Question about recurve ? (1 Viewer)

[NeverGiveUpYota]

I'd like to know that information as well. My pig, Bucky, has a bad primary vac pot. Right now it's just running mechanical advance with a little boost from the secondary diaphragm. I'd like to source a new vac pot one way or another.

As I said, he can’t rebuild the pots unless he gets enough folks needing it to help fund the tooling he’d need to rebuild them. He explained at length in the vacuum advance thread, (I can find) that he really doesn’t believe our distributors need a two port system. I do know Jim I believe responded he feels otherwise.

The two port system is there to support the HAC system. So I'd think for those of us living in low elevation who rarely if ever see high elevation we'd be fine with a single diaphragm. But maybe there is some other condition it becomes active at I don't know about.

@distributorguy, Jeff can recurve but no vac adv pot rebuilds. @FJ60Cam i ‘think’ was going to have him put a non oem vac adv single diaphragm on his. I’m curious myself if that went well?

I've engineered a simple modification to a Toyota non-Land Cruiser single diaphragm advancer that has an almost identical vacuum advance curve to the FJ60 distributor's main diaphragm. I've got quite a few of these new NipponDenso advancers available, posted in the For Sale forum:

Vendor - NM New NipponDenso Single-Diaphragm Vacuum Advancers for Big Cap Distributors

I've engineered a modified NipponDenso single-diaphragm vacuum advancer for installation into '81 and later 2F distributors. The advancer has a vacuum advance curve almost identical to the main diaphragm in the OEM advancer. This advancer is a great alternative for those Land Cruisers not...
