Hey every one,
Im changing fuel brands and am thinking about running 30%
I am running Byrons 20% with a Mcoy59 Plug. If i go to TQ 30% what plug do i run, as in hot or cold? Im running a O.S. .18 not moded.

It should run just fine with the MC59 plug, you will need to retune the engine anyways, will usually need to richen the mixture when switching to a higher nitro content.

You must add 1 headshim of 0.1mm

IT'S USUALLY BETTER TO RUN A COLDER PLUG WITH HIGHER NITRO CONTENT
IF YOUR JUST BASHING YOU SHOULD BE FINE,BUT IF YOUR GONNA RACE TUNE THE MOTOR I RECOMEND A COLDER PLUG,AND YES YOU DO NEED TO ADD A HEAD SHIM,REGARDLESS WICH PLUG YOU USE

RACING MASON

How do you know what size shim tou use? Is there s standered chart or somthing i can download?
Thanks for the info

you should be fine using a .1mm shim if you start to blow plugs go to .2mm
hope this helps
