First, thanx for the quick response. The engine is a 2-stroke glow engine. Do not know which series, etc. it is.

My lost muffler engine has the bolt holes spread apart 34.5 mm and I have a second ASP .91 that has a muffler mounting bolt hole measurement of 43 mm. Not even close.

If anyone has a muffler with a mounting lug hole spread of 34.5 mm, I'd sure like to buy it.

Thanks.
