So I have a Grande with a 13.13, redfilter, 12.5mm intake, and Leo Vinci HM. Plug chops have looked good for months, so mixture is right. The thing is, when I start it, I typically engage the choke, start it, and itll run a couple seconds and die. Then I start it normally and everything is fine. If I start it without choke, it takes a while, as you would expect.
So here's my thinking: with the higher airflow due to the various upgrade parts, do I need to grind the choke lever slightly to allow a tad more air while the choke is on? Has anyone done this or experienced the same thing?
