I've ran so many p5's and p5 copies over the years, something about this mito carb has me intrigued makes a little more run time and is easier to tune.....if you are having any problems reset the needles to factory settings ....in my opinion the mid range is super sensitive use half hour's if any ....
What type of fuel / % nitro are you running ?
Also which plug are you running ?
I believe it came with the C6TGC, which is what I've been using. I also picked up a C5TGN since AMain's website says it can be used in any temperature range but have yet to use it. Also picked up a CTO7, thought I might try colder plug since I live in Georgia and we have Very hot and very humid summers. Any suggestions on best plug for this engine ? I haven't been able to get the tunning down perfect yet, I think I'm missing something once I start trying to tune my low speed needle and idle screw, my car feels a little sluggish coming out of corners and on the bottom end, I noticed most other buggys on the track were pretty quick and snappy through the corners. In the main event of my first race, my engine kept dying every time I would land a jump, & I have yet to figure it out. I'm running it in a tekno nb48.3 with the stock 15t clutch bell
