Rough running gravely

I have a 5460 Gravely with a k241s. It starts immediately and runs well at an idle. When you run it at an higher idle it misses. I’ve put fresh gas in it, new fuel filter, cleaned the carb and spark plug, cleaned and adjusted the points, and replaced some bad wiring. My guess is it’s an electrical issue? I was thinking about replacing the condenser and points but wanted to ask you guys first! Any ideas? Thanks!

Update 2.0: turns out my gravely only needed new points and condenser. Runs like a champ now! So this forum was no help at all and probably will never visit it again. If your web search brings here for some reason, here’s what happened:

My gravely 5460 walk behind tractor ran great, but started to act up. It mostly ran terribly at a high idle. It kept missing and wanting to stall. After installing new points (which were set at .020) and condenser it started running better than ever. I bought them at isavetractors for about $16. I highly recommend the website. They’re very knowledgeable, with great parts at a reasonable price. I hope this helps you!
