Editing Talk:Finding vacuum leaks

== vac leak == you can also use starting fluid. just use it sparingly! Just to be safe,I use soapy water and listen for the engine to stumble,remember;slowly,and be patient!! I have used soapy water in the past,use a spray bottle,on mist. Listen for the engine to stumble,just remember,be slow and use it sparingly. lotsa,lotsa TOM ==Moved from main page== Fixing a leak. My old neighbor built circle track cars and after the ran the engine he would shut it off...tape off every opening with duct tape then put a hose over the dip stick and hook up to a vacuum source. He would then get his stethascope and listen in the area where the propane or carb fluid indicated a leak. he used Rtv and calked into the area until the stethascope whistle stopped. too much vacuum will pull too much calk into the hole. You can also use a smoke can that emits smoke and put it arounf the area you suspect and it will get sucked in.Sort of like what you see in those windtunnel test to check air flow. Paisano
