RE: walbro WT carb question
ORIGINAL: pe reivers
If it is a garden type plug, with conical seat and 14mm thread, it must be an R-type, or the ignitions of Evolution will act up in strange ways.
if it is the new 10mm plug for ICU ignitions that replaces the NGK CM6, it is a non-resistor plug.

I guess I should add I own a DA100 which runs the NGK CM6 but I don't know why it is ok to run.

RE: walbro WT carb question
Okay, here's the latest.
Replaced the ignition battery with a new 4 cell nimh 1200, and put the new plug in. Fresh 40:1 93 octane. Still ran a little crappy but my gasser friends said it was running rich
and adjusted the high and low speed needles and it's tick like a swiss watch (pre-quartz). BTW, pe reivers,
I wish I could borrow you for a few beers to thank you ( and some others at RCU) for all the help you provide. ( then I would drag you out to the field and see if you could get my MVVS .61 to run dependably. I tried 2 carbuerators and 2 headers/and 2pipes, all from from Morris Hobbies here in Houston,Tx. Now it just sits on my spare engine shelf waiting until I feel like listing in RCU or Ebay, but that's a
different story, different thread!!!

Mike,
The .60 is a wonderful engine, that got me hooked on MVVS to start with.
Spend it the right fuel first 80/20 FAI, no nitro, preferrably castor oil, though Klotz should do as well, and an enya #3 plug, with 14x8 prop.
@ Larry,
Just run the plug, and check engine response and radio interference. If all is well, I see no reason not to use it. Like big bird said, you can check the resistance to find out what it is.

RE: walbro WT carb question
I made the mistake of trying to remove the disc and shaft ( new never used SPE 40cc) so I could remove the return spring for the throttle, only now to have a nightmare on my hands. Now when I tighten down the brass screw on the disc, the shaft becomes very tight to rotate, and as I loosen the screw, the shaft becomes easy to rotate. Not sure what to do. Anyone else have this problem when reassembling the disc and shaft to the throttle?
