ZDZ 80 Hard to start
Hello, I have an older ZDZ 80RV, copper head version, and lately I started running full synthetic Mobil 2T. The engine was easy to start before I started running this oil. Now the first initial start of the day takes a lot of flips. I first fill tank, then power on, not ignition. Choke full, flip prop about 5 times. Ignition on, flip till I hear a pop. Then choke off and flip till it stays running. This use to work good, but now I never hear the pop with the choke and I end up flooding the carb. So I have to let it sit and just flip and flip till it finally fires. Any ideas? Do I need to adjust the low speed? Maybe a different way to start these engines?
