Your testing of various ‘alternatives’ has been fun to follow and I know many share your dislike of jet changing.
I am curious as to whether you’ve heard of the APT Smartcarb. It is a single metering rod style of float carb with an ‘auto’ compensation circuit for air density. It can’t be tuned ‘on the fly’, but once dialed in thru rod height adjustment and idle screw it compensates for any air density changes.
I currently run a 38mm cast model (they also make them in billet) on a Swedetech 5 degree offset boot thru a VForce 3 reed, fed by Dellorto pump (no tee/return). The rest of the motor is Stock Honda as I was not looking for the fastest, just ease of use. This is on an F125 laydown so Stock Honda rules are not applicable.
Just an FYI for those looking at options.
