does anyone have a stock carb setting for the ops speedster please?

engine seems to be running ok but im not getting great mileage in the xray buggy,about 7 1/2 mins,that sound ok?

im on the ops pipe and running 8mm spacers in it,which would give me the best mileage,short or long pipe?

hey i used to run that engine and when I started i was told 3 out on the bottom and a little higher than flush on the top in a rich setting for breakin.

fastboy

ok thanks

ive ran it in,shes done 2 gallons now and still got mechanical pinch at tdc.

ive got 2 of them,the torque and the high rpm version,they both run good but as i said,not sure if the fuel economy is good enough.

my needle settings for both are pretty similair,the main needle is only half a turn from being closed fully tho,the lsn is 2 turns from being closed.

Dave,
Turn the bottom IN 2.5 turns from flush, top should be about 2 turns out from closed. if the top is still too rich you may have a bad top end needle seat, you can get a new one from Amain, just look under the Radical parts.

ok thanks ill give it a go.

heres what my carb looks like,my idle screw is on the other side(piston side) to the others ive seen which are on the clutch side..did they change the design?
