Hi ,
I have an OS Max FP 35 and an FP 40 (stock)and was wondering what ( if at all) kind of mods can be done to these engines to make a good C/L motor ?
The 40 has the letters "GR" stamped under the exhaust side motor mount .
Any ideads of what cylinder / piston combo it might be ?
What would be the proper fuel ratio to use for these motors ?
Thanks in advance
