Tom S Here is a tip use regular pump gas go back to 30 to 32 degrees total timing and it will run faster. 91 octane is more than you need . Higher octane burns slower that why you are running more timing than some. That goes for anyone else that is running more than normal timing. Drop down a grade of gas and lower your timing and you will be amazed how well it runs.
