Good afternoon
I am getting my 250 Challenger ready to race this season and I decided, after some advice of fellow owners, that for ease of tuning that I wanted to use a Concentric rather than a monobloc. My bike is a one-owner unit that came with original service notes and a box of spares. In the box of spare was a labeled bag that contained a concentric carb, and was noted to be jetted for the Greeves. After a thorough cleaning and a new float bowl to replace the slightly warped one, i installed it along with a new cable. The bike revs fine, and I am still adjusting some things overall to be able to really test it....but this particular carb has a four stroke venturi/sprayer. Is it possible that it will run fine with this setup? Could it be possible that the original owner bought the wrong carb and then put the monobloc back on after he couldn't get it to run right? I have ordered a brand new amal premier two stroke...but while I wait for it I want to know if I am spinning my wheels by attempting to tune essentially the wrong carb.
