I have a Troy Bilt lawn vac and chipper with a Briggs & Stratton 124T02-0510B1. Originally I had a problem with an oil leak on the carburetor side of the engine. I thought it may have been a leak at the crankshaft seal but it was not. When I took everything apart and went to remove the air cleaner housing I noticed that the intake manifold was loose. I got a full turn on each bolt to tighten the intake. That stopped the oil leak and I was hoping that would stop the smoke and hard start issue but it did not. I also inspected the breather system and everything is clear. When I am shutting down the engine to empty the bag blue smoke comes out of the muffler. While the engine is running there is no smoke and the Engine is strong. Also after the engine has been running for approx. a half hour, if I stop it to empty the bag it is very difficult to start. After it sits for about 10 minutes it will start up..
Any help would be greatly appreciated
