Dual quads versus big hammer!!!...
Do you really think the two inch open spacers are hurting?..
I’m not there seeing how things are playing out.
A lot of it is “feeling” how the motor behaves, and
when it does certain things in relation to throttle movement.
But, if there are tip in issues........ask yourself....... where is the squirter....... and where is the combustion chamber(you know, the place where the rich/lean thing happens)?
And....... what’s in between them?
If the squirter was 12” farther away from the chamber....... would you expect the problem to get better or worse?
How about 24” farther away?
If the squirters discharged directly into the intake port of the head, right behind the valve...... better or worse?
Thats not even talking about the “accumulator effect” of having all that plenum volume dampening the signal to the carb.
But....... it also may not matter at all on that combo.
As with most everything in this hobby..... there’s only one way to know for sure.
