I'm on my 3rd HS 142 engine. 1st one con rod bolts fell out[covered by warranty] 2cd HS I screwed up[broke a exhaust stud flush with engine] 3rd HS is about 5 months old and has stopped running. Good compress,valve clearance is right. all 3 engines had a common problem ---carburetor---On all 3 engines i cleaned the gas tank and used a in line filter. All three engines would run fine for awhile before developing performance problems which seem to be carb related.hard to start, hesitation and flat spots on acceleration. All three engines have been running on gas with 10% ethanol. is ethanol the problem?
