The Agony of New Parts

[Dogbomb]

Yesterday was my 5th outing on the Seafari, and the best one yet.

The Suzuki 140 I purchased only had 60 hours on it, but had been
sitting in the high desert unused for 7 years. I replaced all the fuel filters,
low pressure and high pressure pumps, fuel lines, and thoroughly cleaned
the VST before I ever fired her up.

The engine would run perfectly at low speeds, but would sputter and act
fuel starved at 4,000 RPMs and above.

I pulled and cleaned the fuel tank. Rebulit the VST for a second time.
Replaced the needle and seat. Tried different float heights. Tried running
her off a known good 6 gallon tank. No luck.

So I started over. Bought a cheap electric fuel pump, plumbed it in at the tank,
and pulled every fitting, testing as I went for fuel flow.

Turns out the second filter in line, the BRAND NEW Suzuki low pressure
filter was plugged and would only trickle gas at 4 lbs of pressure.

I hack sawed it apart and discovered that a small piece of the plastic casting
had flopped down over the inlet and was occluding flow. I replaced it with the
generic Sierra filter, and now she runs perfectly.

Did 40 miles yesterday without a hiccup. Now I can get back to playing
with motor height and fine tuning prop selection.

Stupid factory parts...

Yep, "new" doesn't always mean "works correctly! My "new" sierra fuel gauge is reading empty when off, but 1/4 tank when full. Then it does not move at all that I can see! Some calibration issue I wonder?

Glad you got 40 miles in.

Man you got that thing cleaned up and looking sharp! Congrats on the easy fix!

It's always the simple stuff but tails of woah from other forums had me down the wrong expensive road before so I have learned to go back to the basics like you did. Glad you got it worked out and running good. It's a good feeling.
