Rescue CBR 600 F2
 

Practically free 93 CBR F2 in great condition with rust/varnish issues in tank and carbs. Got it running again after sitting for @ maybe three years in storage, after so carb/ tank deep cleaning. Concerned about lower compression, header heats, and low idle stumble. Cold compression reads lower on two inner cylinders and header heat is not even on all pipes on warmup. The lower idle miss can't be eradicated with idle mixture adjustments especially on 4, mixture screw has no affect?
My backyard engine and carb knowledge may be to blame for some remaining issues, but I'm enjoying this for the most part --love the challenge. Would really appreciate some input before I loose my healthy head of hair though. Been down the block a few times and seems to respond nicely but just not sure.
Thanks Rescue CBR @lpowers63
