atomik 125 compression

[jev]

Hi,

Picked up a atomik 125 couple of weeks ago and it has a ducar engine in it.
in neutral has heaps of compression but when clutch is in it doesnt seem to have very much compression.

any ideas?

Has a weak spark so thinking coil is stuffed, i'll swap it over with a spare i have sometime later.

that is how the engine is set up, so it can only start in neutral.
when you start it and it's running it will have the same compression

Just how the start in neutral only engines are.
