I was getting ready to jump in and start some maintenance on a unit not used in a while.
 
I planned to let some sea foam soak in the fuel system by priming it and letting it sit overnight. 
 
Joke was on me. When I primed it i noticed fuel dripping from the other side of the motor. 
 
Now I have to start taking stuff apart to investigate and see if it is just a varnish plug or a complete rebuilt or replacement is needed.
 
First I need a diagram of this engine. I think I found the oil drainage pipe but I really need an engine manual.
 
Any Ideas?
 
TIA
 
 

A full ENGINE model # would help...
 
 
.

Of course. I forgot.
i really don’t want to break anything on this engine. It is in excellent condition except that is has been cranked in a few years. The choke knob just pops off?
 I have a picture of label….
model: HMSK 105 159908B
engine famdamily: 1TPXS.3582BF
displacement 358.         DOM: 1277E
 i forgot to explain the picture, there is green @$&@$# coming out of the carb.
TIA

Here's the parts diagram for your engine:

Part #380 are the options for your carb.  It does not show a break down of the carb however
it's a very basic carberator..

Scott thanks, the link goes no where.

Link works for me

Green looks like algae from water, carb needs cleaning

I didn't see the green in the pic, but I do now Mike....
 
+1, there's something going on in that carb...
 
Here's what the inside of the carb should look like (after a Sonic cleaning):
 
 
 
 

hey Man THANKS, the link wouldn't work on my new IPAD pro, but worked on my MBP. 
I appreciate it.
 

i have rebuilt a few carbs this year: a poulan chainsaw, a wood chipper with a Kohler engine, craftsman string trimmer, and now looks like this 10hp tecumseh engine. It looks more complicated than the others I have done this year. More linkages and so on.  But it needs to be done. This diagram will help me know this engine!
