We changed to 219 chain about a year ago and i feel like the tight and loose spots are worse on these than the 35 chains. What is the most common issue i should check into? Have a laser and got it pretty spot on.
I've noticed this motor I recently put on holes are a bit big for the studs, guess it could be twisted, I tried to loosen it and push it all to one side to get it straightWe run 219 as well .
Driver wear and out of round rears . The left and right should have very little effect on tight loose .
Junk motor mounts cause adjustment issues .
After it broke the chain Saturday I borrowed a used one I will order a new one219 has more links and more teeth to contact, so more chance of bad teeth (or pinched links) to cause issues.
In general, I'd say that 219 is the better way to go, but you've got to keep on top of your gears/chain.
If you ever throw a chain, likely both the chain and sprocket will be damaged.
Pitch the chain and you might get lucky with the sprocket just dressing it with a file.

Sprocket mount was bent after the mishap and we changed it but still have issues. Checked axle yesterday and its goodBent axle or sprocket mount?
What is space chain?Chain alignment?
Roll the rear wheels, the sprocket should be evenly spaced in the chain links. One side to the other is unacceptable.
Sprocket run out. I have found that sprocket holder's and sprockets have a fit tolerance. Sprockets tend to be a little bigger, sprocket holders tend to be a little smaller. This causes the sprocket, on occasion, to exhibit a little run out. If you're having a problem, as you turn the axle, the chain will increase tension and decrease tension as the axle turns. I use to turn the axle until I found the spot where the chain was the tightest. Now this is going to sound funny, but it worked. I would put a 2 x 4 against the back of the sprocket and hit it with a hammer. I know I know, but it worked.
Chain tension. Now Sprint karts may be a little different from dirt karts, but I would feel the tension on the chain. I would adjusted a little tight and feel. I can't really explain it, but if you adjust the motor mount adjuster, just a little at a time, at some point you will feel the chain kind of loosen up. Just past too tight. I know I know, but it worked.
Lasers and straight edges sound nice, but that sprocket has to run right in the middle of the chain. I always ran space chain. Chain is not a place where you want to save money. By the good stuff!!
