So if I reduce the size would it fix the problem?
I don't have a meter but I have measured it before and using the same amount of wraps
My 28 gauge, 9 wraps gives around 1.4 ohm, dual coil.... .74 ohm..something like ....and that's measured on ohm reader...so I think you're reading/estimating it wrong
Head over Home Depot and find two drill bit.
while at it, you might want to read this.
