i'd say that was way too big.
tried a 24 chopper on my mates ring 21 with a 275 cossie and only just reved to 5600. try 1 if you are brave enough but and its a very calm day but i'd suggest something like a 23 laser. my mate is running a high five and its just as good

Don't know a lot about ring 21's but it should rev more than that - either it was very low or that engine was a bit less than 275 IMHO of course ...........

cossie
I know nothing about these engines, but from what I have heard and read they shouldn't be reved over 5 1/2K.
I do know parts are as rare as rocking horse shit though!

Yes so true i dont want my engine reving to 5500rpm cos she will blow, Burty either youre mate didnt have a 275 or he was very lucky.
I want a nice big prop to use some of that torque i have.
Roofer might be intreasted in your prop pm me a price etc
Cheers

engine is mounted on setback plate and is quite high.
think there is something wrong with the carbs because it splutters and bogs down on pull away
