OS .21 VZ-B V-Spec
Hello
I'm new to Nitro vehicles and picked up a used MBX5T with an OS .21 VZ-B V-Spec engine.
Engine looks likes its been well maintained but I am having trouble with it dying when throttle is applied. I think its set way too rich.
I've just downloaded the manual from OS's website and plan on setting everything to factory specs to retune.
Any suggestions/feedback about this engine? I may end up converting it to electric in the Fall but performance of the engine may keep me interested.
Thanks

Bring that middle needle out to flush it's the one opposite the carb slide and then somewhere between 11 and 2 and I bet that thing will fire right up. Don't expect it to last too long. Vspec engines are my fav and i have been pretty much running them exclusivly for the last year and a half but the don't last like a nova or rb. Unless it's completly shot you should be able to get it to run and have some fun with it. When it's cold turn the flywheel completly over and feel when it builds a little pressure does it feel linear or like it slips. If it has a spot where it does not feel linear then the crank pin is prob shot and it will always flame out no matter what you do.
