choke trouble

ive just swapped the engine in my 2,25 s2a. i also changed the carb of old engine which worked well until engine went bang. now when i put the choke on all it does splutter and pop. can anyone point me in right direction

i had that problem after i attempted to repair my 2 1/4 petrol, i lengthened the choke cable abit so that when fully pulled out it wasn't fully closed.

i eventually sort the problem properly when i figured out what the mixture control screw did! i screwed it all the way in then back out again untill the engine ran sweet, then i managed to put the choke wire back as it was originally.

unfortunatly that engine has since past away

cheers mate i'll try that at the weeekend

Usually / Often ..... the trick with a jet volume screw is to turn it all the way IN, then turn it out exactly TWO full turns.

It seems that the way people design these things means 2 full turns is usually a good starting point. All new engines have to be started from scratch!

So 2 full turns out is usually / often the best start.

keep yer perversions to yerself!

sorry tinny,but i couldnt help it, it had ter be done yer understand

what do you reckon the problem is? its supposed to run fine with the choke off

maybe the choke is choking it

its a pig 2 start but when u catch it u have 2 turn the choke straight off and sit and rev it up till it gets warm

m4ybea tu kneed 4/2 sit the timing & th points an purheeps the mix shag

the engine ive got now had been running on gas would the timing b the same

if it hasn't bin run on petrol fer ages you're gonna have to clean the carb

the carb came off my old engine it ran fine until i killed it

did yer set it or just stick it on?

i cleaned it a set it 2 2 turns and fiddled till it sounded ok. its a weber carb so i hav no proper settings

22 turns, thats a bit excessive

i wonderd what that scew on the floor was
