hi! whenever i drive my quadzilla rl500 through mud or water my buggy cuts out!! also if im driving about 35-40 and when i press fairly hard on the brakes it cuts out and wont restart too easily! could someone tel me whats wrong? thanks

do you normaly have to press the brake pedal down to start it? if so then the switch could be dirty. also check the wires running down by the brake pedal

okay pilot thanks il check both of these!

i found out the problem!! actually there was 2 problems! both to do with not enough petrol getting to the engine. the 1st problem was that the fuel filter from the petrol tank to the carbretor was the wrong way around and the 2nd problem was that the cap under the petrol tank to leave fuel out was all blocked!! i bought the buggy with fuel filter back to front, so the buggy was built wrong!
