Hello everyone,
I would like to ask you about my problems with 80cc engine I have.
I am trying to break it in properly, as instruction says. I use 1:16 semisynthetic oil mix with 95 unleaded gasoline.
Problem is low top speed - about 20mph(30km/h). Engine starts four stroking above that speed. Second fact is that spark plug was dark and moist. Beacuse of these two things at about 60 of mileage i dropped needle in carbourator 1 notch up to position 2 to make mixture a bit leaner. Now, at 150miles it runs little faster but still starts to four stroke at given speed. Spark plug looks better, it's cleaner, but still little dark.
My question is - should I set the needle to middle- factory setting and finish break in perioid, and then start to think about tuning? I am afraid that engine is being damaged beacuse of leaner fuel-mixture, so it has worse lubrication.
What should I do?
