I ended up stealing the switch off my 610 build from last summer (had problems with it & wouldn't run right).I got it al;l together & noticed the needle grommet is missing,but it fired right up & ran beautifully on about the 4th or 5th pull.That 610 has great compression.
So when I had the 610 build from last summer apart to sdteal the switch out of it,I noticed the FW was loose.Me being a dumb ass & always in a hurry forgot to tighten down the FW nut.I took care of that & put the recoil back on & hoped that it'd start & run fine as I'd replaced the FW side crank seal (the other PTO seal was replaced before I started putting it together).It does run,but it idles hi & lo & I had to turn the needles out more than usual.It's got an air leak somewhere that I can't figure out.I guess I'll have to tear it down & start from scratch & try to get it right.
