I'm not even sure how that's starting at all. At a guess you've got enough coke on the throttle butterfly that the engine can barely idle. The heel-n-toe is keeping it alive.
Good try Mako but not true. The ST200 throttle body and lower butterflies are pretty much spotless. Running ST200 upper inlet, throttle body, tubular exhaust manifold with out that horrible "put exhaust fumes back in the top of the engine" link, Got the main Cat in and if I remember rightly a blue flame twin tail pipe zorst system. Most if not all bought from your good selves on this forum.
Needs barely any heel and toe, within half a mile she'll tick over fine. And with regard to "well I'm sure you wouldn't actually drive it like that " Sure am, done around 3 or 4k in the last few months and enjoyed pretty much every second. Even got the average fuel consumption up to 34 !
Yeah, that'll be the lower roll restrictors I should think. They can get pretty bad before you really notice them.
That's what I would expect. Assuming the rest of the inlet tract is in order, I would expect it to start, sputter, and probably stall.
Well, I'm sure you wouldn't actually drive it like that.
