all the old timer mechanics i know swear by the stuff. but personally after trying it a few times i have yet to find a situation where it has wowed me. i think it worked so good back in the day because they had such crummy gas standards. like everones saying its worth a shot before you go in to clean carb.
nothing beats a paint can of chem dip, just remove anything rubber from carb before dipping and dont get it on you. my skin is tough from years of abuse but i have heard of some cases of nasty chemical burns. ive had clogged tiny hole idle jets able to see light through after one night.
