Vacuum Leak

I've had vacuum leaks in the recent past and the motor spit and sputtered just like it is now. I don't know for sure that that's the problem, but it just acted like a vacuum leak.

Now that the weather has improved, I'll get out and do some investigating today, see if I can find more clues as to what's wrong.

Google 904 TP adjustment? I'll do that and also look for any undone springs.

Thanks!
