28mm carb baseline jetting?

[mookie]

i have a 28mmKeihin roundslide ,CT mani/72cc Taiwan/V8 pipe
and i need a starting point on the jetting.
it has a 145/45 in it at the moment.
haven't as much as started it yet.
any input from those who have been there done that appreciated.

My 28 OKO was setup with 138 main and 55 pilot. 72cc, CT mani, R1 pipe. Seems similar enough but my OKO was 28mm flatslide not the Keihin roundslide if it really matters. I also ran the uni foam air filter.

cool- i 'll give it a go with the jetting as is for starters.

If i dropped under the 55 main and gave it WOT from a stop it would bog or stall. Just sayin you might get the same condition with the 45.

damndest thing!

it runs WFO without touching the throttle!
clearly an intake leak. but how? where?

tried two identical carbs. no the slide is in correctly.
didn't see a crack in the reed block.



gonna go out in a bit and take it apart and see what the

heck is going on- i hope.gotta be something simple i've overlooked.
