It ran last about 2.5 months ago compression was checked about 3 weeks ago it was 150 Is there anything to check or do get it to crank just want to crank it on trailer a few secs. Starter fluid or any ideas it has new plugs in it too. Does this happen when the gas cockpit is cut off a length of time?

Re: Need help cranking a older speedster 720 engine
The 3 things that you need to check is good fuel to the engine, strong spark at the spark plugs and compression in the cylinders. If you have these 3 then its time to check rotary valve timing.SBT Tech Support is here to help with your problems.
