noticed a very strong gas oder and found no leeks but found gas oder in my oil...could it be the flote stuck...also oil in breather filter...I believe the oil in my filter is just blow back..

Sounds like either stuck float or a needle/seat that isn't closing off/sealing completely. My riding mower has that problem so until I can fix that I've just put a shut off on the fuel line. It runs fine and doesn't flood when running but if I don't shut the fuel off the tank will drain into the engine in short time.

kind of thought that could be the problem..im taking the carb off now so I can check the needle valve and clean the carb..before I change oil. just need conformation before hand...thanks.

On the needle valve, look for a small ring worn into the end of the needle. It can be a very minor ring and still allow this problem. When i fix a cart with fuel in the oil, and find Any ring on the needle, i replace it. 98% of the time, that solves it. The other 2% is mostly attributed to fuel pump problems and carbs that have been previously worked on with a 1/2" breaker bar

installed a new carb because the old one was broken where the float retainer pin goes...it was causing the float to stick..

Good that you found the problem. Sometimes fuel problems can be the worst thing to diagnose. At least when your working on a fuel problem.

Working on a wire problem, it's the worst. Ect. Ect.

The worst problem by far is the infamous "ghost problem", it will never repeat itself if i am any where near the cart to see it.

I have the same problem and last year I replaced the fuel pump, fuel filter, lines and a new carburetor. Carb was an aftermarket one.
