With a 6.5mm , do you have the new carb or the old carb?

If its the old carb about 3.5-4 turns out from fully closed on low speed and approx 3.25-3.75 on high speed, 1 turn open from fully closed onidle screw will get ya close

If its the new carb about 4.25-4.75 turns out on low and 3.25-3.5 on high with .75-1 turn open from closed on idle screw .

I would recommend 6mm on buggy with that setup and temps from 255-270 and you will see extreme runtimes .

Happy motorin',

Hi.

I'm trying to convince the Danish distributor of O'Donnell cars and fuel to take some 77, 77T and 97T plugs home.

They also sell Axe Rossi engine and plugs, and will only take OD plugs home, if they has the same long shape and short thread as Axe Rossi plugs.




As far as I can see, the threads on Axe plugs are shorter than OD plugs...

Any body knows if O'Donnell plugs fits Axe Rossi engines?

Thanks in advance

Houston - my 367 keeps flaming out and is a pig to tune and I'm pretty sure the front bearing is leaking. Is it possible to fit a standard front bearing instead of the 6.3 type as I have one if these and I don't want to waste £25 on that type just to try it

also what is the part number of the exhaust reducer for the 367 and any suggestions on pipe, clutch and restrictor for it on 30% fuel

I have just started breaking in a n21bf - could you let me know a good pipe combo and clutch setup for one of these please. I have 41021, 41020, 41001,41005 headers and ofna 086, 9901, 9853 pipes in my box

very difficult to diagnose what your flame out issues may be but check all the obvious first . ofna 086 with 41021 header

i couldnt tell ya the exh red number off the top of my head , never needed it on any other engine

What is the OD plug you said to run in my engine?

97t

might try the odonnel 87t also , havent received those yet

truggy after 10 min of runtime , not being gentle on the throttle either

i was racing

So is that the same thing I can expect?

if you get all the elements right , you should .

i had exactly half a tank left in the buggy after a 7min qual also , most others were pittin after 7:30 .

in truggy i was running a houston tuned plus 21-5kt (could of got that runtime with any engine , just what was in my truck )

runtime boils down to properly jetting the engine with restrictor and tune , the proper pipe and having a nicely sealed up crank case .

kyosho st-rr , plus 21-5kt , 2084ss/41021 , 7mm , odo77t , kyo blue alu. w/1.0mm springs , 13/50 gearing , byrons gen2 pro driver , 250°
