BME 50.

I store my models in the house. I've heard all the lore about draining the tank, capping off the system, etc., etc., yielding no odor. That simply was NOT my experience with a gasser helicopter some years back, and the basic plumbing is no different on these planks.

My gracious wife would have my stuff in the back yard if "my" room (and soon after, the whole house) suddenly began to smell like the utility room where we store the weed-eater, blower, etc.

A conversation with an experienced gas guy last night suggested I might have a pin hole in the carb diaphragm. Again, I simply do not know enough about these things, right now anyway, to do any more than look for the obvious. And I simply do not have the patience right now to do a serious trouble-shooting job, guided by telephone/e-mail conversations. I imagine that the intelligent thing to do is pull the engine out of the airframe and send it to Keith. But I've BTDT with a YS; it ran perfectly for them, ON THE BENCH, and while they were diplomatic about it the attitude was I simply did not know how to handle an engine. Well, it ran great on the bench for me too. It was in the air where it displayed bizarre behavior.

IOW, I don't want to be told 'it ran fine for me', when my conditions are not being duplicated. Hence, the option of taking the thing to him, still mounted in the model, with my fuel mix.

When my main flying buddy gets back into circulation, I'll be motivated to to fix the problem. Right now, I just don't even want to look at the thing.
