I have a 2.0 type IV engine with 44idfs on it. I was going to sync the carbs today and noticed that even when not pumping the throttle the accelerator pump drips a stream of gas down into the throat of the carb enough that its pooling up a bit on the throttle plate. I'm getting popping back through the carbs. Timing is spot on and the valves are correctly adjusted. I take it this is a problem and they arent supposted to do this? It also smells like its still running to rich. I have 135 mains, 200 airs, 55 idles, 36mm vents, and no velocity stacks currently. Mixture screws are set 1.5 turns out. Its also hesitating from idle to around 3K rpm if I step on it hard like its flooding out. Time to put kits in the carbs? Does the jetting for the accelerator pump need to be changed or adjusted?

I realize that this is a bit of apples and oranges, but.....my 2.7L has a smaller hole (450 cc) than the 2.0L. I run 60 idles, 135 mains,145 air corr., and 34mm venturi. Is this rich?....or whut?
I also like NGK plugs. For a low compression motor, something on the order of BP5ES. Welcome to MSD "burn thru". I didn't go to that stuff cause it's pretty. Guys say the MSD ain't worth spit cause you don't get any hp from it.....true, no hp, but it makes them run smooth down low....when your a *tad* rich. I got tired of fouling plugs. The point is: carbs is carbs....tho the engine characteristics are a tad different. I know diddly bout T-4s, but you seem lean on the mains. Odd to get fuel reversion from a motor/cam with minimal overlap....or so it seems to me. |
