another fuel question

[white329]

Have a question about nitro fuel. Having trouble keeping engine running. I can prime fuel by blowing into fuel line at the stinger, it will start and run for a couple of secs. I noticed there is some white build up in the fuel supply. Does nitro fuel do that? Thinking the carb is plugged up with the white junk. What do u guys think? Thanks

If you have some sort of build up in the fuel then its bad. There shouldnt be any type of film built up at all. The fuel should be clear or tinted orange red or blue depending on brand but never with a milky film. Get some new fuel and also you may need to pull your carb apart and soak it in new fuel or wd40 and clean all the needles and seals then see if that clears up your problem.
