Gas Cap leak
I have two Briggs and Stratton engines (91202 model) with the plastic cap. Both of them leak from around the rubber seal on the cap. I tried a new cap and it still leaks. For my first one I used gasket maker suitable for gas and made another gasket, and put it between the rubber gasket and the cap. This works somewhat but not perfect. Do any of you have any ideas as to why these motors leak from the cap(is this a common thing with these engines) and how to solve this problem? I searched around the site and could not find anything specific for these motors.
Thanks miniwood, it doesn't make sense as to why it takes several caps that are all the same. Also one of these tanks is rusty, I searched the forum and read that evaporust is good at eating away the rust, but what do you guys do after you clean it so it doesn't come back?
Can you take pictures? My old honda clone leaked from under the gas cap. It wasn't much, so I just didn't worry about it. Does it leak only when the tank is full? Also, the best way to keep rust off the tank is paint. You can do it really cheap with a can of rustoleum. As long as water doesn't get in the tank, and the outside is painted, you are fine.
It leaks at any level of gas when it splashes around in the tank. I can't take pictures at the moment but it looks completely normal. I will try to take some pictures later if I can. About the inside of the tank: I cleaned the inside from rust and a few weeks later the bottom of the tanks looks to have the color of rust on it. Is this something to worry about? Should I put a tank sealer on my other tank before using it after removing rust? Sorry for all the questions.
