fuel pump fitting question and another about timing

Post by 6t6 » Sat Jun 10, 2017 5:30 pm

Replaced the fuel pump my question is about using anything to seal the threads on the fine thread fitting.Image

I understand the coarse threads don't require anything, Im just curious about opinions on the fine thread side.

Also I had the motor rebuilt and have no idea where the timing needs to be. Any suggestions?

I wrap a little teflon tape on the fuel pump side.
I could look in the book and tell you where the
Timing should be. But we have different gas and
There may be some minor changes when your
Motor was rebuilt. Start by getting it warmed up
And back it down where it won't hesatate when starting
Then where it will not ping when you accelerate.
And play with it from there. I run mine on regular
And have it where it may ping a little if I got on
It real hard.

I use a bit of ptfe paste on these threads, even though it's not technically necessary. The paste works the same as teflon tape, but there's less chance of fouling the line (or carb) with it.

If you rebuilt the motor to stock specs, start with an initial timing of around 6 degrees and work from there.

Search the Forum for topics related to timing using a vacuum gauge. A slipped harmonic balancer/vibration damper and today's fuel quality are two good reasons to try timing with a vacuum gauge.
