If R45 is normal is R44 1 hotter or colder???

 

44 is colder than 45.

 

Ahh ok, I wasn't sure. some go up some go down.
I know autolites goes down for hotter.

Though can I even get a R46 easy?
Or order online?

Am a bit rich, better then lean, not a pro carb tuner, and I sometimes get choke happy. [real man choke] Thinking 1 hotter would help make em last longer or be a bit more forgiving.

 

DUH

sparkplugs.com

looks like I gotta go Denso to get 1 hotter.

It's trial and error picking the proper heat range for plugs. You need to read a new clean plug to see where the discoloration is on the ground strap to determine if it's the correct heat range for your engine.

Use the coldest plug possible that doesn't foul up. Too cold and it can't burn off the deposits. Too hot and it will melt the electrode.

 

Ended up cheaper to have Advance Auto order the
Denso 5021 [1 range hotter]

Only $1.98 over the $2.98 online, though its a 3-5 day order as it comes right from Denso not their warehouse.

No one carrys a good selection of plugs anymore.

Course I know it just the times, as car parts stores no longer buy products to stock. They are given products and only have to pay for them once sold.
Cause of that, companies aren't willing to give them parts that might not sell often, so they only stock the most popular ones.

 

Finally got the Denso's

Look nice, made in Japan

Will install on the morrow, run for 1 day then install the MSD so I got an idea of how they work in their own.

Talking on another board AC n Autolite are made on the same line, by the same company.

 

how much hp are you making?
its better to be too lean than rich.
rich conditions will cause more havoc than lean most of the time.
its never good to get a plug that stays clean at idle, because it will be SUPER HOT at WOT and possibly burn a hole in your piston. plugs can turn into a torch in an instant.
tune your issues. if you cant fix it, ask for help from either posting your issues or finding someone local to lend a hand.

 

Didn't change the plugs, went straight into seeing if the used MSD worked.

It did.

Odd though it felt down on power?

Gonna recheck timing and everything, tried but can't read balancer well enough anymore.

 

msd will help keep the plugs cleaner at idle than through a std or hei ignition.

 

I was hoping the dual spark up to 3000 would help mileage a bit, even 1/2 more MPG would be good, since it spends most of its time in the 2-3000 range. But I probably lost 3-4MPG on my test run to the store for some better wire n spade connectors.

I hope that re-doing things helps other wise it will come off.
Just glad it wasn't full price.

 

Had a brain fart, I forgot about subtraction the initial.
So I wans in the 40 range OOOPS

But re-wiring and re-routing everything proper fixed things.

 

Im perplexed now, double checking everything this am I never plugged back in the vac advance and it was running great that way.

Wonder if cause I got light springs it don't sort of matter, ehy?

As Im all in around 1800

at idle unplugging the distributor won't do much. Probably would run same. Its when you at wot or driving hwy speeds you will notice a big difference since it sucks more vacuum on the advance if its not hooked up it will run like crap. WIth that being said i am no expert so I maybe wrong. Forgive me :P.

 

It should but it wasn't that bad unhooked.

And can't talk to my guy who built n set up the dizzy.
Though I don't question anything he did as it would be like questing Bill Gates or Steve Jobs on why he did what he did building you a computer himself by hand but.......
