I have a honda 250 r it is getting gas and spark but wont run. it keeps fowling the plug. so i replaced the plug and the same thing. it doesnt even try to fire not even on carb cleaner
Reed valves bad, Carb gummed up, tank full of rust, lots of possibilities. Have you checked for compression with a guage? What is the condition of the 250R?
fuel oil is fresh I do not know of the condition of the carb but got it to fire on carb cleaner about a month ago and when i finally got to it again it did what its doing no i have not checked the compression and the condition is ok it ran about two years sgo it is a quad
