Hi, I'm currently trying to get my 1980 CX500 to run after being stored for about 10 years. It was previously running well and has only done 10,000 miles from new.
I have good compression and spark. Clean air filter and new fuel.
I discovered that the carbs were clogged with dried petrol residue and hard varnish like material
The carbs are now cleaned and jets are clear. The pistons and needle valve were also stuck but are now clean a moving freely. Both float/float valves are also now working.
I can run the engine for a few seconds and rev it, using "easy start gas" through the carb air intakes. It also runs (badly) on full choke for a few seconds but if I touch the accelelerator the engine stops.
It doesnt fire at all without choke.
Have I omitted to clean something perhaps? Any ideas would be most welcome. Thanks, Bill
