Just a little over a year ago, our house was hit by the 2019 Memorial Day Tornado. Thankfully, it mostly damaged the roof and siding, and the electric was out for most of a week, but everyone was safe. After cleaning our huge chest freezer out in the garage, we never got back around to plugging it back in. Eventually, I sold it a couple of months ago to free up some space in the garage.
A couple of weeks ago, I saw a Craigslist posting for a black Solex 3800 moped, "runs and drives ok - $300". I had never seen a moped with the engine up there by the handlebars, and was intrigued. My oldest son and I went up to take a look, watched the guy start it up and whiz up and down his driveway and the road a bit, then traded the tornado/freezer money for the motorbike.
We got it back home, then we took turns starting it up and riding it a bit. Initially, it seemed to alternate between running rather slowly for about 20 seconds to running quite well for about 20 seconds, and then it would sometimes die. Figuring that this fuel might be years old, I dumped out the old fuel. (heck, the guy might have had alcohol gas in there) I replaced that with alcohol free gasoline, mixed with Sta-Mix Smokeless semi-synthetic 2 stroke oil I picked up at Tractor Supply.
My son took it for a spin of about 3/4 mile last night. I took it out for about a mile and a half this morning. It definitely seems to run a bit more even than before, but I noticed that most of the time it still seems a bit "bogged down", and sluggish. Still, it was fun to take it out on the road.
Now that I've replaced the gasoline, I'd like to replace the spark plug. However, I have found various websites listing about a dozen different spark plugs as a best choice for this Solex 3800. I'm not sure what to order! If you have any suggestions for that, I'm all ears. Thanks!
