Could get it to start but if I opened the throttle slowley it would die and was hard to get started.
I found before the valve was fixed that if you would flat foot the throttle it would take off but ran like junk untill warm and still ran like junk.
I hope this will help.

Funny, I seem to have a similar issue.
Hard to start, and can't open the throttle more than a little until it warms up.
Idle gets progressively faster as it warms up.
I assume it is a leaky/cracked intake, but the valve issue could come into play.
