I was told once that a lectron 48 is equivalent to a 46mm on other carbs. Is that a true statement?

Yes and no, a HV, (high velocity) has a 2mm reduction in the center to increase the pulse. Lectron makes a regular straight and a HV, the regular has no reduction.

i only said Q to be funny, haha lol get it. he is the only one that can build a motor like that in his eyes.
guess it went over a few heads. lol

Had me worried there Grk, I thought aliens must have abducted you
