Re: Still having issues

Well I don't know what to say. I'm still stumped. Didn't change the
cam chain. Put a new head gasket in, reassembled her and she runs
much better at high rpm now. Went on the highway this morning for
about 25 miles. Held nicely between 65-70mph. Did wanna slow down a
bit causing some downshifting coming back but I'm guessing that was
the 15mph head wind.

I don't get how I was getting a decent compression both hot and cold
if that was the issue. Oh well, plugs (which I just sandblasted are
kind of a burnt red now. That's not quite right but could be from
the cleaning.

apart today to check the cam chain.  It looked like it was a 1/2
tooth advanced but once I took it apart and put it back together (had
some seepage from the head gasket I wanted to address) it lined right
up.

After 900 miles or so on my cb175 and countless adjustments it still seems to have a couple of issues I'd think. Will pull just fine through 3rd to 10k rpm,...

Ben Sounds as if you are running dry on your run. Raise the float up a bit try #95 jets, Needles on bottom rung. try 87 or mid octane for a hotter burn The 93...

Ben, check the tach drive if the oil leak is on the right side of the engine. I've had that on several of these. Ernie ... From: kenny...

 No its on the points side.  Didn't think of that but will check to see if the seal back there is leaking.  I didn't replace the ones for the cam so that...

I may be WAY off base here, but your problem sounds more significant than carburetion. My 175's tend to run awesome regardless of where the air screws are or...

If the valves were off I'm assuming I wouldn't have 140ish compression.  No more weird noises than my nighthawk has and rides just fine through most gears. ...

Check the ignition over pretty good. A tired coil or condensor can show up at the higher cylinder pressures encountered at high loads as seen in the higher...

Well I've played with the timing with no results so I guess its time to replace the coil (which tests fine when cold). Any ideas on a cheap replacement. I...
