Hey gang.
1989 seacraft 20 cc
1600lbs
dry solid hull. AV plate 1 1/2 " up. SST 1 prop 15x16 no dings
Comp 105-110 all 6. Spark jumps 3/8 on all at idle.
New BRP carb kits fixed sneeze/stall issue.
New fuel tank all hoses to engine. Holds plane at 2800 at 12 mph. That`s the good news.
No anti siphon valve. New racor, BRP vro pump and Primer solenoid. Both were cracked and leaking...
On engine filter clean. All 3/8 A1 hoses.
Only rec 90 fuel. Premix 50-1 w Penn semi xlf.
The racor housing is old and shows corrosion. Could this be restricting flow/ allowing air in?
Carbs were soaked in power tune 24 hours before new full bowl kits installed. All passages clear with soft copper wire.
Plug wires seem to be original. Champ ql78yc new gapped at .030. Bottom two plugs were at .020. I did not check gaps before old plugs were installed.
Will check gaps on all new ones moving forward...
