Welcome to the forum, glad you joined us.

Have you had it running before?

Try to disconnect the kill switch and give it a go.

how long did you have it?and how much did you use it?

I your getting a lot of product out of the exhaust pipe carb bowl over flowing? Need more info.. What is your fuel/oil mix? Does it have spark when you ground the spark plug to the head and turn the motor over? More info please..

Hi, I think I have the same problem as him. When i try and start the engine, all I feel is the vibration of the piston moving up and down with the occasional cough. There is also a bit of blacky brown oil leaking from the exhaust.
I have checked and I am getting a spark.
I have not started the engine before, i have just installed it. I am using unleaded 95 or something rather with 2 stroke oil.
Any help would be appreciated. Thanks


I just went and rolled down a hill with the clutch engaged, the engine was noticeably warm suggesting that there was combustion.

Check The Fuel Mixture. If Its Not Broken In Use 16:1. Check The Carb For Leaks Around The Intake Manifold. Use A Ngk Plug With Proper Gap + Use A Better Plug Wire. If Its Dripping Oil From The Pipe You Probably Got To Much Oil In The Gas. Hope This Helps
