I am back to square -1 with my cheapold 280CE euro.

Engine is a M110.984

Problem it does not start. I mean it will not fire or even run for a short time if I put gas or ether or both down the intake.

Was running before, then started running bad and does does not even run.

What are the possible reasons???

heres what I thought of.

Ignition control module ( I have visual fire at across spark plug and a dwell of 30 degrees when cranking with engine)

Some gear on timing chain has jump a tooth ot two. I get no chain noises and distributor is turning round and oil pressure is buliding.

Any other reason??

where do i go from here??
