Problems when running my Mower

[Lachiepower0402]

Yeah I know, but I also want to make it look good while I am working on the engine.

So with my question before, how can I tune the engine so the spark plug is not black after running the engine, I have already cleaned the carb once, but I might do it again because I think I missed a few spots.

Also I removed 3 cylinder head bolts from the engine accidentally thinking I need to take them off to remove the carb, What torque setting do I have to set them to when reinstalling them?

I still have to find a gasket for between the fuel tank and carb

I looked around online for a gasket for this mower for between the fuel tank and carb and I found this:

Diaphragm-Carburetor [391681] for Lawn Equipment | eReplacement Parts

It looks like the right one it is for model #92900 mine is model #92908

Could someone please tell me how to tune the carb for my mower and what torque setting to torque the cylinder head bolts to.

Thank you in advance

So far I have, cleaned the piston, cylinder head and valves of any carbon, cleaned the carb and washed out the fuel tank. I have yet to torque the cylinder head because my torque wrench is in a box and I'm moving.

What else can I do in the meantime?

So like I said in the last post, I have cleaned everything that I think needs cleaning. Reinstalled the head bolts and tried to run it. It runs but is still rough. Also I have noticed that the auto-choke is not working.

I have to open the choke with a screwdriver and leave it open while it is running otherwise to goes down to a low rpm. When I open the choke it jumps to a high RPM and is rough, then it dies after a while and won't start.

This also means that I can't use the new air filter that I bought for it.

What can I do?

By the way I am running 91 octane fuel is this ok for temporary fuel?

Get rid of them damn points, would be the first suggestion/. Pop on a good used electronic coil!!!!!

Or at least clean and "regap" your old points!!!!!!! Dang..... In the old days, that was a main part of a "tuneup"!!!!
