I asked about this before and was advised to clean the carb. What happens is my 426 wants to die if I just BARELY crack the throttle, just off idle. If I crank it hard, it revs just fine...it's when i just barely crack it. I took the jets out and cleaned them up, sprayed carb cleaner in the passages and then blew them out. Checked the accelerator pump squirt...everything looks good. The one thing I DIDN'T do was blow out the port where the fuel screw is. the fuel screw definitely affects the idle and I'm about 2 turns out...it idles fine, so I'm thinking the circuit isn't clogged. It's frustrating especially on tight technical single track where I am often at that throttle setting as I approach a technical section. I'm always having to keep it revved to avoid the dead spot. Any ideas? Could it possibly be the plug? (Fairly new platinum). Thanks in advance.
