Treats 70cc cylinder kit

15mm bing clone 2.15 atomizer with #1 grandpa intake don’t remember the jet.

PROMA circuit pipe
My problem is with four stroking at top end, I’ve gone up and down with jetting then went to the 2.15 atomizer that did help but I’ve still got the problem. So I’m wondering if I need a bigger carb-intake but here’s the issue is it will be going on a pinto and the frame might be in the way of the carb. So what do you think, More carb or ?. thanks for any and all help.
