1999 DF70 four stroke leaks oil into the silencer cover and into the combustion chambers. Plugs oiled up and oil dripping from the iac valve. I have to do a compression check on the cylinders but if the rings have failed that doesn't explain oil up in the silencer and silencer cover. The...
Yamaha s225txrx. Had a lot of carbon built up on the o2 sensor. The motor would jump from 2200 to 3300 rpms without moving the throttle. Also was very hard to start. Once I cleaned and bench tested the o2 sensor and reinstalled, the motor ran great and started right up for about 3 mths. Now the...
The motor runs great above 1200 rpm. Anything below she pops like back pressure in the exhaust and then she dies. Kind of a pain to start have to use the warm up lever to start then quickly back off before the rpms jump up. The gas tank had water in the fuel. So it was drained cleaned and filled...
Ran then sputtered at the dock and now no spark. One thing I noticed the binnacle doesn't have the dead man switch hooked up. One black yellow wire goes from key switch through main harness to motor. The other one is inside the binnacle about two inches long and is going to nothing. There is a...
big jolt almost knocks you down. when increasing rpms to pull out of the whole rpms are steady in the climbing until about 2000rpm. Then it will jump after a couple second pause to 3400 rpm in half a sec. I checked the resistance of the CPS it was within spec on the higher side 228.7. volts...

Starts up and idles fine. When you give it throttle and come back to idle the butterflies stick open just a little bit. RPMs won't drop back down to 850. Linkage is set cam follower lines up like its suppose to. How do I get the butterflies to close they should. Idle stop screw touches the...
engine was serviced 3mths ago. carbs where cleaned twice looked good both times. Motor fires up and will run above 1300 rpm, but anything below it lean pops and coughs out. pulled the plugs which where brand new and they are black and soaked. It has gotton worse in only two trips to the point...
