Does spraying carb cleaner directly into the intake actually help or are we just wasting our time?
I saw a big difference on my '86 F150 after I took the carb apart and cleaned it by hand. Before that I'd just spray cleaner down the throat while it was running and it seemed to help for like a day. Then it would start idling rough again. Over about 3 weeks of doing that I noticed the gaskets started swelling and I got a vacuum leak. Now I'm wondering if the short term fix is worth the longer term headache. Any of you guys seen this go sideways too or am I just unlucky?
