The problem:
Stalls when attempt to engage gear. Once underway, WOT 1200/1500 rpm. Fast idlee fluctuates back to 400.
Attempted fix:
Compression check OK. 108 - 110 all cylinders.
Drained carb bowls & filled with Sea Foam through fuel lines. Soaked overnight.
1gal of ring free shock treatment through engine over 3 treatments.
Engine submerged in 100 gal tub. Water line above anticav plate
New plugs. Fresh gas w/ stabilizer. Clean fuel filter.
All timing and idle settings to specs (motor running in tank except for advance timing set statically). Idle good. Fast idle holds steady at 1200 - 1500 rpm
Back at the ramp:
Same problem as above. No improvement.
Question:
Is "off block" carb clean and rebuild my next step? Is there something else I should check?
