Bad news...not a good sign. Yes it might tighten, but don't over do it. If a factory plug change to a NGK or the like. If this doesn't do it, and before I bought a new head, I go to Home Depot or the like with your plug and see if they have a COPPER or BRASS washer. Slide over the threads and install. Spark plug torque specifications in GOOD aluminum heads are from 132 to 192 INCH POUNDS
May I ask, do you really live in Pomona???
As I said earlier, that's a HUGE city area!!!
There should have been a hundred places within 10 minutes of your home that sells the proper plug... and maybe half of those could have given you advice about your motor!
IMO you would benefit greatly from some direct inter-action with some other people interested in small engines.
What oil are you using in your mix and what ratio???
It will be 101F here today... probably close to that where u are...would be really good to get this machine running and get into the wind!
Good luck

And don't depend on the BIG box stores like Auto Zone, Advance, O'Rileys...all they know is how to look up something in a computer, most are as stupid as elephant dung about engines.
Make car
year car
model
engine in car 4, 6, 8
automatic/standard
2 wheel or 4 wheel one keyboard stroke at a time. If it wasn't on a computer they would be lost.
I grew up before computers and we looked it up in a catalog. Most mom and pop stores knew something about vehicles back then.
Catch my drift
Ron, you are completely right. When I worked in a auto parts store we looked everything up in books, you had to know about mechanics or you would not keep that job very long.
