May I ask for help? I purchased a new Honda EU3000IU generator about two years ago and fortunately have had little reason to use the generator until the snow storm that left 30 inches in my area last week. In preparation for the event, I took out the generator and prepped it on the chance we lost power. Unfortunately, things didn't go well. Although I had drained the fuel tank last year, I had not emptied the carburetor by loosening the drain screw. When I added fresh gas to the tank and attempted to start the generator, it was slow to start and although it did start, it would only remain on for as long as one minute. In searching the internet for alternatives, I stumbled across a post that suggested a fuel additive "Mechanic in a Bottle" gas treatment, which did help slightly but still the generator would not run past a minute and a half. Again, looking for fixes, I cleaned out the carburetor in accordance with directions on YouTube ([url]https://www.youtube.com/watch?v=QhNy2lfJCEE[/url]). The cleaning went well, but did not improve the performance of the generator. The Main Nozzle and Jet were somewhat dirty but not blocked. The float chamber however was very varnished. When I restarted the generator after reassembly, the generator ran for just as long as before my cleaning it. What is unique about the problem however (before and after cleaning the carburetor) and may be a clue, is that the longer I leave the generator without attempting to restart it, the longer it will run. That is to say, the longest the generator will run is when I leave the generator over night without attempting to restart it (it will run for 1 1/2 minutes), if I don't attempt to restart it for a couple of hours - it will run for about 1 minute, if I don't attempt to restart it for an hour - it will run for 40 seconds, etc. It is as if the carburetor is fuel starved and needs to be replenished and the longer the machine is left without restarting, the longer it has the chance to replenish the supply of gas and the longer it will run. Although this makes sense conceptually, I'm stumped what to do with that thought. I do not believe the generator has a traditional gas filter, although that would have been my first place to look. Any advice? Thank you in advance.

Hi. I recently acquired a 1969 briggs and stratton engine model 130202 type 0283-01. While taking it appart i noticed cylinder scoring and some piston slap. When i run my fingernail over the scores i can feel them. I thought about boring out the cylinder to .10 oversize but the problem i am facing is that it is an aluminum bore. No sleve. A lot of sites say stuff like "boring an aluminum engine is a nightmare" and things like that. I wasnt sure what to do. In my opinion it is scored bad enough to just throw it back together. The rest of the engine is in really nice shape and would be really cool to get running again. Any thoughts?
