Hi all and thank you ahead of time for any help you can give me. Just picked up a low hour mep-803a and did the usual maintenance on it. Started right up and I noticed some fuel leaks. It was just some loose injector bolts. I did buy some new fuel lines as well and will replace them. However when it runs it seems to be running way faster then 1800 rpm. I tried the hertz adjustment but seems to do nothing. I even changed the factory stops and no change. The hertz meter is reading 65, pinned and once in a while it goes lower but right back up again. It smokes quite a bit as well. I have put seafoam in the tank as well as some have mentioned. Just don’t want to let it run for very long under the circumstances because it heats up pretty quickly. Any help or suggestions would be appreciated. Thx again.
