I purchase a used Dynamite 29cc engine on ebay and it's running in my Losi 5ive T very nicely. While surfing the web, it occurred to me that the engine I'm using was pulled from the Losi XT truck that uses the Dynamite 29cc engine...but with 40:1 fuel oil ratio.
My question: How can there be such a difference between fuel oil ratios for the same exact engine but on different vehicles? It would be significantly easier for me to simply use 32:1 on all of my engines since that's what most RC airplane engines use, but I hesitate to use anything other than 25:1 on this engine until I figure out WHY the new Losi monster truck uses the 29cc engine with 40:1.
