0.037 did almost work but even after warming up the engine enough it was slightly hesitating when slowly pushing the throttle in. However when pushing throttle quickly the accelerator pump squirts enough to overcome this area. At higher revs the thing is flying so now I need to find a way to richen up the area when just moving the butterfly away from its stop. I found that the mainjets are perfect now but the pick-up is a little bit too lean. I need an expert to tell me what to do next. Meanwhile I fit the 0.040" jets as they are rich enough to cover the low throttle area as well.
Anyone out there knowing what to modify/change for my problem?
