GarnerFJ40's Progress

[GarnerFJ40]

So, running rich was due to the primary and secondary jets being reversed. Caught that while I was in putting the jet on the power valve. That's fixed.

"Borrowed" (it's mine now) my brother's timing light and got it adjusted (as much without adjusting the valves, Thanks for the input Kalungot!). It was a little off, and I bypassed the VSV. Was running good...

Until I stopped for fresh fuel. My thought is I'm sucking something up from the tank...

Limped it home, dumped the gas, pulled the tank, and blew the lines out with air. Visited the gnomes at the other house and grabbed my spare gas tank (Yes! I have a spare!) and am going to swap it in. The old looks OK, and not much debris/rust fell during the draining/inspection, but to rule out a restriction, I'm swapping the other in.

I'm now debating on 1) replacing all the line with new hard and rubber line or 2) going completely flexible and reducing the number of connections between the tank, filters, hard line, pump, and carb.

Thoughts?

Fresh fuel filter and blow out all the lines with compressed air. Just a thought.

I'd replace the lines. A few years ago when I lived in LA I was hanging out at Mark's Off Road with Mark Algazy and John (Calico) while they were working on a really nice FJ45 I was welding up some some water carriers for Mark's 45. Mark had cut open a otherwise very clean looking fuel line to show that it was totally rusted out inside and had huge flakes of rust in it. And that was the high desert out west of LA! No east coast humidity!

Clearly not something that you want in a newly rebuilt carb!

The problem is that the rust flakes get into the fuel filter and then continue to break down into smaller particles through vibration and even further corrosion until they pass through as a fine silt that is

Got a vacuum guage and a hand held tach? (all my stuff is still in storage)

I'll come over and help you dial it in.

I could use some wrenching time to clear my head.

PS fresh gas is always good. Many many times I've tried to help someone fix a Cruiser that ran like crap - they will rebuild the carb, get a new distributor, tune it up, etc and nothing seems to fix it. Simply dumping the fuel and cleaning the tank then putting in a new tank of fuel makes the truck finally run right as water has accumulated in the fuel. Use the old gas in your lawn mower.
