Just wondering which carb setup is better, also what are they worth to buy second hand? Are parts readily available?

go a single 1.5 or 1.75 with one of graham russell's manifolds, easy to tune, and will probably end up with a better behaving motor.

NO Idea.. what a manifold costs.. ring him... 9630 2195

But Grahem Recomends a single 1.75 for a 1100 I was talking to him just the other day about getting power out of a 1100...

Yeah I like the Delorto & Weber for the fact you set it right.. never touch it agian (untill you change something major on the motor)

40mm will do just as good a job as a 1.75... Plus you get intake noise! Haha

True , but you don't get as even a fuel to air flow ratio as you do with SU's . Depends what you want really , power with economy plus a bit of fiddling , or power with slightly worse economy with no fiddling ....

a single 1.75 or twin 1.25's is what you want for a stinking hot 1100

twin 1.5's are for big block police pursuit engines :D

Thanks everyone

So a pair of 1.25 su's on a mini manifold for $10 would be a good price yeah? Pistons are stuck and needs a kit through them but other than that all looks right!! :roll:

seconded....

1.75 on a standard manifold if you don't want to may the extra for the flash one, still good... you can use a standard 1.5 manifold with a little filing on the intake to open it up

I'm with the 1.5 single SU

Weber or Dellorto for daily is stupid as they put too much fuel down 2nd & 4th cylinder and you end up rebuilding a motor and box way to soon.

Weber and dellorto will give you better accelleration but shorter engine life and if your paying for someone else to do the work its an easy choice.

I'n not quailified to give you advice but neither is anyone else so far?

steve


???? - bit of a brave comment...

That seems to be a bit of a furphy - Webers and Dellortos are viable except for one thing - room under the bonnet.

I have a 40 DHLA and still returning 40mpg and the shortening engine life, only if you dont put air filters on. I am actually getting another 65-70km per tank now with the DHLA...

Easy to tune(lots easier IMHO than SU's)

Horses for courses...!!

Hooroo

My last motor (1310) did nearly 50,000 MILES before I partly seized a piston while thrashing it at Wakefield Pk. It ran a 45 Dellorto all its life.

Bores are still perfect, no signs of this dreaded `bore washing' syndrome proponded by SU lovers...???? :?
I could throw some new pistons in it tomorrow and rebuild it.... 8)

A Weber or Dellorto CAN be jetted properly for road use, but I agree that many are not.

Hmmmm - If it was true that bores #2 and #4 are washed by petrol more than #1 and #3, if this theory was placed against a single HS type carby, would it not be true in saying #2 and #3 would be washed in a similar fashion...

Ponderance...

Hooroo
