Predator Carburetor Tuning

OK, so here is my 2 barrel carburetor tuning, I hope it works for you like it did for me.
- First turn both your mixture screws completely in back them both out 1.5 turns each for a baseline.
- Start engine and let it warm up. (engine reached around 2000 rpms)
- I then turn out both idle screws 3/4 turns each, if the engine idle speed started to slow down is the point where you went too far, so I backed up to the previous setting.
- Now adjust the idle speed screw to your setting of your choice (I could only get down to 1300-1200 rpms)
I hope this helps you. feel free to ask questions, ill get back to you as soon as I can.

Sounds pretty good 👍 I just bought The same motor for a six-wheeler I'm rebuilding... A Max 2. Before I purchased it I was getting some pretty good reviews on the motor... I then seemed to come across more reviews that say this motor sucks?? What's your overall review of this motor? Appreciate your time!

This motor will depend on what you plan to use it for, its way over kill for what i am using it for, I could have went with a 13hp/ Predator 420 and had almost the same result but I went full send. I think you'll have better luck in the 6x6 with the big block due to the extra torque you'll have if needed. my only complains are this motor no matter how much you baby it is a pig on fuel with the OEM carb. Also not the quietest engine either, all though I am not running the OEM muffler. I would recommend buying a wiring harness for this as well from Vegas Carts, little pricy but well worth the money due to the plug & play factor. The charging system isn't the best either, I go through a deep cycle battery about every 6 months, but I have a lot of accessories on my cart (8) rocklights, head & tail lights, 400 amp stereo etc. Overall 7.5 out of 10, when I bought mine I think I paid like $720 out the door + warranty but they have jumped in price a lot since then. the carb is a downfall to the engine, maybe look into running a Performance 670 30mm carb set up(would probably help with fuel economy as well) . I cant remember the engine compartment size but I'd run the Factory muffler if you can too. good luck!

Just got mine installed having issues with the engine popping and trying to get the idle down, a little hard to get started as well. What tachometer did you use?

[@connorskipper6934]

Also what exhaust did you use? I’ve got a club car and used the exhaust that came with the kit from Vegas carts. Mine is super loud yours actually sounds pretty quiet compared to mine lol

[@keithellett4283]

I had massive issues with my carburetor when I first got the engine, i pretty much have it dialed in now it’s say 85% . I just can’t let my motor idle for extended periods of time or the plugs will load up. For the tach it should be listed in the video with a link but I believe it’s a Equus tach.

[@keithellett4283]

I used the header it came with . I just recently added a new double layer of header wrap and installed Stringer mat on the bottom of the seat to quit it down and for heat . I’m having issues with my shifter cables getting to hot and ruining the cable after 6 months. Work in progress to find a solution

What is the ideal exhaust temperature you are shooting for?

[@keithellett4283]

mainly going for equal temps among the 2 than ideal.

@@keithellett4283 thanks for the feedback and I will shoot for that.
