I had a 1200 cub running had to adjust carb and clean it to get it going and it ran well except at low speed and then the engine stopped running. I looked and the carb got blown off. What could have caused this and do I need a new carb or does the whole engine need rebuilt and what can I expect to replace to get it going again???

You need a new carb.   Someone has cobbled that broken one back together in the past and it didn't [and won't] hold.

I don't think there is anything wrong with the motor.  it sorta looks like the carb was it already broken before it fell off  .  that's a 12 hp kohler isn't it?  you can find another from a sponsor here or as a last resort on epay

It looks like someone did weld it together at some point the entire exhaust of this cub is fabricated....

I bet this one couldn't go flying because it was attached by 2 bolts as well as a gas line which are all pretty heavy duty

Before investing $$$ in a new carb do a compression or better yet a leak-down test to be sure the lean condition the thing experienced didn't do any piston or valve issues..  JMHO..

I think at this point I might as well take the head off the engine and look at the head gasket and see what the wear is on the inside before I go spending $$$ on it. The clutch release rod was already fabricated by this guy just to get it moving to sell... Had to get help fabricating a better one that doesn't fall off.

Usually about this time someone suggests using JB weld to fix it. :rolling:

JB Weld fixes a lot of things and it holds too.  Just have to be reasonable on what you use it on and where..

I guess some folks have luck with it. Personally I have never been able to say it fixed anything.

I think the biggest problem using jb weld is not letting it set up & mixed in a good ratio. I have used it with success but it's not a miracle cure. Even the quick set stuff takes longer than instructed.
