Re: Help Please on Lightwin Carb issue?

[CHUCK]

quote fleetwin:

Did the engine ever run well for you? , any signs of an internal water leak? You say that it ran pretty well with a different carb, why not just run it with that carb instead of getting another carb somewhere else?

It was a basket-case motor when I got it free a couple of years age. Lots of salt corrosion; I had to pull the cylinder head and exhaust cover and spend a lot of time and effort getting the coolant passages open again. what a mess. I’m surprised it runs at all LOL! But; as you say…the compression is ok …

The water leak issue is I suppose a possibility; the exhaust cover has a broken off screw; there is no external leakage but I wonder if perhaps it is leaking into the exhaust port area? Does anyone know if that would cause speed variation?
The speed variation is most noticeable at medium to high speed. It actually idles fairly well….although the lowest speed happens with the mag lever between SLOW and START…..not over by SLOW like it should be…. (and yes; I have adjusted the mag-plate/throttle synch so it touches the lever when the throttle lever is between the dots….)

As for needing another carb; I have an equal number of Lightwins and carbs. If I took a carb off another motor…then I would need one for that motor…..
