Wow. Smooth presentation (no ums,ers,ahs), lots of light so you can see what's going on, subject covered effectively.I have used some other youtube videos for car maintenance and repairs but this is my first foray into rings/pistons and stuff like that. I think I got lucky and found a good source right off the bat. Will look for your other videos, thanks!

Awesome job ! Very informative and broken down with perfect directions. also, the lighting thumbs up!!

what is I very love this men.is so easy to understand what him doing....very nice the voice is clear....I like u...keep up .......A+A,+

Finally you covered the problem that I had, which was the ring gap and the degrees apart. I needed to actually see it. Of course I’m a 14 year old boy building a stage 2 predator on my own sooo.

Can you change mines on my 2003 Mercury Marauder? Please

If you leave the connecting rod and just pull the head off how do you compress the rings to slide the head down. Saw this done in another video maybe that’s not recommended?

I replaced the piston before all by hand, I'm not sure how. I have a 38mm piston that I'm trying to get in the bore. It's for a German moped. The only piston compressor I can find is $25. That seems like a lot of money for like 1-2 uses. I'm going to try and use 1.5" tubing instead and makeshift my own compressor. I'll let you know how it goes.

Do the gap ends have to be 120° apart or does it just have to be away from each other?

@KartFab

Do 120 for install, rings end up spinning anyway when running

Does it mater the piston orientation in the block ? Mine isn’t marked ! Some I’ve done had markings , an arrow or a line or something , this one isn’t . It’s a HSK70 Tecumseh .

Check the tecumseh factory service manual. Also check underside of piston. Some have no marks and it doesn’t matter which way.

What type of oil do you use in the piston and rings?

@KartFab

4 жыл бұрын

Any oil will do with a mild build. Typically 10w30 for above freezing and 5W30 for freezing temps

If there is a gap between piston and cylinder wall that will cause no compression correct?

How to understand piston Ring depreasation

Once I upgrade the connecting rod, piston, flywheel, camshaft, etc. will it be safe to remove the governor and put the engine through hell of a high rpm?

@KartFab

yup. I doubt you can get it to a super high rpm without doing a lot of modifications for flow, getting timing just right, and having a wild cam with upgraded valvetrain.

Hey, this is my brother's account but I only expect to get 6300 rpms, as that is what the fillet flywheel, connecting rod, performance piston, performance camshaft, upgrade valves and valvesprings can handle. I am trying to do this to a Predator 670cc and place on an insane off road go kart.

@KartFab

Also, IIRC there isnt a huge selection in performance parts for the predator 670cc. I do know that the honda gx390 stuff would fit the honda gx620 etc, but you would have to do a lot of research to see piston size, rod length, rod end sizes etc in order to figure out what to get for the predator. If you do the math, it is actually cheaper to get a decent used motorcycle engine with insane hp for a lot less than hopping up an engine like that.

Good job
