these nitro engines are alot like 2 stroke dirt bike engines..especially the old air cooled ones...basically the same concept but a different way of going about it be it fuel and ignition...if you have ever been around dirt bikes you will notice that on like 250's and under they start much easier if you kick them fast at about half the travel of the kickstart...I say 250 and under because my friends 490 and my other friends 500r kick so hard that you pretty much gotta put all ur weight in it to just get them to kick (especially if your a smaller guy like myself)....also if you talk to anyone that knows anything about dirtbikes they will tell you not to run them wide open for a long period...I beleive this is also the case with these nitro engines...

I know this post is off topic...but the reason I made it is so people understand comparing these nitro engines to 4 cycle engine (car engines and such) is like comparing an apple to an orange....

landslide this post wasnt towards you bro....just wanted to point out the simularities and have seen many people compare these engines to 4 strokes...lol
