Thanks for your post and here's an update:

I pick up an used engine locally and do a swap and it starts and ran fine along with a new coil and everything seems working even the remote start / kill switch so that plug is highly likely for another model with signal lights.

I suspected the previous owner couldn't figure out what's wrong (it's a faulty coil firing intermediately) and he remove the spark plug countless time and stripped the thread.

However, this used engine seems has worn rings (it smoke a little bit when its cold) but other than that it ran fine.

If I am fuzzy about the motor and wouldn't mind take it about what will you guys suspected?

Worn valve guides / seats or piston rings?

Also,it seems a little noisy (loose sound) when cold but after it warm up it pretty quite.

Thanks again!
