That engine comes with an S&S 600, average compression is at 180 cold throttle open.. by your numbers it looks like someone has changed the cam to a smaller version,,, the 600 has 600 lift, and 260/265 duration,, sounds like you have around 250-255 cam in,,, this will seriously hinder the performance of the engine,,, or way to tell is pull the cam, and the grind # is on the inner end of the cam, if it is S&S... the downside is,,, many ignorant wannabe engine parts hangers,, think they need a torque cam,, in a 113,, lol that is just plain ignorant..
The right jet combo will be around a 33 low speed,, idle screw out 1-1,25 turns,,, acc pump just under 2 turns out from turned off,,, it has 4 turns adjustment.. idle set at 1000...
The cam can cause hard starting,, and smoke batteries and starters....
I had one come in a burger 113 S&S,,, the owned wanted releases,, I did a ccp test it was 250 psi,,, I talked him into letting me remove the cam, it had a cam that would have been great in a stock 80 incher,,, he was well pleased with the 600 cam and a tune... I always kept a couple 600's and a couple 640' on the shelf also,, the Andrew's EV82 AND EV 84 are awesome performers,,, but it needs at least 11-1 compression or more...
Exhaust can hinder performance above 4k rpm..
