Main Jet Cleaning

Postby cub1947 » Tue Jul 06, 2004 8:47 am

After cleaning the entire fuel system and installing a filter , I still had a lean condition requiring slight choke to run well. Found that a #66 drill is the proper size to clean the main jet. Used in a pin vise it met slight resistance that proved to be deposits not touched by carb spray,removed only crud-no brass. Now it runs like a champ. As a side note, a Kohler fuel filter from TSC works very well with the gravity system.

cub1947,

Wouldn't a a good soaking in carb cleaner do the same thing. Just wondering as I am experiencing a similar problem having to run with choke slighly open.

Could you provide any more info on the Kohler fuel filter?

Thanks

Mike

The stuff in the jet was hard and seemed impervious to solvent. The filter is for Kohler CV engined garden tractors that use gravity feed from a remote tank and was purchased from TSC. Looks like the plastic Fram but is made for gravity feed.

i have found that any inline filter will work just fine as long as you install it in a vertical position
