I got the starter replaced it sounds better when cranking and cranks faster but ...... The motor won't start no matter what I do. I have spark but when it's cranking the fuel seems to be pushing out of the carb to intake gasket almost like it's not being sucked in. Any ideas on why?

sounds like you may have flooded it pretty badly.

getting spark?

maybe you bumped a wire replacing the starter

If fuel is seeping anywhere then its probably flooded or requires a rebuild. Also if fuel is flooding out of the carb chances are you will need to do an oil change.

  I did a dry compression test here's the results (average)
#1 -70 psi
#2-0 psi
#3- went from 100 to 10 psi
#4-0 psi
#5-110 psi
#6-0 psi

And there seems to be a little bit of coolant on the transmission bell housing

Did you do the compression test with the throttle wide open? Those numbers seem extremely low.

Throttle needs to be wide open to do a compression test otherwise the results are null.

Are the numbers repeatable, cylinder-to-cylinder?  Cylinder 3 changing from 100 psi to 10 psi hints at a compression gauge malfunction.

What do you mean the high idle was on?  Did you start the engine to check compression?  Does the engine start now or do you mean the throttle was held slightly open while cranking?

No it was set so the throttle was open a little

lol.  You answered my question before I finished posting it.  Recheck the compression to make sure you don't have a pressure relief valve leaking on the gauge.

besides the gauge might be faulty, im not at all familiar with the I6 whats the common factor between the even cylinders vs the odd?
