I'd like to replace my Champion plugs with something that is less suseptable 

to fouling.  I don't know whether I should go with just a new set Champions, 

or perhaps Iridiium plugs or another type.  Any recommendation from Listers 

would be most appreciated.  I'm flying a -4 with an IO-360 with Lasar 

ingnition.



Thanks,

This is sure to start another mogas war, but here goes anyway.  I use 

mogas in my Pitts (O-360-A4-A) so don't have the fouling problem.  The 

cure on lesser engines is the REM 37BY, but I don't know if they'll fit 

in the O-360.  They were designed specifically to target the lead 

fouling problem in the O-235s.  I'm assuming that your fouling problem 

is lead, and not oil! 



The other cure is to lean the crap out of the engine at all times ..... 

from startup to shutdown.  At any altitude.  I know, that's not what 

Lycoming recommends, so don't waste the bandwidth busting my chops. 

 Leaning agressively, like mogas, has worked for me and has for years.

Excellent suggestions assuming the cause is lead fouling.  Another

one that has worked for a lot of people is to use a lead scavenger

like Decalin TCP Plus.

 Just switch to the REM37BY.

 I can tell you they work fine in my O-360.

The REM37BY are approved.



If you want more plug details, Lycoming has their approved spark plug list on the web at



http://www.lycoming.textron.com/support/publications/maintenancePublications/serviceInstructions/SI1042X.pdf



On my Grumman Tiger (O-360-A4K) I just do a spark plug clean every oil change.. if you buy the plug sand blaster tool - cheap at Harbor Freight - it's easy and quick.... better than waiting for a lead blob to give you a bad mag. check....

Gary, any idea how these would work with a magneto ignition?  My IO-360 on my -4 fouls the bottom plugs really easily, and have to be cleaned every oil change in order keep them running well.

They ought to work just fine with mags.  I run  UREM37BY plugs with my Slick mag on my IO-360-A1B6.  Bottom plugs.  I  have yet to experience a fouled plug in more than 1000 hours.

  

 Granted, I have a Lightspeed Plasma II firing the  top plugs, which must help...but at least the UREM37BY plugs on the bottom  haven't had any issues.

Best place to get them?  Anything special that needs to be done for the gap?

Vans sells them.... keep him in business....   

His prices are good too..

PS  the Unison ones are shorter than the Champions, and allow a shorter (cut-down) socket... making easier removal on #3 and #4 where the side baffles are close.

Sky Geek was cheapest last I checked.

Yeah...  Dan... but.....



Sky Geek is only 5 cents less than Vans.... 



I'd rather keep Vans in long term business than Sky Geek....

 Paul-

  

 I am running the REM37BY plugs with standard Slick Mags.  Just  gap them for .019" and they still won't foul like the old REM38E or REM40E  massives.

May have all info you need. I have Irridiums I put0 in year ago, I burn mostly mogas, so cant say much about lead exept that when I0 do burn some out of my left "takeoff" tank I have no fouling. They stay clean as0 a whislte all the time. They are expensive. Charlie0 Heathco
