I have at Tecumseh 640086A carb on my Toro ccr powerlite snowblower (#38190). It was full of rusty water/old gas when I inherited it. I blew it out, cleaned it out with carb cleaner. I replaced the float, needle, seat, bowl gasket. It now seems to be a properly cleaned and functioning carb but I can't get it to start now. It also has a new spark plug with good looking spark.

When I prime it, shouldn't a fine mist spray out? Instead, a very thick stream of gas shoots out the main jet and it looks like it floods the engine immediately. I got it to start one time and it ran great. As soon as I shut if off and tried again, nothing. Just a really wet carb. I'm sure the float and needle seat work correctly as it used to leak gas constantly until I replaced those items. But how do you adjust it so it doesn't flood from the first pull?

Thanks for the help!

It sounds as if it's priming properly, it is not a mist, but a small stream of fuel pushed up the main jet that primes the engine. It may be that the float is set too high or the needle is not seating good.
