MBX-7R
Keep-Off 21-4
9901ss with 41021
I had the 6mm restrictor in the carb, I have now swapped to the 5.4 but haven't run/tuned it yet. The motor has about a gallon and a half through it since new.
Doing a search in this thread, there are some old posts with guys getting 10-15 minute run times, I am nowhere near that.
If I do stick with the 5.4 restrictor, what should my tuning strategy be to start? Just lean the crap out of it?
Thanks in advance.
going smaller on the insert doesnt always mean more runtime. Drake runs a 7.5mm restrictor in his MBX7R. Everything makes a difference with runtime... Fuel, glow plug, pipe, header, and most importantly... vehicle. You take the same motor and install it in a losi vs Mugen. Guarantee the Losi has way more runtime.
