Default Govener spring linkage kind of loose?
So I'm trying to tune up this K12hp engine. One thing I'm trying to get right is the throttle linkage. The spring is pretty darn loose when in idle. Is this normal? I've seem some pictures of this spring being replaced with one that has a long arm part to it. Is this some kind of upgrade that is worth investigating? Also, I'm trying to set the RPM range correctly. According to the manual 3600 is really the max I should have the top end speed set at. I've also read here that 3200 might even be preferred. So after setting this top speed and setting a good idle speed are you getting full range of through on the throttle lever up on the dashboard? When I set the throttle stop lever it seems like I cannot move the lever on the dash all the way to the top (max). Do you folks normally set the max through first with the throttle lever all the way to the top and work your way down using the idle speed screw on the carb to keep the idle from getting to low? I've tried that but then the spring gets really loose that connects the governor to the throttle cable.

Do the governor and throttle adjustments in order:

1.)Adjust governor linkage.
2.)Set low idle
3.)Set high idle

Yes, when idling the spring will be loose. You should be able to wiggle it with your finders.

I set the throttle lever so that min to max is in the center of the range. In other words, it may not go all the way up, or all the way down. You are safe to set the high idle at 3800 if you want.

Very helpful my friend! Thank you! Glad I can speed this up some because I was a little disappointed with the power I was getting. I think part of that is because of the terrible job I did setting the points gap. That's next HAHAHA

You don't set the points by gap, you set the timing. Come on, you hang out here all the time, you should know that.

Here's the link on how to: Static Timing

Correct, my miss type (at work and try to sneak these posts in when I can). I've actually used this guide but still have some questions. Will post tonight and also want to try this with my timing gun since I bought the silly thing and like to play with tools HAHAHA

Haha, thats funny. Why you ask? Because I too, do all my research at work, and go home and do the work at night. Its been working pretty good for me too. But my review is this week so we'll see how much the boss has noticed my "research" not being related to work.

Good luck on Timing, as it is something I need to do to mine as well. So, show me the way

Since I got my governor question answered and it looks like my questions are going to be around timing now I'm continuing this conversation on my timing thread

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.
