OS vspec... to seal or not to seal?
i know this thread is old, but i've been trolling for information online about the O.S. vspec b/c i just ordered one two days ago. i'm excited and nervous b/c the experiences posted regarding this particular engine are as varied as one could imagine. however, as mentioned earlier, it's the most popular .21 off road racing engine, so perhaps, that explains the variations. anyway, let me ask... what do you guys think about sealing the backplate and carb? i usually don't seal my engines, but for this engine, i've decided to take it apart to clean it, oil it and seal it before running it. so again, if i may ask, do you guys think that sealing an off road engine is a must, given the likelihood that micro off-road engines are extremely vunerable to dirt ingestion if not sealed?
