Does anyone know where I could get my distributor recurved? Looks like Jim has been out of pocket for some time.

Also, interestingly enough when I pull the choke part way out the pinging goes away, I'm thinking this must be carb related rather than ignition related. I'm going to re-jet to see if that makes a difference.

A couple updates. I cut the fuel filter open to see how bad the rust problem in the tank was, I was surprised, the filter was clean. With that result I decided to clean and rebuild the carb. After the clean and rebuild, varnish was terrible from sitting with old fuel, and a newly crimped wire connection for the fuel cut solenoid I restarted and found that it ran far better than before but still had some erratic idle. I started looking at the ignitor/coil and distributor and found that I was lacking a good ground for the ignitor, and that the coil wires were loose on the coil. Fixing those issues along with the carb made it drive-able. The story isn't over yet, while driving it has a pretty heavy ping. I checked the timing adjustment and at this time it's 7degrees BTDC and it still pings. I'm thinking due to the high performance cam, the custom domed pistons and the de-smog I'm either going to have to re-curve the current distributor, buy a new non-USA distributor with points and ballast resistor, or a DUI. Still trying to decide the best route to go.

Thanks

I had my 74 fj40 2f in the shop of and on for years. They were constantly scoping it. It never ran right. Then I bought a 76 FJ 40 and started the project. I tried for the heck of it putting the 76 distributor in the 74. It never ran that good for years. Come to find out the bushings were wore out in the old distributor. So a word to the wise try putting a new distributor in the rig. Get rid of the points go electronic type. Just FYI. I'm so thankful I tried a new distributor. I paid mechanics for nothing all those years.

Thanks for the advise. After re-jetting I still have the issue so at this time I’m thinking the recurve/rebuild is the answer, I believe the weighting/spring rate is off for all the changes I’ve made. I’m thinking Toyota Non-USA Distributor with a Supra electronic module, still researching this option.

Not familiar with those let me know how it works for you. Is yours a 2f engine?

Yeah, it is a 2F. Adding a photo for viewing pleasure.

So I ended up buying a 19100-61180 distributor/Pertronix combo from CruiserTEQ, should have it next week, looking forward to seeing the outcome.

Tell me more about the Supra module?

Sorry, it was a Celica and I was referencing the thread here. I didn’t dig too deep into the details, just decided to go with the Pertronix. I did like the all Toyota option though.

Distributor Tech - '75 through '77 Conversion to Electronic Ignition Using Toyota/NipponDenso Parts

This evening I finished upgrading a lightly used 2015 Trollhole electronic distributor using Toyota/NipponDenso parts. I replaced the stationary (breaker) plate with a '78 through '80 2F stationary plate, replaced the electronics with a new Camry (Celica, not Camry - it was late at night when I...

I finally installed the distributor. It made a huge difference in drivability and power and I’m real happy with the outcome. Sad thing was I still had a pinging issue. As I was driving around I noticed the pinging would stop when I was into the secondary. I also determined the pinging went completely away with the choke pulled. With that discovery I decided to rejet the primary to get more fuel. I replaced the primary with a 171 and took it for a ride and the pinging was gone. I’ve now got the timing set at 7degrees, 171 in the primary and the secondary a 200. It’s got great throttle response and no hesitation. Looking forward to driving it now.

I was still having surging idling issues and reduced low end torque. So I decided up the timing to 14degrees and increase the primary jet to 180. So far seems to be good, but only time will tell. Just documenting changes for myself and others.

Do you have any pinging at 14 degrees?

Thanks for the question. At 14 degrees I was still getting slight pinging even with premium fuel. It was mainly happening under heavy load and/or when I was into the secondary. I ended up re jetting the secondary to 220, and backing off the timing to 12 degrees which seems to be a sweet spot. It’s idling good, good power, starts well, exhaust smell is as expected and no pinging. I think I’ll hold here and see how things go for a while.

Thanks
