Warning im ADD OCD and have nervious issues this will be long winded.
I will assume there are at least a few cats here tech savvy on the pict 34 3 and vw engines,
Ive been a gear head close to 40 years wrenching on all kinds of junk including other trikes and vw vehicles but this time im not finding the solution,
One problem is it doesnt always do it,
Basics 1600 dual port pict 34 3 vac dizzy,
To the best of my testing no vac leaks and valves are set.
The carb is adjusted as per rob and daves online papers which with the exception of fast idle adjustments most agree on turning the pict 34 3.
Its not epic.
But here is my issue, take off run thru the gears, it doesnt like 4th before 40mph then up to 45 to 50 now get off it, downshift to 3th and about 8 out of 10 times it bucks and stumbles wants to die takes careful finesse of throttle to keep it going then smooths out runs great, within a minute,
Did it go lean or rich?
Another symptom, running about 35 to 40 in 3rd floor it, sometimes it takes off smooth and hard, well as hard as a 1600 takes off other times it has a stumbling flat spot that then after it clears it doesnt do it again during that outing
Has anyone has had these type issues.
Now related unrelated,
Pict 34 3 adjustments,
For the accelerator squirter, how do we know if it needs more or less?
Since a trike is lighter could it might be happier with less squirt?
Any great way to know the squirter is set correctly?
I have seen at least 4 different ways to set the so called fast idle screw on the choke stepped cam,
Most want a little more that the screw just touching the cam .25 turn past just touching,
That really drives my OCD nuts anyone got a more exacting way of setting it?
Just how critical or forgiving is it?
Many thanks
cheers
