Hope someone can help me to get an idea of my problem.
When I accelerate there is a power loose at beginning to about 3 RPM, after that power increasing to normal and all works ok.
What can cause that, maybe someone had same issue out there?
It is clear that it looses power because of too much air - but can not find where it comes from. There should be another reason of such behavior, but I have no idea.
Other idea is that carb air valves opens too much at beginning - but is there any adjustment of that? When I disassembled I not touched valves, and carbs are syncked and vacuum is ok.
Other idea is that fuel leaks somewhere, but in this case why after 3K RPM throttle works good as supposed.
Recently I cleaned my carbs disassembling them, replaced parts with standard kit. All is set back,all works fine, idle speed, starting works like a charm.
I verified carb. fuel level, fuel hoses, pump, new air filter, new fuel filter, engine valve clearance, throttle sensor (on carb), carbs. syncked (vacuum is ok)...
I am out of any ideas, any idea is much appreciated.
