How Do I Break It In? HELP!

[KartRacer695]

Hi, I plan on buying a PowerFist 6.5HP clone form princess auto any day now, but I dont know how it should be broken in properly. I have bought this engine before and have sold it since then.

Any recomendations as to what Oil I should run?

Anything about spark plugs?

any tips on how to break this engine in would be wonderful.

Thanks

-Jay

No break-in required...unless it was built 40 years ago.
Use the recommended oil. It's in the manual.

Start it, set the idle, when it suddenly speeds up(this is the rings initial break in) reset the idle and go run it hard, constantly vary RPM for that whole tank of gas, then change the oil and use it normally. Use good oil, I used to use Castrol GTX but BP owns them and I refuse to support those *******s. Shell rotella T diesel oil(made to higher standards than gasoline oil) is supposed to be really good and cheap stuff for just about anything internal combustion.

I beg to differ Russ.

From the HF clone manual:

Break-in Period
Breaking-in the engine will help to ensure 1. proper equipment and engine operation, and will extend the engine’s lifespan. The warranty is void if the engine is not broken in properly. The first 20 hours of operation is the break-in period.

During the first 3 hours of use:
• Do not apply a heavy load to the equipment.
• Do not operate the engine at its maximum speed.

After the first 20 hours of use:
• Change oil.

Best procedure is to fill with regular petroleum oil, run with a load at about 2500rpm for 20min then drive gently for another hour or so. Change oil (should have a gray/silver discoloration) and put synthetic 5w30 in.

break it in like you ganna run it is what ive always heard and always did.

Change the oil pretty regularly and use good name oil. You pay for what you get.

Run the crap out of it . If you bought it brand new, thats what a warrenty is for.

If you didnt, everything said above is the proper way to do and not take a chance and blow it up.

HF Clone oil

My hf clone manual says to use oil without any additives. That seems crazy. They can't mean use non-detergent oil can they? I used non-detergent oil one time in my life and it immediately ruined my ring seal. I want to use Castrol GTX 10-30. Is this ok?

Differ all you want. I speak from true life experiences. What is your experience?

Im just saying there is supposed to be a break-in period. Not that using it normally out of the box will screw it up.

Never broken in an engine and never will. They load test them at the factory, thats enough.

 

[Doc Sprocket]

Okay, fine. Let's try this- Would it hurt to go through a break-in procedure? I doubt it. Might feel better.

its more important to brake in a new two stroke than a four stroke, there only cheap Chinese engines (clones) and do you honestly think townies (no offence intended to anyone) brake in there new mower, i think not

It says to use a multiweight oil?

 

[DirtTrackRacer_07]

definetly use detergent oil

It will clean everything up in the crankcase and get rid of the factory oils.

I dont see no problem in running castrol 10-30

 

[KieranM]

dont they have machines to clean the crank cases in the factories??????

 

[DirtTrackRacer_07]

yea but they put oils and greases on them to keep them from rusting while they assembling them and when they are sitting like in a store.

I would wont to get something in the crankcase that would lubricate well and do well with heat

The factory oils they put on the motors are cheap
