Good point- but I ddnt get that far... Looks like it may be a carb issue after all. I pulled the bad sides plugs and squirted soem gas in the cyl then put the plug back in. then shorted the entire good side and tried to start the car. Wouldnt start. Thinking maybe I put too much gas in the cyl I held my foot to the floor and tried again- It started and ran. As soon as I took my foot off the pedal it died. Hold pedal half way to floor and start it - It runs. Runs rough because half the engine is still shorted but it does run. SO it looks like the carb after all. I still dont understand why it is only effecting the drivers side- The reason I ruled out the carb was because of the intake design- half the engine shouldnt be effected by a bad carb. This will be the second time this damn holley carb has caused me soo much problems. Im gonna buy a new carb and throw this one at the wall.... I'll report after I get a new carb For all of you that said carb and I said "But that cant be" YOU ARE THE MASTERS, I AM THE IDIOT!

I told you it was carb or vacuum. At least now you know. Post pictures of your spacer and gaskets.

I look forward to the results with a different carb. I question whether the test you are doing is verifying anything.

I would R&R the intake gaskets 1st & give the offending side a close visual when you come apart

To check for an internal leak you need to get some gas into the crankcase, propane will work fine. Start the engine, open the gas valve on the propane tank feeding the gas either to the pvc opening on the valve cover or the oil fill on the other side. If there is an internal leak then the engine will smooth out when it has injested the propane. If this isn't it look at the idle circuit of the carb since you are only seeing the problem during idle.

This is just one HELL of a good way to blow up a crankcase. Where did you find this nonsense?

sounds like a hell of a good way to have big explosion and or fire. Of course then the problem would be solved.

You guys are just lucky, and there IS an ignition sourch in the crankcase, especially in older engines---it's called blowby
In my lifetime I've been directly privy to at least 3 cases of crankcase explosions--admittedly these were all caused by fuel pumps leaking fuel into the crankcase
CASE 1 About 1973, Sand Diego, CA. I was on TAD from Miramar, at the "downtown" Navy shore patrol, the "old" San Diego jail. A habitually late sailor had a weird excuse for being late--and I demanded proof. He said his kid started up his 57 Chev to warm it up and BOOM. It drove the oil filler cap off hard enough to dent the hood, blew one valve cover off the engine, and ruined the other cover and pan
CASE II Aftermath, a friend had a 68 Ford 390, also in San Diego. His engine just warped the front/ rear pan seals and blew out the dipstick and filler cap. We weren't smart enough, then, to realize what happened. When he took the car in to get it fixed, the mechanic said "probably the fuel pump", and it was
CASE III After the navy, we were leaving a local cafe, someone had jumped into their 78 Ford Granda/ whatever and cranked the ignition. This was a cold winter night, and BOOM came sparks, oil and junk from under the engine. We didn't stick around, only to take a quick look under the car. It obviously had tried to remove the pan.
These were all caused by fuel in the oil, but it doesn't matter. Anything you do to set up a combustable air/fuel mixture in there, and a little "flash" by the rings is all you need.
Where did "we" learn this propane / acet "trick?" Is this being taught in some mechanics school? Is it in some manual / book you bought? I've never heard of this before, but as a guy who used to service HVAC, including nat gas/ LP/ oil heat, I'll guarantee you that if you do this enough, you'll regret it.

Better step back on your rant. Propane was once used to set carbs up. It was an authorized mopar service procedure. Properly used I see no problem un using it for a vacuum leak. A running motor is going to burn it not deposit it in the crankcase. There is a lot you obviously do not know.

Well.... I didnt blow up it wasnt the carb. Although I need to look into better filters- with 2 filters I still had crap in the carb. Problem was the intake valves on the bad side. The lash was spec according to my manual but just because I was about to give up I pulled the valve cover and loosened the intake valves a half turn and fired it up. Immediately the engien sounded better. put the cover back on and tested it . That was it! Only thing I can guess is the lifters are pumping up higher after it is running. And apparently the are pumping higher than when I first got it on the road. DEFINTITY PROBLEM SOLVED!!!!!!!!
