I have a new 52cc Mitsu clone trying to break it in.
After a few tanks of 87 gas and 25:1 Penzoil 2 stroke oil running at variable speeds low to about half throttle. Now it is harder to crank it, it feels like it wants to backfire before it even turns no more than 1 or 2 times.
Today I was able to start it once, was runing good about 20 min, after it cooled down, same problem but getting worse.
When I remove sparplug it turns smooth and easy, so the problem seems to be compression or/and timing or what? I do not have experience with small 2 stroke engines besides 2 stroke Ryobi weedwacker which was kind of temperamental, but never acted like this
.
Any hints will be apprecciated as to where the problem might be?
