I can take the oldest Briggs or tecumseth engine and if it has good compression make it run good!
Now having said that I cant ever get a Chineese Knockoff engine to run right. They look good, but a lot of the time I cant even get them too run at all and when they do run they dont run right. I guess my question is what is the main problem with thease knockoffs?
I mean they have compression (60 lbs ) and spark, and fuel but they just dont run right. Are they just cheap crap that one should avoid or is there a fix for them? Im currently working on two 6.5 HSP Greyhound engines. Any help is apreciated. Thanks
To my understanding the biggest problem is the carbs. They are set too lean and plug up easily. I have found that punching the jets larger has helped, but not always. Don't spend a lot of time working on the carbs, as you can get a new one for under $30. Only problem there is that you must buy all your parts at Harbor Freight. Have seen the price of an entire engine at $59.95. Now that is a throw away unit, but people keep buying them and bringing them in for service.
I had supected the carb was a problem because I noticed that the bowl is made of some type of metal that corrodes in a short time and the needle is some type of plastic. I hate too throw them away but I think thats what im going too do, as for I need a engine that will work when I need it, and for more than 6 months without having too work on it! Thanks for the help!
Take Rivets advice on the non-ethanol fuel. The truth is the ethanol is not the problem. The problem is the ethanol loves water. the ethanol pulls the ethanol out of the air, or by any means it can, combines with the ethanol and forms a mild acid. this acid is what causes the corrosion. The major problem is the acid removes the sealant from the carb body, which is aluminum, then the aluminum will keep corroding because aluminum corrodes due to exposure to air. In other words, once it starts to corrode it will keep recorroding, and plug the jets again.
