74 2.0L. single carb. #4 head had both exhaust studs broken. replaced head, and now it won't hit on three and four.

Its got fire and gas. vlaves have been checked, and rechecked three times. The replacement head came from my personal car that got a new engine last week. I don't believe the head is the problem.

I'm stumped. Anyone got any ideas? What am I overlooking?

TIA, Curt

Could you have accidentally swapped plug wires on those two cylinders? That would certainly do it.

Did you do a compression test? Leakdown?

I know this is a silly question, but are the plugs new?

Are you sure you dont have a seized valve? Maybe a bent valve? How did the head look when you put it in?

Compression is 135 on both cyls. No leakdown. Plugs are new. no bent or siezed valves. This head came from my car. It was completely redone just over a year ago.

Why would two cylinders go out? And only when he replaced the head? I dont think its dizzy related... but its always possible.

i was getting ready to say the magic word--(trigger points) but i honestly swear your plug wires are crossed.....try to start it with the gas floored. if it pops every so often, your plug wires are crossed. happened to me b4.

Matt, that is exactly what has me confused.

Britt, thanks, but if you read all my post, the wires ain't crossed and it ain't the diz!! If it fires at the plug, it ain't the diz! Oh, its carbed. It ain't got no trigger points!!!!

Curt,

It can only be one of two things:

1. Compression, spark or fuel diagnostics are FLAWED! (IMG:http://www.914world.com/bbs2/html/emoticons/w00t.gif)

2. The magnetic convergence field which hovers over Tulsa is matriculating particulents of the lower participles left brain/right cylinder unsuccessful synapse, resulting in NO SPARK!

I guess I tend to agree with bd1308. It's all about the SPARK! (IMG:http://www.914world.com/bbs2/html/emoticons/w00t.gif)

post script: bd1308, Curt is the simmer man. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

speaking of spark.....i like how i can work around the plug wires (and even put my arm next to one) without it shocking the hell outta me. The Jeep always did that hurt like a BEEOTCH

Well, a LOT of what I have come to know about teeners has come from Curt...so I guess in some ways I'm his right brain. Fortunately he still has something that's left. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

Curt, I know this is going to sound stupid but here goes. Did you turn the engine over while looking at the valves move? Did you put the pushrods back in and they seated? When you put the motor together, did you check to make sure you put everything in right? Not saying that you are stupid but we all make mistakes. Go back through and check everything. If you have compression, spark and gas, it should fire, period. Check your wires at both ends too. And your plugs. Good luck and post your findings.

I agree. Something was overlooked. Go through the steps again and I'll wager that a small issue was overlooked or came up during re-assembly and was missed. You are a smart guy, you'll figure it out

NOPE! That does not sound stuplid. All good comments and observations. I talked to him about the exact same things.

I asked him if there were any "extra" pushrods lying around. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

A good compression check says the valves settings are correct.

Single carb? Most likely no fuel distribution problems in that system.

Although, I must ask... Curt... WHY are you running a single CARB????? (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)

Have you no shame? (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

It's gotta be all about the SPARK!

Well, you know if there are no pushrods, the valves wont open and the compression would be high. That is why I asked if he looked at the lifters to see if they were moving when he turned the engine over. If they are opening and he has compression, there is no reason why it wont fire except a freak of nature.

Could be just that... a freak of nature...

Some say that T-town itself is a "freak of nature".

I have dated several ladies from T-town... some... I have to admit... were freaks of nature... but... they were ladies...

I'm still thinkin' that it's SPARK...

or...

...#2. The magnetic convergence field which hovers over Tulsa is matriculating particulents of the lower participles left brain/right cylinder unsuccessful synapse, resulting in NO SPARK!

just waiting....
