ORIGINAL: had enough
LOL,
Throw it away?? Rusty crank??
Great advice, when it might just be bad fuel. or a case of him using too cold a plug
Dude,
Try fresh fuel, the right glow plug for the fuel you are using and a slightly leaner than the factory setting,,, and then tune from there.
If you can't getting going seak out someone with more experiance to help you tune it.
A question,
If you don't have the manual, how were you able to set the HSN to factory settings??
Im betting that if he opened that engine up he will find rust covering the end of the crank. and that is stopping the engine from running properly. it needs a servise....
