Are you referring to the length of the jet itself, or the length of the tube between the jet and the carb where the needle sits?
How is this length adjusted?

How is this length adjusted?
So you drilled a 63.5 jet
It is not possible to drill a 68 jet using stock drill bits.
#70 bit is stock jet size at 71.
Are you doing the plug chop with a new plug?
#72 0.025 0.635 63.5
#71 0.026 0.6604 66.04
#70 0.028 0.7112 71.12

the length of the hole you drill - if you fill the dimple on the jet with solder, then drill that, you have both the length of the original passage plus the length of the hole in the solder - worst case, you also have solder inside the body of the jet making it longer on that side too
in some cases, if you drill exactly the size it originally was, just the extra length leans it out a bit
Yes, according to my drill bit set, the stock was a #70 = .028
I soldered and drilled to a #72 = .025
I did not put a new plug in to do the chop set. I can do that. Never thought that would make a difference.
What should I set the gap at?
This is off topic, I know. But I did a search for "hub" and found nothing. You fellas here seem to know what your doing so....
I rode my bike about an hour yesterday. Most of the time at half throttle. Got home and smelled something burning. Not bad, but I smelled it. It was coming from rear wheel hub. I stuck my fingers through the spokes and touched the hub. It was VERY hot.
Do I need to disassemble and pack the bearings? Do I need a new wheel?
This is on an Onyx 29ner from Wal-Mart. It has maybe 5 hours run time.... Maybe 10 hours

Thanks for the reply. It has coaster brakes. It also has caliper brakes on front. I use them together. Was going to put caliper brakes on bale but there was some reason that made it difficult and I nixed it. I can lol at that again.
So it's the brakes causing the heat?

Let me rephrase that question. Is it the use of the breaks that causes the heat, or is it something about having coaster brakes on a wheel like this that produces heat even when the brakes are not in use?
on a coaster brake bike, there is only one gear which limits speed to 15mph or less
brakes and wheel bearings were only built for that speed - if brake is never used and bearings are well greased often (assuming one doesn't throw the bearing cap away when fitting sprocket) the wheel should last fairly well
even on geared bikes, things like freewheel pawls wear out rather quickly due to speeds in excess of designer's expectations

Now I am learning 
given the bike have, would you suggest that I buy a new wheel? If so which one?
Or should is there something I can change on this hub to improve its longevity? Remove coaster brake?
Thanks again
