I am a bit miffed, got 110 miles out of ?21.00 of fuel (was 87.9 per litre at the time) which i have roughly worked out to be about 20mpg, which i seem a bit low, considering i was changing gear early on and i weren't driving flat out all the time, few full throttle blasts and 5k gear changes. Just seems really low for a 1992 1.4SR thats as good as standard part from an exhuast that won't make a differnce!!! Mind you the chock seems to be a bit sticky and was stuck on for a few 10miles. Any help would be nice!
Autochoke stuck on?
I get much more mpg than that on my engine.

my SR, out of 42litre tank does approx 245miles
so work that out lol, dont know weathers its good or bad, the least ive managed was 180miles to a full tank lmao!
Is the fuel guage a bit inaccurate (as mine is)? Also, when was the carb last set up properly? I was shocked to see that I only get about 28-30 mpg from my 1.2, but then you have to drive it hard to get about at any pace (and I do stop start Chinese delivery)!! Are you doing long journeys at all, or is that all stop start? I reckon I get about 40-45 mpg when sat at 70-75mph.

so its not town stuff then? long range?
no its mainly like daul carrigeways, urban expressways kinda driving, some motorway too
about 4% of it would be sitting in traffic in towns, the rest is constant driving :D had the carb re-jetted and timing sorted, vac advance and choke unit we're replaced lol, its just the how the car was set up
But, bigger engine or break it now so it doesnt really bother me tbh

well, i did have a brand new DTML for a while, i got that setup professionaly at Aldon Auto, an my god, that was so ace! Then my car threw a hissy fit of electrical problems, so i sold it to fund repairs!
Put the pierburg back on and it was ok but hey ho, just sold it on eBay, ?67 complete with Pipercorss filter :thumb:

the pieburg for 67 quid! and what was it better on fuel with DTML or 2E3?

yeah the pierbirg for ?67 :D i sold the DTML, had about 10mile on the clock for ?132! cost me ?254 :tard:
erm, tbh i dont really know, but i would imagine it would be better with the 2E3, at Aldon, with the DTML on, Alan was saying that it will run slighty lean even tho hes set it up, as the DTML has bigger choke mass so will use more fuel
BUT i can safely say i found that theres definetly a noticable improvement in throttle repsonse AND power with a DTML! :thumb:

coolies, i got told it wouldnt really effect fuel comsupmtion that much with DTML but if it needs to run lean then that makes sense!

i suppose its really down to the use of car though with regards to the fuel consumption like
its just ive been arsing about with SR engines nows since about 2004, an ive only just decided to move onto EFi lol wish me luck :D simple engines to ever so slighty more complicated lmao!

I watched that carb on eBay I couldnt believe how much it went to. Hopefully mine will reach that much once i've cleaned it up and bunged it on there!
