Matt,
Glad you tried the gas first. That tells us a lot about the cause. 
Checking the heat range of the plugs would be a good idea, but 
personally, I don't think you'll gain much with colder plugs, but it's 
worth a try. 

I've seen Tetraethyl Lead substitute for sale at parts stores, and that 
might work every bit as well as high octane gas, but it also might cost 
as much or more. Check it out.
