"1991 yamaha 225hp ob. Engine
"1991 yamaha 225hp ob. Engine performs flawlessly except @ 3500 rpm.If you ease it up as soon as it passes 3500 it's absolutely perfect again. It has a intermitten fire only @ 3500.It's not a fuel issue.. I believe. it can run up to 3400+ perfectly & 3600 to top end flawlessly, idles perfectly, no sneezing,spitting, caughing thru carbs, timing is right on, I'm leaning on the cdi, some kind of electrical issue.changed the tps (failed ohm test)but oviously still not it."
