Are you disconnecting the vacuum line when setting timing?
The harmonic balancer is you crankshaft pulley, it has you timing marks on it. it has rubber on inbetween the pulleys. when they get older the can spin inside. so when you set your timing, the marks are off and it may acually be retarded on timing. you cant adjust the balancer but if you advance the timing and you dont get "PINGING". then this can help determine your problem. Hope this helps.Tim
Tim, i double checked all marks and got it set pretty close, however, now the starter makes a very ugly noise when attempting to start. Would the timing adjustment have anything to do with that since it never did that before?? How do i eliminate the omg noise?
does it sound like it is dragging real slow? If it is then tour timing is too advanced, back it off some.
Tim, i tried that and now it stumbles pretty bad when idling, any ideas??
I set it back to the original of 20 degrees btdc and it stumblems about every 3 revolutions of motor. Any ideas ??
Tim its a new dist. installed 4mths ago. The gears look brand new...all of them.Could it be possible that rich or lean on the carb might be needing adjustment. If so, do you info for that too?
yrs i do butn the mikuni carb is the hardest to set up, we charge 3 hrs for this, its a hard job, i think its still in the timing or the exhaust, are you sure the exhaust is free,?
Iknow you said the carb was rebuilt, but there is no complete kit to do this, just partials, I replace them with a carter 2 brrel and everything is fine, I've never found, in 20 yrs anyone thatcan rebuild them. Just my experiance.
yes Tim, the exhaust is free flowing, supposedly the guy who re-built the carb is a well respected tech. and has been doing this for many many years, he was referred by almost all the parts stores around when i inquired about the carb. Is carter a brand name and are they on the web ??? is it a take off and put on fix or is there many tricks to apply?? I will double check the dist. rotor button and make sure it is lined up properly again. Have you ever experienced it to slip once set ???
Is there anything to consider to take out the stumble from existing carb? Do you have access to vacuum line diagrahm to narrow down the search? I have already verified that there are no vac. leaks, yet the stumble remains. any ideas ??
thanks for your help
