Hi Jack,....Unless you're running several engines simultaneously for long runs, I haven't noticed any unpleasant exhaust fumes...I don't run any fuel mixed lube & run the leanest mixer A/F ratio possible for quick starts & clean runs...I Do remember, when new & fiddling with various fuel lube mixes the exhaust smells..I lightly lube the cylinder wall before each run & enjoy closed vented home engine runs without shivers or fumes.....tom.

Saw a video from a show somewhere that had a whole display of engines not much larger than these running indoors, all of them hooked up to a propane or butane distribution system. They were obviously running them for a long time, the owners sitting back in chairs chatting as the public filed through. The system seemed to use camp stove type burner controls to regulate gas feed, and ordinary h and m mixer to feed air. That’s the ticket if you’re a die hard indoor running enthusiast.
I’m interested because my current abode is a second floor apartment with no access to the back yard, so outdoors means fronting the nearby sidewalk, and indoors means clever ventilation and in winter that means it gets cold pretty quick.

"It's just stainless" .....what i thought too, but after trying 5 new various size HSS drill bits without a dent or single scarf curl result, it's been Undrillum so far, but eventually if I gotta use a laser !!.... tom
I wonder if Jin's heat treated it or its somehow become work hardened? Work hardened SS is the only problem I've had when drilling. I think my oiler will be a faux oiler for the time being.

Nice work, Jim...!!!
You've got it dialed in nicely.
And....... You are having plenty of fun with it!
Good stuff, my friend.

I believe Gil has run his for hours at a time indoors. When I went to NAMES they had a few periods of time where the gas engines had to shut down for awhile for the air to clear :D I told my wife not to wear her contacts into the show, but she did anyway because she hates wearing glasses and it really bothered her eyes.

Running much better 8)
Thanks Nick, do you run yours much?
No, not much at all. I play with all my toys in the winter and when it’s nice outside I play with my full size toys instead. I’d either get in trouble for stinking up the house running this in the basement or I’d gas myself out :D
I ran one for about 8-10 minutes in my steam room (door open window closed) the other day, didn't notice any smell. Went outside of the room for a little while to do something and when I went back in the smell was really noticeable.

I'm Still inclined to get a Functional oiler mounted there...My Added main bearing Cap & Con rod functional oilers work beautifully in keeping friction reducing lube flowing, Noticeably extending "miss" time revs & that missing oiler bugs me !! ..The piston O-ring Does respond to manually applied cylinder lube & I'm gonna somehow get a lubricant hole installed....tom.
Its only stainless, shouldn't really be an issue to drill.

I've heard that hard sleeve is a real carbide buster !! Last thing I need is a piece of broke off carbide stuck in my sleeve !!
That's why I've cooled my heels on tackling it, happy with the look of the faux oiler currently and don't think they really need a drip oiler.

Nice job Jim !! Very realistic h & m timing...What spring mods are you using & how did you drill thru the hardened cylinder sleeve to enable the functional piston oiler?.....tom.
G'day Tom, just been going through a collection of springs and trying different much softer ones.
The oiler I made, but is currently not operational as I haven't taken the sleeve out and drilled it.

Nice work Jim , you got it running real nicely, it has an authentic hit & coast cadence just like the BIG boys . great cinematography 😊👍
Thanks Bruce, I'm really enjoying playing with these engines.
