Built a 2.0 from a 1.8. Planning on putting it in my 72 VW Bus. The IDFs finally arrived from Covid ravaged Spain... 5 mth back order, jeez
Anyway, seems to be running great. Starts right up, idles nicely. I do get some black smoke at idle and just as i let off of the accelerator from 3000rpm. But if I slowly release from the high revs, I get no smoke. Engine on a stand.... Pertronix 3 module, just over 3 fuel PSI Idle RPM is 800 snail reading on all four is just over 10 IDFs are new from Aircooled.net. I got the bench set up from them, so they should have taken them apart, cleaned them up added 28mm venturis idle jets are 50 Main jets are 115 What do you think about getting rid of the smoke? https://www.youtube.com/watch?v=YvuyDxEeyxI https://youtu.be/YvuyDxEeyxI |
