How common is it to get a bad batch of fuel. I started thinking about this and here is what I have come up with. If you remember my first post when I started having problems I stated that the week before it was perfect during practice and had zero problems breaking it in and running it during a practice session.
I started having problems on race day two Saturdays ago and have had problems ever since. Two Saturdays ago is when I bought a brand new gallon of fuel. In fact I didnt even show up with the last gallon that I had becuase I used it all up during the practice that I had when it ran great.
Since the get go of this new gallon of fuel I have had problems. I also started thinking about my sons 1.0 during race day. I had his buggy set up perfect and it flammed out a couple of times during the races which never happend to me in the past before handing it down. I also had to play with his idle in between races as it was higher than normal. I also had to replace a glow plug in his that was fairly new. We were both using the same new gallon of fuel.
Jaz and everyone else, this could be it. I am hoping that this is the problem but questioning how often this could happen. I am going to order some stuff online to test it. If I buy another gallon from hobby town I could possibly run into the same problem if it is a bad batch. At least this is one other thing that I can eliminate if its not the problem.

I know it was mentioned but have you checked the carb boot yet? pull the motor out and take the boot off and pull it over your finger and inspect. if you have a small pinhole tear/hole the motor does exactly what your describing. Without taking the boot off its hard to check for leaks, and when you put it back on seal it up with some engine sealant on both ends of the boot and zip tie the big end.
cheezy91, you can use a go tech carb boot if your in a pinch, just use some engine sealant on it and zip tie the big end, its a bit narrower on the big end and using the zip tie spreads it out a bit and works fine.I actually liked the go boot a little better than the stock cause its a better and thicker rubber and doesn't tear so easily.
