Jarrid,
Got the Weber on and running, but still have a few problems. One of the
bolts stripped the threads in the manifold. Guess I'll have to get a
helicoil kit to fix that??
Engine starts well cold with choke, and hot without, and idles OK, but not
totally smooth. (Is that just because it's not a Honda?) The engine has
always run great, but never idled smoothly. What should the RPM be for the
Weber at idle? It seems inconsistent. Around 900 sometimes, but if I rev
it, it may hang around 1100 for a while. Looks like it returns all the way
to it's resting position. I'm going by the tach in the dash, as that's all
I've got to check it by.
Runs and and accelerates really well, with the exception of brief "choking"
upon initial acceleration from idle. Also happens if I just rev the engine
from idle speed. Too rich?? Too lean???
And one final stupid question. How do I tighten the center bolt on the
manifold??? Socket wrench or regular wrench won't fit in there???
Thanx,
Brian
