OS P3 Plug Problem
 
Hey guys,

I got over 5 gallons on my OS Speed. The compression is very good. But I faced a problem for the first time with the P3 plug. The plug was 80% dead in just 7 tanks. I was not running lean either.

Please advise the nature of the problem. Thanks.

Did you run out of fuel on power?

I've had problems with the last couple of batches of P3 plugs . They just don't work but read as fine :nod: I don't know what has happened to them but everyone i know has had the same thing . There must have been a bad batch come through ;) I could be wrong but i tried another brand plug after spending a fortune on the motor and it fixed it .

OS? Issues? No...it's all your fault! or mine, or his, or anyone but OS, they never have issues, and when they do, it's still your fault, and your problem...man I need to let it go, can you tell they wronged me?!

I haven't replaced the rod yet.

I started the my buggy with a new P3 plug and I changed the HSN to 3 which is the stock setting. The engine started right away and after few seconds it shut off. The I changed the HSN setting 2/1/2 and the engine started and after few seconds shut off. There was a loud spinning sound from the clutch area when ever the engine was shutting off.

Idle gap: 1 turn from just closed
HSN: 2-1/2 from closed
MRN: 3-1/4 turns from closed (flush)
LSN: 4-1/4 turns from closed
If your idle gap is not set correctly, you will just chase the tune. set it at 1 full turn , and leave it.. use the LSN to stabilize the idle

Thank you very much for the needle settings.

What are the other causes of a glow plug dieing too early?

to lean, running out of fuel on power, and debris..
does or has the engine backfired?
