I have a quick question, I have been running my +4 going on a gallon now. It is not completely broken in as the temps have not dropped and it is still a bit "sticky" up top without a plug in.

The issue I am having is that it is dying out at the end of the main straight. The settings are the same on the needles and it is running 225-235, the only thing that I have changed is to replace the stock Novarossi #5 plug with a 099. I am about to try the 077 to see if it is any better. When I do an idle test about 2" from the carb it dies after about 4 seconds.

How does the temp of the #5 compare to the 099 or 077? Would you recommend going leaner ar richer on the low end? It nearly seems like it is loading up, but I don't want to go too lean on the bottom either. Thanks
