I just cleaned carb out on my old craftsman, It's has to be a 2000's model? It's never run better, but the idle just now runs too low! If i go into went grass it really bogs down! I tightened up the screw with the spring on the side (circled) and it runs better, but still low. It i manually open up the carb or whatever that thing is beside the screw (look at the arrow) with my thumb it really sounds good... So what did I do wrong when putting back together??

Have you tried the rod in the other hole?

I put the pin in the other hole and it seems to run at a much better rpm. But I had to thread that screw in all the way still...

What causes this??

Everything was put back the exact same way as before I took it apart...

He has the throttle rod in the correct hole on the throttle itself.

Perhaps he needs to adjust the governor.

He adjusted the idle but that won't necessarily help when bogging down.

The throttle linkage should also attach in the top hole in the governor arm, with the tension spring in the hole directly beneath it.

come again?

The governor arm sticks out of the motor behind the air filter. If you loosen the screw, you can adjust the governor.

I am bettering that you need to do that. I had to do it on another Craftsman mower (Tecumseh 6.75) recently after cleaning the carb.

One would be amazed over the improved running of the engine with a new air filter....

Read the section in this manual on how to adjust the governor.

If you are trying to mow into tall grass at idle, that is 1 problem, but doing anything with a totally clogged air filter is another, so you need to reconnect and clarify things a bit.

Fish I was wondering what you were talking about with the air filter. So I went back over the entire post and found nothing saying anything about the air filter until I looked at the picture again. Holy crap that thing is not an air filter anymore. No way air is getting through that thing. Good call Fish.

Well it may not be his whole problem, but it should run better with a new filter, just look for the simplest/cheapest things first.

Yep my Mom used to say "If your car does not start. Check the battery. Don't change the engine"

Any update?

As to my update I am going to bend that first piece in hopes that it will gain some rpms to the motor, which I will try this weekend. I also moved the position of that of that rod to the second hole, I posted this last weekend and it gave me alright performance... I will try the bend this weekend to let you know after this damn rain!!!!!

On another note, This is a David Rock video isn't it?

Well, just for fun...... Start it with no air filter.

I suggested that you adjust the governor arm. Leave the arm in the correct hole for the throttle plate! Moving it around will not really solve the problem at all. It should be in one specific hole.
