OK guys, you have help me out in the past and I got some more engines I need help with identifying.

Number 1, I have no idea...

Number 2-6 all seem to be K&B infant type engines, but they all have slight variations.
Not one of them is exactly like the other, some have larger cylinder heads some have
different intakes.
Like 2 and 5 originally looked the same, but 1 has a narrower venturi/ at the base.

HELP!

Thanks!!!!!!

# 1 .....O&R Midget .049

Smaller are the Infant .020 and the bigger ones are the Torpedo .035

#4 K&B 0.020 Infant.

#2, 4, & 5 I believe are all K&Bs.

They are all K&B's except for #1
