much crap had accumulated IN SPITE OF cleaning/blowing after each use.
