Hello all,

I have recently had the opportunity to pick up an old 140 that's been in dry storage for a number of years. The first thing I've tried to do is get the engine to fire (after putting on some SU HS6 carbs that I know are roughly tuned).

I don't trust anything that comes out of the fuel lines (I'll drain the old gas out eventually but now I just want it running), so I put some fresh gas in the float bowls and turned it over. It fired up but there's no throttle response, I mean literally nothing happens when I change the throttle position. The engine holds a low idle, just barely (approximately 600-800 RPM)., but will not rev higher.

I checked the timing by rotating the crank to 5 degrees BTDC, as it says in the manual, and the points are just starting to open on the number 1 cylinder, so I know the timing is at least roughly correct (and it was running when parked, the previous owner drove it to the storage. There's no real reason for the timing to change much with time).

Any ideas?
