Struggles and dies at full throttle

[Keithoms]

I've started having this problem with my car. At idle to 3/4 speeds the car runs fine but whenever i hit full throttle, the car starts choking and cuts. Why is this? Also sometimes i have an erratic idle with random high revving and random cutouts. During these times the servo isnt moving.

I had this issue with one of my motors recently. Turned out to be too rich on the HSN and it was just choking itself at full throttle.

It sounds like it is very lean. That is what is causing the high idle. Try richening it 1/8th turn and let us know.

Happened to me today, it was a bit colder than the other burning hot days i ran it, turned out it was too lean.

If it bogs around 1/4 throttle it's too rich on the HSN, if it accelerates and then bogs it's too lean.

Ok, now its super rich and super slow and its still doing it, any ideas?

Check for air leaks and tune in really small increments. 1 "hour" at a time. Then drive it 2-3 minutes checking temps often.
