I just found out my wifes coworker, The Dr Vet's husband, has a 75 2.0 with a dual Weber downdraft conversion. I stopped by last weekend to take a look. it has some minor electrical issues which I should be able to sort out fairly quick with proper diagnostics. Horn, lights etc..
One of his main concerns is mis firing and sputtering during acceleration. It is a fairly clean set up bought from a guy in Bremerton back in 2000. I forgot his name but should be active on this site.
so under slight acceleration, reving the engine it sputters around 2500 RPM. with no gauges or tools I noticed the F/A screws on the driverside carb were out different ratios. I gave them a slight adjustment and it seemed to help. I figure we need a air flow meter to put over each venturi and dial in each barrel evenly.
Being a V-8 guy I would slap on a vaccume gauge and adj from there.... I did not see any vacume ports so its all new to me
How do you boys dial these babys in?
I was also under the impression a stock FI cam is not really compatible running carbs...
Shoot me some ideas , once I get him running, I will have a new teener buddy in the neighborhood to tool around with since you Teener Tuesday boys are afraid of coming accross on the ferry
