you know that OS has a dual plug head that they sell in Japan?</FONT>

Funny how things come around. </FONT> <BR><BR><FONT

Dual plugs<BR>>
anyone?http://www.rcaerosport.com/articles/reviews/evolis/crino/e10.htm<BR>(I<BR>>
remember my very smooth running dual-plug Merco 60.)<BR>><BR>> Also
another 2-stroke memory... the great Webra slide valve carb. Mine<BR>>
seemed to give INSTANT RPM up from an all-day idle with my stock
single<BR>plug<BR>> Webra black head engine! It had almost zero spool-up or
spool-down time to<BR>> or from any level(s) I chose. Blip...blip...blip
<happy smile>. Once I<BR>made<BR>> an adaptor and tried the slide
valve with a ST blue head. Same dynamics.<BR>> Also gave more HP than the
stock ST carb. Just some thoughts.<BR>>
