Setting a moped's timing could mean the difference between blasting your max to running sloppy or burning a hole in your piston. For anyone who doesn't understand, you need to set when your spark fires as the piston is moving forward and nearly reaches the top. You want the spark to fire JUST before it reaches top dead center when the compression is becoming the greatest. I normally set my Polini at 1.25mm and then set my Parlini kit at 1.35mm. I bought a Buzzetti timing tool from Treats, and it worked decent. There was still a little play in the tolerance of the threading and I knew it wasn't perfect... So I went to Harbor Freight and, using some coupons, I walked out with the Pittsburgh digital dial indicator for less than $25. It has US measurements and metric. I ONLY do metric when it comes to mopeds and it was accurate down to 0.01mm. So one hundredth of a millimeter. Or if you prefer inches, 0.00039 inch. Pretty darn accurate.
So let's begin:
Insert the plug into the other and then connect them. I wish I had a welder, but instead I rely on JB Weld when applicable and can pass for my perfectionism. It did the trick nicely. Maybe I should invest in a welder or at least keep an eye open for one on Craigslist. Anyway, you want to make sure that it is a very straight fit, so find something that is 3/8" to slide them on... in my case, an old junk 3/8 drill bit. Let it dry up and remove the jig or old drill bit.
Still looking at a weak disturbance tonight into tomorrow with a light accumulation of snow possible for much of Ohio. Should be less than an inch for most of us. Wednesday we dry out and another weak system Thursday that could bring a rain/snow mix. Friday a little rain is possible with yet another weak system. Our temperatures warm up a little heading into the end of the week and the next system after that will roll in sometime late Sunday into early Monday... which, again, looks pretty weak with light rain. You could take all of the precip from the upcoming systems and it wouldn't amount to the rain we say Monday. I would just keep the umbrella handy. I will be heading to West Virginia in the morning for work the next few days. I will probably be blogging from the road, so be sure to check back in for all the fun. Have a good one!
