Starting cleaning up and getting my Big Six up to snuff. I took off shroud and gas tank to clean them up. Have two things I can use your advice with:

I see two carbs listed. One is auto choke. I assume with bulb primer this is not auto choke but want to make sure in case I order new carb.



And I think my son bent the speed linkage when he folded handle to put it aware last year. Can anyone tell from looking at these?

Finished fixing up the Big Six. New carb from Reparclinic.com and it starts on first pull. Here's my spruced up Ninja and a look at results on lawn:

Main fan belt is quite loose. It looks like there's an auto tension-er but not sure it's working. Should I just get new belt?

And tires don't have much traction. Any source for cost efective replacements? Actually I'd like to go bigger to get more height on cut.

By main fan belt do u mean the belt that goes around the shaft and turns the flat disc? Yes it could be worn and replacing wouldn't be a bad idea. I'm not sure if the tensioner system on yours is the same as my older ones but if so there's a spring that attaches to the tensioner and goes to the deck. That's an easy cheap replacement to fix lack-of-tension. As for bigger wheels, I'm guessing u have 8" front and 10" rear. A new set isn't exactly cheap, about $80 for steel. I don't think they come any bigger but could u add some height by setting the height adjusters past the highest setting? They would be basically one notch beyond that highest setting. Just an idea.

Yes that's the belt. I noticed it flopping while running. And if I press on it it is quite loose. I'll take video tomorrow and post.

Have to look at going past highest position. That would be easy fix!

THANKS!

You can see belt flapping around since its so loose. It works but if not too much trouble replacing I'll put on new one. I was thinking the lower horizontal disk was tensioner but it appears its just a guide as it's fixed. Or is it adjustable to take up slack?

The thought of going past the highest setting actually just occurred to me recently. Glad that helped!

So there isn't a spring connecting that lower, smaller idler pulley to the deck? If it is fixed then I'm not sure how tension is applied, I'm only familiar with the older ones.
