I can't say if they are any better. Have bought 6 engines (1 Skyhawk) and really can't tell any difference. They ALL have problems, but I minimized mine with the mods I make. Had 1 coil go out within 3 days, had a blown head gasket, and had a replaced defective head gasket trash a piston/jug. All with the first engine that I installed OUT of the box.ok that helped out a bunch thank you very much i have a skyhawk engine are they any good or not or do they have alot of problems also read reveiws and they where good for say
So what is your problem, you stated "80cc silver slant z80 will not run HELP PLEASE" No spark,no fuel, no compression what? A little more information would sure help.I have a bgf engine thats almost a year old with no problems whatsoever. I know my engine has crankshaft ball bearings and connecting rod piston wrist needle bearings. problems I have had were idle screw spring wearing out and moisture getting under my magneto cover and frying two ignition coils. Red Permatex solved the moisture issue, and a small section of fuel line held on with a cable tie keeps my idle screw from moving. also had a problem with an air leak in my carb when I first got the engine. carb o-ring solved that. gonna clean my spark plug soon so I can do a proper color test and make sure my fuel mixture is right. I think it is, but I want to be sure. I want this engine to last at least another year.
