I haven't done much tweaking in the past so this might be relatively easy however I am running into issues. This is what I do:
Stop MySQL
Edit my.cnf (changing innodb_log_file_size)
Remove ib_logfile0/1
Start MySQL
Starts fine however all InnoDB tables have the .frm file is invalid error, the status shows InnoDB engine is disabled so I obviously go back, remove the change and everything works again.
I was able to change every other variable I've tried but I can't seem to find out why InnoDB fails to start even after removing the log files. Am I missing something?
Thanks.
Edit: Pasting of the log below - looks like it still seems to find the log file even though they are not there?
Shutdown:

Its just a spam of the same error until I correct it
When it did start after it recreated the log files so it must be looking in the same spot I am.
