Re: bad experiences so far :(
camlifter is talking about where the carburetor attaches to the intake manifold, so yeah the engine. I think it may very well be an air leak also. Luckily, air leaks are usually pretty easy to find. Just hold a lit cigarette close to the area you think air may be leaking while the engine is running. I quit smoking 6 months ago, or I'd come over and bring my tools and a cigarette, since I only live about 30-45 minutes from you. If you continue having problems, try uploading a video of the engine running to youtube, so some of these experts around here can hear it running.
