While taking apart my elan yesterday for an unexpected and undesirable mid Winter motor surgery operation, I found about a tablespoon of gas sloshing inside the muffler. After a few minutes of it dripping out a the correct angle I left it to evaporate. Anyone else ever experience that?

Never fun, but nothing you cant handle Rock! If I had to guess - getting unburned gas into the exhaust is a symptom of cranking it over lots without it starting. The carb is doing its job well, and maybe even flooded it a time or two without it running right since. You likely had / have spark problems that you are fixing, hence the plethora of fuel that had to go somewhere. Probably lots in the case too. I've worked on engines before that didnt have the muffler on and in that scenario I've seen plenty of unburned fuel ooze out the manifold. THen it blasts everywhere once it starts lol.

Makes sense that is unburned fuel. I have been cranking it over a bit diagnosing a few things. I'll have to see about draining the case if I can without too much work. I think my 299 engine has a drain plug??

Oh ya if you think it's got a pile in there then pretty much all singles have a drain plug at the backside near the tunnel top. Just a short bolt with a copper washer on it - don't overdo it cranking it back in. I'm sure you're supposed to replace it... but I never do and never had a problem with leaks. Most old twins had two drain plugs also, but I think they might be on the front. Got a 50/50 chance on that lol
