I have put several post on here about my motor. It is still not right. Just to refresh. I have a 1600 stock cc motor with dual Empi 34 epc's. I have JBug buggy duals on it. I changed to the SVDA distributor. I have tried adjustments on the carbs, tried different timing from 7 to 12, put new plugs in. I ordered new idle jets a 57 and 60 and new 140 main. I put just the 57 in and it ran even worse so I put the 52 back in.
To the best of my knowledge this is how I would explain what it is doing. Oh before I forget.
On the instructions with the SVDA distributor it doesn't list the 34epc as one of the carbs it is compatible with.
Both carbs have a brass tube off the left side on both carbs.
I have a hose off there with a t running to the distributor. I guess they are pulling enough vacuum for the carb to work right.
Now this is what it is doing. When I crank it up and it is warm it idles great. If I pop the throttle in neutral it falls on its face. Not good response. Once I get going it misses and sounds like it spits back though the carbs and pipes almost like a back fire when I am on the throttle. Just at a steady speed it seems better. Especially through the pipes if I really get down on it.
I have checked for manifold leaks and I don't seem to have any. The valves are set good so I don't think it has anything to do with that.
How do I know if the vacuum advance is working like it is supposed to.
I am still trying but it is getting more aggravating. Any comments would be appreciated.
Things i am going to do today include checking the compression and make sure it is good, change plugs wire, and recheck the gap on the plugs.
