Ofna 8 port engine

[Southwell]

Hi all,

I need instructions if poss on how to put together the flywheel and what washers go where on this engine! I took apart all the bits to fit onto my race engine, and now thats sold i forgot what goes where! Please help

you normally just put the collet on first,then flywheel,then clutchnut.
if the fluwheel rubs on the engine casing then add a thin shim before the collet.
if the clutchnut wont tighten down(you run out of thread),then again add a washer,where you add the washer will alter how far away the clutchbell is from the flywheel or the engine.

Cool, thats exactly what i needed to know, ive only ever build one, and that was ages ago
Cheers Dave!

I got the flywheel on and iam trying to fit the clutch shoes. The problem is they are loose fittinh, will i need new springs? if so can you recomment some shoes and springs please

[dave g]

depends what surface type and wether the track is loose etc..

if you are ona grippy grass track,try some 1.1 springs,if on dirt try a softer spring .9 or 1.0,these will bring the clutch in earlier and kill some of the wheelspin.

clutch shoes are user preference,alloy is supposed to bite harder and be used mainly on high grip tracks,graphite shoes give a little more slip and are better on lower grip/bumpy tracks...im running with the shoes i got with my xtm,they have done about 2 gallon and are still like new(plain graphite plastic) and 1.1 springs..and my buggy was trying to wheelie on sunday,it was far too savage on bottom end.

I was running the alloy ones on the Hong Nor at this weekends neo race and it was hard work. I changed to some plastic ones that jamie booth gave me and it was loads better and easier to drive.

I managed to just change just the springs, 1.0mm, and kept my 1 meet old plastic ones in.
