RE: Which Gasser
Unortunately I don't think it will ever sink in. Everyone wants a good engine but, at least in this forum, most want a cheap engine. The auguement then takes off about this or that budget engine and which will perform the best at the least expense. In this case any one of the listed engines will work just fine for a given period of time. How long that will be is not possible to detrmine because there is no timeline data available.
I have Brison, Taurus, DL, RCGF, 3w engines here at the house. I've worked with many, many others at various locations. Bottom line with some of the cheapies is that if they start you'll do fine for awhile. If you want to run them longer you need to pay for a better engine.
