JustGav Posted May 27, 2007 Share Posted May 27, 2007 Okay, My dad and I have pretty much finished his build of his mg midget. The problem he is having is balancing of the dual carbs on the 1275 A-series. Does anybody know of anybody within the northampton area who is capable of doing this properly. Last time my dad took the initiative and took his car to a garage without asking me, they charged him £300 to swop the intake manifold and a bolt. After having rebuilt the engine from scratch, I'd rather someone with carb experience do the final tweak. Thanks Quote Link to comment Share on other sites More sharing options...
edge Posted May 27, 2007 Share Posted May 27, 2007 Is he a member of any MG forums? Sure that could be a good place to start. Quote Link to comment Share on other sites More sharing options...
JustGav Posted May 27, 2007 Author Share Posted May 27, 2007 Is he a member of any MG forums? Sure that could be a good place to start. He is a member of an mg board, but from what I've seen they certainly don't have the same spirit at has been shown here. People on there are more than happy to shift bits, but my dad isn't clued up enough to ask on the forum and stuff like that. My dad isn't a technophobe, but a little bit of tech (ie computer) and it gets dangerous *grin*... He has just gotten to grips with sending me pictures via email... (Was yelling at him over the phone in Tescos the other day, because he wouldn't listen to me when I was explaining how to resize photo's to email them to me)... Spent ages rebuilding the engine, rebuilt gearbox. Just getting the last bit done... I've done the timing for my dad and it is spot on, just the carbs to do, but I've had 0 experience with carbs apart from tweaking the odd single one, balancing duals is a bit trickier I assume. Attached, my dad the old-boy racer *grin* Quote Link to comment Share on other sites More sharing options...
edge Posted May 27, 2007 Share Posted May 27, 2007 There is a tool for this and its a simple theory from what i can remember. Something like long tubular vac tubes. I will have a lookski Quote Link to comment Share on other sites More sharing options...

I will have a lookski Hmmm, I bought him a carb balancer off ebay and dropped it off one day with a note saying 'If it had FI I would do it, but carbs, here you go...' Might look for a how to for him... but I think he is at the stage where it is the last thing to do and he would rather just get it done now, I live 2 hours away so can't just constantly drive up to him to tweak it...

AndyT Posted May 27, 2007 Share Posted May 27, 2007 Sympathise with you mate, balancing those carbs is an art form in itself. And a dying art at that. Not sure you can even get the required vacuum gauges either. I'll have a looksee. Quote Link to comment Share on other sites More sharing options...

Mike M Posted June 1, 2007 Share Posted June 1, 2007 You can do it by ear with a stethascope Yep, it's the only way I've ever set up my twin webers along with a colour tune kit. You can fine tune with a manometer but not sure where to buy one. I'm not looking forward to setting up the dual choke twins on the new vdub engine when I finally round to it.

Steve Posted June 6, 2007 Share Posted June 6, 2007 I have used Northampton Motorsport in the past when i had my Lotus Esprit. They stripped, cleaned and rebuilt the carburetor. The car was perfect after that. They were very reasonable with there costs to. Quote Link to comment Share on other sites More sharing options...

dangerous brain Posted June 6, 2007 Share Posted June 6, 2007 Oh the big downfall of the twin SU. Problem with them is they need constant fettling to keep them running good. Hows about a bigger single carb? Quote Link to comment Share on other sites More sharing options...
