Default 108 carb
My machine ain't running so good. It will start but will not run for long and definitely seems like a fuel issue. I can't quite get it up to full idle speed (and there's a trace of dark smoke) so as soon as I engage the mower deck it bogs down. I pulled the air filter and noticed gas droplets leaving the throat. Is it time for a rebuild, or are there things I can try short of that?

I would start with a carb rebuild.

Along with carb rebuild check the throttle shaft for play.

Sounds to me like it's sucking air someplace.

Sounds to me like it is too rich. Try turning the main jet in a quarter turn.

2 votes for carb rebuild

1 vote for too lean

1 vote for too rich

Sounds like a tie.


So.... who do you believe??


I'd rebuild the carb, just so you know what my opinion is.
But hey, I'm just another vote right??

I also vote for the rebuild, plus you might as well clean out the tank and lines while you are in there!

Well, that makes 3 for the carb rebuild. I've also become aware that I have no inline filter, and I probably should rectify that.

i don't run an inline filter on my 108, the tank has a screen in it and as long as everything is clean it shouldn't be an issue.

I ran my 108 for over 30 years with no inline filter. Rebuilt the carb every 7-10 years or so. Bi-weekly 2 acre grass cutting machine. Most of that was with non-ethanol fuel. Nowadays, ethanol fuel really messes with anything that's not in constant use.

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.
