Craftsman 5/22 IS DRIVING ME CRAZY!

Bought it from the original owner in excellent shape but in poor running condition.

It ran ok and then would die and leak fuel.
Instead of taking the carb apart to check the needle and float I opted to buy a new aftermarket carb for $12.

I have had great success with them in the past.

I got the snowblower running which was hard to start.

When it runs it backfires...

Here are 2 videos...





Not but least I pulled the head to clean and check for carbon.

Now it runs even worse to an extent...HARD to start and won't run in full choke.




Here is a pic of the head removed before I cleaned it...

Did you check the valve clearance?
Do you maybe have an intake air leak?

I did not check for valve clearance since the engine had low use, look at the pic of the head off before cleaned it up a little.

How would I get air in? Fuel line looks new but I will replace it anyway.

Thanks for your response

Would a compression check reveal a valve clearance issue?

I'd say its running lean. The governor arm is moving a awful lot. They make an adjustable version of that carb, which is a better choice. See the ref thread below. Spray some carb cleaner around where the carb mounts, to check for a vacuum leak. Did you tighten the head down in the proper sequence and torque? The bolts are around 100in-Lbs

Thanks for your response
Maybe when you installed the new carb the intake gasket moved. Maybe the carb didn't get torqued down quite enough. When it's running spray some WD 40 around and see if the speed picks up.
