At idle it's runs like hell And higher rpm it's fine indicating vacuum leak I covered up the carb mouth and ts still ran anther sign of leak. Crab sprayed the intire intake and all th vac lines no noticeable blip in revs up or down. I checked the modulator. No leak what am I missing help please

You'll think I'm crazy. I have found some vac leaks that would not show up by spraying carb cleaner by using a length of 3/8 fuel line like a doctors stethescope. You will be amazed how much the hose will amplify the sound. Just run the end of the hose along the carb and intake anything else that takes vacume while holding the other end to your ear.

Is this the same one that in a diffrent thread you said it had gas in the chracoal canister?

If so you need to pull the top of the carb and see if it has any of the charcoal out of the cannister in the carb. I've seen it many times. The charcoal will get in the jets and make it run like crap.
