Spark plug for two stroke generator

[Chevy454z71]

I have an Eastern Tool and Equipment (ETQ 950/TG1200) air cooled two stroke generator that is available from a plethora of manufacturers as it’s just a cheap Chinese one but they are all the same basic machine. The owners manual for the specific model I have says to use a NGK BPR6ES spark plug. While reading around the web I found an owners manual under the Champion Power Equipment name and that recommends three different plugs (heat range is different) depending on ambient temperature and use. I also found under the Tail Gator name to use a different plug than the four already talked about. Would it be of any benefit to change the plug according to the temperature or use?

I think @Chris142 has experience with these and knows what plug works good in them.

No. Champion sucks. NGK is better.

NGK makes an iridium plug for that application, part number BPR6EIX. The colder plugs are, of course, BPR7EIX and BPR8EIX

Denso makes a twin tip iridium, part number IW20TT (same heat range as stock NGK BPR6). Denso doesn't seem to offer the TT in the colder heat ranges

I have a few of them I just run the recomended ngk plug. They don' t run very high rpm and spooge a lot of oil out the exhaust. I recommend 64:1 once broken in.

NGK good. Torch bad. Like, maddeningly marginal. If that came with a (legit) NGK, good on them!

Are you sure your machine is 2-stroke. Says oil type is 10w30?

Yes, look at the pictures again.

Yes, look at the pictures again.

That’s unbelievable

I need a few rubber feet for one of these and a carburetor!

 

[Chevy454z71]

That’s unbelievable

The Chinese don’t care about their equipment and use whatever they can get.

For small engines, I have always used and will continue to use Champions. I never had a single issue with them.

Appreciate all the advice on brand but am wanting to know more about the heat ranges and ambient temperature/work load.

Use autolite #63 or #64 and crossover to ngk. Those plug #'s are so close they crossover.

If you’re cornered go to a 7 NGK

It is a 2 stroker!

The only reason to go hotter or colder is fouling or other plug failure modes.

If your running high RPM / high load you may benefit from colder.

If you run sparingly or low RPM run hotter.

Only way to know is put recommended plug in, use it as you plan for a while, then check the plug visually.

I have never had a plug problem in one of these generators after ditching the Torch plug and going with a name brand that crosses over to it.

The heat ranges on the plugs he mentioned are all very close and even crossover.

Use the stock heat range to start, and if you have any problems, remove the spark plug (the type of wear can tell you some things), and use a different one (hotter/colder) if necessary

How often are you going to use it, and under what conditions?

I’m going to run a small deep freezer with it on a three day road trip, it will be in the bed of my truck. After that trip I don’t know when I’ll use it.

Get the recommended NGK plug, and a spare. 3 days isn't much even if it were running full time. After you trip check the plug and see how it looks.
