my friend's 1981 LC350 has been in storage for approx 3 years. It was running fine up to that point. The fuel was drained before storing. We have put fresh fuel & two stroke in, stripped carbs & cleaned all jets/passageways. Fitted new spark plugs. There is good compression & a good spark. However it will just not fire & the plugs are bone dry. Therefore for some reason fuel is just not getting through. The reed valves look ok. I am out of ideas, and just wondered if anybody could think of anything else to try. Thanks
