Point Gap 225 V6

hello

Does anyone know the specs of a coil of a 225 v6?
And when I change ignition points does the timing changes also?

Have suddenly problems with starting;

battery is OK
there is a spark on all cilinders
fuel is pumping ( acceleration is squirting fuel)

It wont start, and smells fuel after a while

THe specs I read are 1,4 and 7,94 on the coil. (primary and secundairy)

 

Point Gap. Isn't that a town in New Mexico?

Check your timing statically (with out the engine running)
Set the point gap to whatever you get using a matchbook cover as a gapping tool. should start at this point.
Then reset the point dwell using a correct size allen wrench and a dwell meter. I don't remember what the dwell is supposed to be, but someone here can tell you.

 

If you smell gas, it's probably flooded.

Yes, you can set the point gap roughly and the car will still start and run. It does change the timing when you change the points.

Are you trying to measure resistances of the coil primary and secondary? It is hard to get an accurate measurement of low resistances with a multimeter. I'd suggest you try another coil and see if it makes any difference (I think it will not if you have spark already). If you can't take one from another car or pick one up at the junkyard, a spare coil is a good thing to keep in the Jeep. They can and do fail suddenly - BTDT.

 

im pretty sure the point gap is .16, and the dwell is 30. timing should be set to 5* I believe.

 

Just remember to reset the timing after getting the dwell right. Changing dwell will change the timing. Timing will not change the dwell. Once that is all done, then you get to reset the carburetor.

 

Thanks for this information. It helped.

Don't know why, but 0 degrees bdc does not sound right. Thought it should be either 5 or 10 degrees bdc.

I've always heard "before top dead center" so BTDC ...

 

I believe it's 0 deg with a Prestolite distributor, and 5 deg with a Delco. Don't know why it would be different?

 

Because I have no visible timing marks on my block or timing cover, I started at 0º TDC as my starting point just to get it started, and then used my vacuum gauge to set the idle speed timing once it was running. Observing your gauge, you then advance the timing until you get to peak vacuum. (about 22º or 24º, but could be lower, depending on your altitude.) Once you reach the peak, stop, then back it off until the needle just starts to drop, then snug the hold down bolt to keep it from moving. Reset your idle and mixture. Let the engine get good and warm (your normal operating temperature that was observed while your were running around in the JEEP before.) Now shut the engine down, and try to start it up again. If it starts right up and the starter motor spins like it should, then tighten the hold down bolt to what it should be. If it acts like you need a new battery, then ease the distributor a tad bit, then try to start it again. Keep backing it off until your starter motor spins like it should and lock everything down. You are now timed. My distributor doesn't have vacuum advance on it so I don't have to worry about that. Those of you that have vacuum advance need to disconnect and plug the line for the vacuum advance to do this procedure, and then hook the vacuum advance back up when you are done.

bet your gas mileage goes up,, too.

 

BTC is Behind Top-dead Center, meaning -5*. TDC is Top Dead Center and would only be seen written such at 0* probably. Probably left the D out of BTC because everyone likes TLAs.

 

BTDC means "Before top dead center"
