Man that sucks after all that work. My motor is still running great but I have it rev limited to 5200 rpms. Sent from my SM-G930V using Tapatalk

Thanks BWL

Here is a pic of my rig I run 21mph with me and gear but add a 2nd 250lb guy and drop to 16mph. I am going to add 1.3:1 rockers

The engine in the picture is not a hemi are you doing a separate engine

I am about to order the rockers and guide plate. Should I upgrade the carb as well. I am running a stock carb with 36 jet and 140 E tube. Also with the 1.3:1 rockers will I need different push rods

Do I use the same valve lash of .003 for these rockers

Should I do both rockers or just the intake

This motor is being used as a longtail mud motor

Will adding these rockers increase my torque. If so at what RPM range should I expect more torque. I have done a few mods like installing high flow air filter Robertsons torque tube 18 pound valve springs Billet flywheel rejetting carburetor and removing governor. After hunting season I will...

I like the .036 jet

I would change the air filter rejet the carburetor and added Robertson's torque tube

Hey black Warrior I just finished my setup I am running 21 mph with myself a pop up Duck Blind and hunting gear and I only need to turn up 5200 RPMs to achieve this speed with a 6 & a half inch prop

Thank you for all your replies the engine runs fine. I installed it on a longtail as Mud Motor and ran it this weekend for about 3 hours. That little motor has some juice it pushes my 12 foot flat boat with me and duck hunting gear 21 miles per hour.

Okay thank you I was just curious as to what was going on as it did not happen until I change the flywheel. Could this be happening due to new flywheel firing sooner than stock flywheel.

The cough only happens if the engine does not start. Also this only happens on a cold start up. Once engine is warmed up it starts immediately.

Sometimes on Startup engine coughs through intake. But once running all seems fine. Never had this happen until changing flywheel to a Billet flywheel. The flywheel is 8 degrees advanced timing and 32 before top dead center. Do I need to change the cam or is the factory stock cam okay. This is a...

Thank you to all that replied I will get an NGK plug and check it after a few hours and let you all know the results

I did not know that but I am new to this and it is my first build. I am going to buy another predator212 and build it to a stage 4

I have not checked to see if the spark plug is still dark after changing flywheel would the advance timing cure the problem

I installed the Arc Billet flywheel that has 8 degrees advance built-in
