Hello- I am new to CTLs as well as this forum. I recently bought a used Mustang mtl 16 (a twin to a Takeuchi tl 130) from a private seller. It has 1150 hrs on it and seems to run well. The tracks needed to be replaced and the seller (who had a shop) agreed to replace the tracks and sprockets. He replaced them with new parts. Now that I got it home and ran it about 3 hours I have noticed that on the left track there is one spot (drive hole on the track) that does not align with with the cog on the sprocket. This causes the cog to raise the track until the cog "pops" into place. I can not see any irregular part of the metal cleat that is causing this problem. I also tried adjusting the tension (both up and down) but the problem continues. Is this a problem that that will go away as the parts "wear in", or do I need to do something about it now? I certainly will appreciate any ideas from you folks who know alot more about this than I do. Thanks.
