Sears snowblower spark plug replacement

Sorry another new guy lost on how to start a thread and in what forum. Have a model 536.881800 - 8 HP snowblower that the instructions don't seem to help me. 1. Remove the choke control know see fig 21 which just points to the knob. I don't understand if it just pulls up or twists out and I don't want to apply too much pressure and break the plastic part off. Watched you tube and couldn't find anything close that was helpful. Sorry if this isn't the right way to do this but would appreciate any guidance on how to get help from the DIY. Thanks everyone.

Welcome to the forums.

I moved your question into its own thread for you. Hang tight and someone should know what to do for you.

Referring to the manual available at searspartsdirect.com, which is presumably the same as the one you have, on page 15, under "how to start a cold engine", the instructions say "rotate choke knob". But, on page 22, how to remove the snow hood" under "service and adjustment", it mentions that the choke will not work if the knob is not properly installed. So my guess is that it does rotate, but is not installed correctly. Maybe remove it, carefully so you don't break anything, and see if it needs to be reoriented.

Here are manuals for your engine specific.

It is not real clear how it comes off but does mention needing to remove the snow hood.
The diagram is on page 19 fig 9, instructions on page 4 of this Manual Looks to me like it is just a friction snap on type of fitting.

Choke Knob

Should be friction fit and just lift straight up.

To better explain, I have the manual, I've reviewed all you tube video's, the snowblower works, I've operated it around 100 hrs and it's beginning to sputter a bit so I want to change the spark plug on it. model 536.881800 requires you to remove a cover to get to the spark plug by 1st removing the choke control knob. I need help in understanding if you just turn the choke control knob counter clockwise or pull it off, it's plastic and i don't want to break it off. thanks.

Just pull it off, then push to snap back on during re assembly it appears to me.

Which manual do you have? If it is one supplied by Sears/Craftsman, it will not be as complete as the one from Briggs for you specific engine.

If you try the first link it works for me and has the entire briggs list of manuals, I am referencing the second one in the list noworkynvm

Apparently cannot link directly to a .pdf, sorry. Here is the url for the briggs list of manuals.

Hi all good, was able to access by pulling straight up on the choke control. The plug looked good, pretty sure the carb needs to be cleaned. On to researching my next project, hoping there's a gas additive that good will help clean the carb. Thanks for your help.
