Default Onan P218

I have an onan p218 that I cannot get running right. It sat in a barn for awhile so I drained gas, put new fuel lines and fuel filter. Rebuilt Nikki carb and it still will only run on almost full choke. If I trickle gas in the carb when it is idling it will smooth out. This I would lead me to believe it is starving for gas. I read on another thread that the intake manifold is notorious for leaks. I guess I will take it back off and check it. Any other suggestions would be appreciated.
Thanks,
Earl

If you are certain that you have all the passages clean in the carb then you probably have a vacuum leak somewhere. If you can get it to run long enough spray carb cleaner or starting fluid around where you suspect a leak. Just be careful with the flammable liquids. Usually you can find a leak quick with this method.

The manifolds often leak at the seam where they are put together.. there are several threads on here where people have drilled out the rivets, separated them and resealed.

Good luck with it

Well, took off intake manifold today and checked for leaks. No leaks. Looked at carburetor again and realized I never took out slow idle jet to clean when I rebuilt the carb. Was completely plugged. Cleaned it out and put it back together and it purrs like a kitten. Thanks for all the suggestions and help.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
