That4doorKiD Posted September 14, 2015 Report Share Posted September 14, 2015 L-16 210 head 32/36 DGV Weber I'm not a good reader when it comes to research I'm sorry for asking such a brought up topic. But would 900 rpm's be good for my idle. That's what I set it to by twisting the distributor and adjusting the idle screw. BTW my carb. backfires/spits out the intake when I rev up the throttle, Vacum lines are plugged What's the best degree's and rpm someone has run this at? http://vid1293.photobucket.com/albums/b600/h7030/VID_26451208_073644_zpsqmvgom06.mp4 Quote Link to comment

Also when I rev it up even all the way, it doesn't backfire. :devil: Quote Link to comment

DanielC Posted September 15, 2015 Report Share Posted September 15, 2015 In my experiance, 900 RPM idle is a little high. This may be fast enough that mechanical or centrifugal advance is starting to come in, making it difficult to set the timeing accurately. Timing specfications are usually at a RPM below the mechanical advance coming in. There are also some ports, or slots in the carburetor, just above the throttle plate, that at a slower idle are above the plate. These slots help with the off idle transistion. If the idle is too high, the idle mixture gets set with the off idle ports already being used, and that affects the idle mixture. Too high of an idle speed can also uncover the vacuum advance port to the distributor, and this also can make settingthe timing difficult. 2 Quote Link to comment

Fine tuning you say.. sounds like what I'll run in to when I start it on the road. I'd benefit into researching this moar Quote Link to comment
That4doorKiD Posted September 16, 2015 Author Report Share Posted September 16, 2015 good job 10-14deg might run better depending on gas quality Yeah, I'm going bump it above 5 to 5-10 degress advanced, and I want to keep it under 1000rpm. probably gonna run medium grade fuel, possibly premium for curiosity Quote Link to comment
datzenmike Posted September 16, 2015 Report Share Posted September 16, 2015 8.5 compression will run ok on regular gas. Quote Link to comment
