Re: Question about my 1988 dt115
Check around your water intake too if the pee (telltale) hole is not blocked. You may have to take outer intake screen off. it's not hard.
If it's not blocked, you can also try blowing compressed air with a basketball needle attachment on your compressor nozzle up the pee hole (on your motor that is) insert it all the way.
Let us know how it turns out.
