I built a script to mine on my slow computer for fun. I have never found or submitted shares to the pool. My computer is 100% receiving work and hashing away.
First of all, i would recommend you to read
BITCOIN MINING INTRO & RULES OF THIS SUBFORUM - READ BEFORE POSTING.
TL/DR Summary:
- You CANNOT meaningfully mine bitcoin with your PC or laptop no matter how powerful it is.
Can anyone recommend a solo mining pool where I can adjust my difficulty and actually find shares while mining with 3 MHs?
Check

I have another question if I never submit a share to a pool and a miracle happens and I find a block do I not get the reward?
Yes, you don't get any reward when you never submit any share.
