Motor Won't Open Up ?
 

1994 Z212 5.7L , screwed up this past winter didn't get it winterized fast enough, long story short tore down the motor and put 2 new heads on it for my screw up, never do that again that was work. Except I get it all back together and for some reason I am having a Hard time getting the motor to open up very quickly in the water. I can give it full throttle and it wil start going then after about 10-20 seconds or so it wll open up and run like heck, I also have been having problems it seems with the electric choke staying closed when it should be open any ideas if these two things are related? I can't seem to get my mind wrapped around it and it's driving me crazy.
Thanks

Hmm, sure seems like those two things could be related.
How's it act when it's not under a load?

Thats how it acts when it's under a load (in the water) or pulling, runs good give it full throttle, takes off then about 20 seconds later sounds like I gave it more throttle and opens up. I was thinking it was the secondary in the carb but after the problems I am noticing with the choke staying closed I am leaning towards carb problems not timing or anything else.
