Secret of Engine Problem Diagnosis- Fuel Trims Pt.1
One of the best techniques for diagnosing check engine lights or engine
problems especially for lean or rich engine diagnostic trouble codes
(DTC's) is to examine and interpret Fuel Trim data. This video will help
the home mechanic learn how to use a very basic scan tool to develop
powerful diagnostic capabilities and prevent changing parts unnecessarily.
1926 Elto "Super G" Ruddertwin
Test running the 1926 Elto Ruddertwin. This is a 4hp opposed twin with
battery ignition. Motor is started with the knob on top by "rocking" it
backwards. Two lines are used to control the rudder.
Since this motor uses the "Propello-Pump" cooling we rigged up two water
feed lines to back-flush it in the tank. (Pressure/vacuum cooling systems
won't work in my test barrel)
Motor is being run off a 6-volt motorcycle battery and on a 16:1 mix of
Evinrude TCW-3 and regular 87 octaine gasoline.
Hiawatha outboard motor running in test tank. First run since 1974!!
I bought this from a guys estate for $25. Hiawatha outboard motor running
in test tank. First time started since 1974 (I was told by previous owner).
After I dumped expired gas out, cleaned carb and points, she fires up. I
have side covers. They were left off while testing was done. Next is going
to be new plugs, a good cleaning, and start tracking down a recoil.
Archimedes A1 antique outboard 1933, 4 Hp
The pistons and pistonrings of this outboard were completely stuck by coal.
I took the engine apart with a special tool I made for that job, cleaned
the whole thing up and welded a frozen cilinder.
Then installed new rings and good upper and lower bearrings (which unlikely
enough were left on my doorstep by someone last Christmas ... Thank you!
whoever you are)
Runs like new.
I did a Johnson A45 (1929) earlier this year and also ran it behind my boat
but this one runs much better.
6.2L LSA Engine Install & Lake Test
6.2L LSA Marine Power engine w/ Bravo III XR outdrive lake test. Engine was
installed at Michigan Motorz. Exhaust
was run THRU-PROP, not thru-hull to reduce Exhaust noise. Many components that were
installed are special/custom to make the 6.2L LSA work in a stern-drive
Eska Seacruiser 4HP Outboard Motor 1973
Found an old Eska two stroke in the trash. Air cooled and makes roughly
4hp. Model 1929-A. Just needed a float valve and a good carb cleaning.
Thanks for watching!
1949 Mercury KF7 Super 10 Lightning
If you like this video please vote for it in the Mercury Films Festival!
This Mercury KF7 Lightning has been completely rebuilt and has about 5
hours on it.The water was a little rough due to some wakeboarders, so it
was difficult to run at full throttle for an extended period.
1950's Elto Outboard 5HP - Running Great
Pulled apart and gave the carbie a good cleanout, re-set the points gap
(.020), and this is the result.
Great outboard, can't wait to get it out of the garage and onto the water
for some trials.
