Carburetor Replacement – 10hp Briggs & Stratton [PART 1]

Part 1 of 2!

Today we’ll be replacing a carburetor on a 10hp Briggs and Stratton engine.

Model: 256707-0109-01

The reason I’ll be replacing the carb, instead of rebuilding it with a kit, is because the old carburetor is in rough shape & it will be easier & quicker for me to replace it.

OEM Carb: 491604 (Discontinued)

Aftermartker Carb: 491590 ($78 CDN)

In Part 1, we focus on modifying the Aftermarket carb to work on our application.

In Part 2, we’ll be modifying the air box & finishing the installation.

  3. Do you know the thread size on fuel shut off inlet valve?
    Is that fuel pressure tool something you can just buy?
    Thanks for vid, I am replacing same carb/same 10hp day before you uploaded this vid. Glad u found the model # on replacement. I am seeing them for <$30 eBay. Canada must be more expensive…

  4. I always enjoy watching your videos. You explain things in a way that most people can understand. I enjoy watching so thanks for posting.

  5. Nice save on this machine by swapping out a discontinued carb with an alternate carb and a few simple alterations to make it fit. Your customer must be extremely pleased. Keep up the great videos i am sure many will appreciate this one with others that have scrapped their machines being very unhappy to find out they could have done what you just did.

  6. Excellent as usual. I have a Niki carb on a 1450 series briggs 305ccย that won't run right even after I drilled out the pilot jet. I have done several before with some good results.I have a small engine shop and hate the Niki carbs. Do you know of another make carb that will fit in the place of the Niki? I thought maybe a Walbro might fit? Thanks for the video's.
