Gasket is correct and the hole on the carbbase is free.
Took the whole carb apart yesterday and everything is good, as it was recently rebuilt.
I just spoke to my local carb source for parts - he thought I should go with a #49 jet.
Ordered one and will go from there.
I just like to keep driving the original 216 until my 261 is ready....
My first 216 experience. Having a good time, getting it to run smoothly again.
