Still a miss at 4,000 RPM..., Backfiring at WOT, even with all new ignition components Options

rotor at notch on top distr body (if the body has one). 0* fan mark in the indicator notch. #1 wire terminal. doesn't need to be off by much to disrupt things.

Didn't have time to work on it last night, but I did some reading:

It might be possible that the distributor drive pinion (the offset fitting at the base of the dizzy shaft) is installed 180 degrees off. I pulled out the roll pin right after I got it so I could re-shim the pinion, and I guess it's theoretically possible that I put it back wrong.

It does not, however explain why I have the same problem with 3 different distributors though.

[rhodyguy]

depends on the indexing and wire placement. if you are replacing the wires as before you're repeating the same behavior. the indexing being wrong is not so much in the distr as it is the dist driveshaft. the cog in the distr only fits one way into the shaft. look on pgs 64 and 65 for the text and fig 3.6 for the drive orientation @TDC.

Good call Kevin. In my mind, there was only one way to install the "cog", but since I don't have one in front of me, I was spitballing what was in my head.

So glad you made it to the WCR man! All that hard work paid off.

no hard work involved driving a car with 235hp, ac, partial leather seats, and sat radio. (IMG:style_emoticons/default/wink.gif)

So,

You went off and bought a total chick car, and now you just stopped working on the 914?

[rhodyguy]

richard, the "bought a total chick car" was directed towards me or george? i just want to be absolutely sure before i reply any further.

[edwin]

I would assume its aimed at the miata that George bought.
Will be interesting to see if the msd changes the timing problem

[ThePaintedMan]

It was directed at me (IMG:style_emoticons/default/dry.gif) . FYI, I haven't gotten to enjoy working much on either the 914 or the (IMG:style_emoticons/default/cheer.gif) car. I have no garage down here in Florida, and it has rained throughout the day for the past, what seems like, 2 weeks. So during the summer my choices are: work out in the sun, or work in the rain. (IMG:style_emoticons/default/biggrin.gif) But thanks for the (IMG:style_emoticons/default/poke.gif) Rich, you're right, I need to get moving on it.

My next goal is to finish wiring the MSD as well as cutoff switch, since I know that currently the engine at least starts and runs fine most of the time. I'd like to get my wiring all set and reliable, then I'll swap out for this spare engine. So I'm not adding more unknown variables.

[ThePaintedMan]

Didn't get to the MSD today, but I made some progress on my cutoff switch/ignition switch/push-button start. Not as much as I had hoped, as it seemed like everytime I went back outside, it would start to rain again. I feel like Charlie Brown with a cloud always following me around.

Wiring confuses the heck out of me. It's both an art and a science that I'm really not cut out for.

Everytime I turned around it was Raining - I must have gotten at least 3" at my House and it's starting again

ITs not art nor science, its wiring which is very logical.
Once you understand how a relay, coil, condenser and points work...the rest will fall right into place for you.

And its raining again.
Seems the east coast is getting hit with quite a bit of rain this year....and we need it, so w cant really complain to much.
But, I do have a place to work indoors...

So, how's that miata running?

[balljoint]

All that rain has been my fault. I've been rain dancing non-stop to help those 12' trees take root.

I am still, however, waiting for George to figure this out.

[ThePaintedMan]

I runs quite well Rich. And I even took the top down the other day to let the wind blow through my golden locks, just to piss you off. (IMG:style_emoticons/default/theexperience_hud.gif)

Still working on wiring for now. Got a little work done yesterday and was GOING to work on it today till Dave must have started dancing. Hopefully sunshine the next few days, since my fiancee will be gone to the Keys for her bachelorette party. I have the driveway all to myself.

The plan is to finish the wiring in steps so I can check that I didn't screw anything up along the way. If the engine starts up again and nothing catches fire, then I'll start working on dropping it for the spare.

Hey Dave, if you're having any real dry spells, I learned a trick for planting trees and keeping them nice and watered at the roots. You can take 2 liter bottles and attach PVC at the end and push them into the ground till you get to the root ball/zone. Works like those little glass watering balls for household plants. Usually they'll last 3-4 days before needing to be refilled. You can also add a mixture of starter fertilizer that's high in phosphorous (20-20-20 works well) with the water to get them going.

[r_towle]

Just don't let people see you with split ends....bad form.

Good luck with the wiring and I for one would like to do a triage on the motor to see why you think it may be the engine at this point.

If and when you take it apart, check the position of the timing gear in relationship to the crank gear and see if the dimple marks line up properly...before you pull the camshaft out of position.
