So, I added another hole in the governor arm, and it pulls a max rpm of 4800 now, and hits the governor. Only pulls 3600 rpm under load, but is jetted a bit rich for a header pipe, but still have the factory muffler on it at the moment... Gave it the first shake down run today, need to make a...

Correct, no load...

Um, idle, not working rpm... 1800 +/- 50 (when all else fails... I looked in the book)

So I finally got it fired up today sitting in my mud motor chassis. The little tach (once I finally got it to read rpm) said my max rpm was 5200, and then the governor kicks in and chokes it back. Tomorrow I will be adding another hole, slightly back in the governor arm and see if I can dial it...

Not even close

Mine has a hole factory. I'm gonna try it for the time being....

Hmm... Now that is a new idea, I had not thought of... Who makes a rpm limited coil? That sounds like the clear ticket!

Non Oxygenated is all I run in all of my small engines...! Made my neighbor switch too, as i told him I was done fixing his carbs!

Governor, 5+ years, good enough for this guy! It will probably only get used 6-10 times a year (effin MN winter, slams the door on fall hunts pretty quick) Motors are cheap. If I like how it performs, perhaps I buy and build another new motor in the off season

If a guy keeps it under the point of floating the valves, what would be the cause of damage? (And thats a serious question, as I don't know) I honestly wonder if a slightly warmed up 212 would have the nut to hit the higher rpms under the prop load pushing a 1236 duck boat with 2 adults and gear...

I am going to put a tach on it, and watch the rpms. Its going into a mud motor kit, so im not sure under load, if it will ever achieve the higher rpm. Will be a bit of a test, and will have to report back with my findings. I'm not opposed to more upgrades, but was trying to keep it as mild as...

So I finally pulled my new motor out of the box, and it has that hole already in the gov arm! Rest of my parts will be here Wednesday...

Awesome! Thankyou very much, this is exactly what I was not having any luck trying to find!

I guess it really comes down to me removing the throttle screw, and playing with the governor spring a bit. Somethings in life just never seem to come that easily

Thank you... I have watched about every video I can on YouTube, and 99% of them go to eliminating the governor. I read most of that sticky, but must have skipped the bottom! If this was a sbc it would be easy, but the simplicity of these little motors, have me scratching my melon...

Hello guys... The motor in question is the typical HF predator 212, non hemi, brand new, but the application is a bit different. This one is going to power a mud motor for my duck boat. I want to increase the rpm, while keeping the governor for safety precautions. I'd like to turn around 45-4600...
