Anyone know which Novarossi plug fits an RB R3RC?

Also, I'm running 25% fuel, which plug should I be using?

Also, how often should I change the conrod? I know I got the conrod from Murnan but it was a Nova rod and I don't remember which one.

You need the Nova 7601 conrod. Only replace it if it has slop in it, pull the cover off and turn the crank so the piston goes to TDC and then turn the crank back and forth to see if there is any play between the rod and crank pin.

Anything else needs to be replaced when replacing the rod?

Check the front bearing for air leaks. Block the carby air inlet and exhaust outlet, connect a bit of fuel tube onto the carby fuel inlet. Then get some very soapy water, brush the soapy bubbles on to the motor and blow into the fuel tube. If the front bearing is leaking, put a new one in. At the same time check for air leaks around the carby base, etc.

Also check that both the front and back bearings are spinning freely.

almost every high end .21 onroad motor ive owned had a tiny leak thru the front bearing? also as for the rod, change the first one after a gallon, and go from there every gallon sounds like overkill a bit to me, but who knows, i would think after first swap out, i usually go every OTHER gallon...

I ordered a replacement rod for my R3RC (Nova 07601) and I got a Max Power 07601, didn't think anything of it. I put the rod in, put piston and sleeve back together, and it doesn't turn over. The rod gets to the bottom of the case, and gets stuck. I took it back out, and measured the width. The Nova rod is 4.18mm and the new Max rod is 4.21mm. Now the person I ordered it from is telling me they are the same. I'm sure they are supposed to be, but i'm looking at this one and tried it and it's obviously not the same. Anybody know why this would be so off?

I replaced the rod after break in with a Nova 07601 and it worked fine. this max rod is not working.
