Dave, The standard carbs are 1.25. Not as good as it could be but significantly better than the Stromberg 1.5. Rob C Webfoot Leisure.com rob@... 866-530-9801 toll free robbiesg@... 31929... MORE
Sounds like either a) more suction on the front carb - in which case you need to balance the carbs, adjusting the throttle stop screws of each whilst litening to the induction hiss from each one in turn - or using one of the many crb ballancer kits available or b) You have not got the jets adjusted to the same point on both carbs, allowing the front one to pull more fuel through. The start point is both jets flush with the bridge ( see "cryptic manual" thread ), and then lower both jets by the same amount... MORE
Hi, I=92ve just =91joined the club=92 with my 1960 leaf-green frog. I bought he r back in February and although completely restored, she=92s been sitting in a gar age for 7 years, so I=92ve been quite busy making adjustments and sorting a few teething problems. Although she=92s running fine for the moment, one of the Carbs needs reconditioning and I need an electrician to check over the loop. Can anyone recommend anyone? (Preferably in the Southern England region) - and if ther e =92s somebody who can do both =96 albeit unlikely =96 that=92d be grand! Oh, and Radio!... MORE
Hi list, I have huffaker spec 1 1/4" HS2's on my 948 competion motor. When I look in the air rams I see a fountain of un-atomized fuel coming up around the needle of the front carb while running. No fuel is visible when looking in the rear carb. I'm guessing the front float bowl needle is not shutting off and pressure is building up and forcing the fuel in the carb. I have a holley pressure regulater that I think I have adjusted to the minimum pressure (about 1 psi) Is this likely the cause? (I have new... MORE
Are the standard carbs from the 1300 Spit setup 1" or 1"? David "David Jacobs" 31915... MORE
To add to the fund of general wisdom, I got my dual carb setup for my 75 Midget from a 1300 Spitfire. The manifold and carbs fit the 1500 perfectly. Rob C Webfoot Leisure.com rob@... 866-530-9801 toll free robbiesg@... 31914... MORE
Nigel, I agree about SUs - excellent carbs. But the twin SU set up for the 1500 is not that easy to come by in the States, so a change from Stromberg to Weber does make sense. Guy "Guy Weller" 31911... MORE
My reasoning for going with a DCOE is for the following: 1. It was originally fed by a Zenith Stromberg carb for the 1500 midgets. I'm doing a complete restoration on the car, however, between the engine that came with the car (with a thrown rod) and the one I purchased to rebuild, neither came with a carburetor or a distributor. 2. I want to get rid of the zenith stromberg =) The engine is a basic 1500 engine. Stock cam in it, 9:1 compression and .020" overbore from the rebuild. Currently no head porting or anything done to...

Cap'n Yes Brit 1500's come with twin 1 1/2's which works quite well on the 1500. If it's a stock 1500, its a waste of time putting on DCOE there will be no performance increase and itll be trickier to set up. But his choice.... Nigel "amukdigiphoto" 31908... MORE
Guy Aha! That may explain it then, but I noticed how the original poster of this query totally ignored my comment ! LOL Even if it does have a Stromberg - I still feel it would be better to slap on some twin SU's than go to the bother of a DCOE. Good carbs they are, no doubt about it, but I fail to see any benefit at all of fitting one to a bog standard 1500, specially when you consider how tricky they are to set up. People are quick to dismiss the twin SU setup, but they're... MORE
Nigel, I agree if Chris is starting out from twin SUs but if it is N American spec it will be on a Stromberg and a DCOE will certainly be better than that! Guy "Guy Weller" 31897... MORE
Guy Weller writes "...but a DCOE will certainly be better than that!" (single Stromberg) Absolutomundorino. That Stromberg with it's autochoke strikes me as a GIANT PITA. Of course, teamed with a catalytic converter mounted in the engine compartment, nothing within stands much of a chance in any event! :):) What a lousy "system". Cap'n.

Is that the SU pump number? Nelson "Nelson Wittstock" 31886... MORE
I'm running a pair of inch and a half SU's and no idea what the fuel pressure should be. Nelson "Nelson Wittstock" 31884... MORE
Dear Listers, All this fuel pump talk has got me indecisive. Had to have the car towed home after the mechanical pump crapped out with under 1500 miles on it. I now have the motor out for clutch replacement and vacillating between buying a new mechanical or getting a $40 Warburg electronic and fitting that. Besides the usual concerns I'm also installing twin SU's to replace the ace Stromberg. The larget twin fuel bowls are a concern or am I being iggerant? Advice and comments are kindly solicited Rob C 75 Midget being redone right..... I hope. Webfoot Leisure.com... MORE
Chris Me being me, and being unlike anyone else on here, I'm not going to give you the information you want, but simply ask you why you're thinking of putting on a DCOE in the first place? Is your 1500 a real firebreather needing a lot more air than a standard engine? If it isn't, to be honest, I can't see the point of installing a DCOE on a standard 1500, you won't see hardly any benefit at all until you reach the very highest BHP the engine is putting out. And how often do you actually drive the... MORE
I hadn't noticed the high Buy it Now price but that does make it less attractive. From what I understand now, the SU electronic pump is the best way to go. Buying it from LBC I will get the discount on the Moss price bringing it down to $107.06. Also looked at the possibility of rebuilding the mechanical pump and can't figure out why the rebuild kit costs more than a new pump. Guess they don't want to sell the kits. Thanks guys, Nelson 62 Sprite still needing many $ "Nelson Wittstock" 31870... MORE
Bob... Larger bowls are of no concern. Pump doesn't care unless the engine is highly tuned and than one can use a higher pressure (output) with a pressure reg. I find the low pressure (LP) Facet (4psi+-) mounted in the rear in place of the SU... works fine without a pressure regulator on SU's. With my PO'd "Vizardized" 1340 (90HP at the rear wheels) I used the HP Facet (6-8psi) with a pressure reg. set to 2.5psi for a 45DCOE. This engine went to 7k and was mostly used between 3500-4000rpm on the highway. It was also capable of... MORE
Hey Chris (and Nigel!:).... Don't Brit 1500's come with the twin 1.5 SU set-up? If so Chris, why would you want to convert to a 45DCOE on a (assuming, here) stock 1500 motor? Are the SU's clapped out an in need of overhaul? Cap'n. Bob '60 :{) PilotRob@... 31877... MORE
Typically the low pressure pump is used with the SU's. It's range is 1.5 to 4 psi. Pump number is PRO #42S. Has blue decal on the pump. Usually no pressure regulator is needed. Best, Paul A "Paul Asgeirsson" 31885... MORE
I used one for a while instead of a standard SU electric pump on my 1275. It worked fine and I can't remember why I changed back, but it was probably something to do with not being able to dismantle the electronic one if ever anything was to go wrong. Incidentally, the Mechspec 'Buy It Now' price of U$70 + 18 shipping seems a bit steep to me - even Mo$$ list a pump for the equivalent of $80. David "David Jacobs" 31863... MORE

It can be done, you just have to drill and tap the manifold. But the usual reason for putting on a DCOE is for performanc, not economy. The vacuum advance is an economy device used at low throttle positions, hence high vacuum conditions. Paul A "Paul Asgeirsson" 31869... MORE
