Mathew,I'll need measurements across the cup & depth.It's OK if you do it in metric,but inches is preferred.
Brufab,sounds like your saw could benefit from a 1/4 turn out on the lo needle.
I got the Monkey Wards 4.0 running! I took the points out for a cleaning,they were filthy black,but no pitting.I took the top off the Tilly carb & a good thing I did.The pump diaphragm was stuck to everything.Lots of oil in /on the diaphragm which probably saved it.The choke rod was in 2 pieces,I just stuck it back together for starting purposes.I'll have to see about JB Welding it back together.I usually give a saw 15 pulls,then anything after that I'll give it a prime.The saw sputtered on pull #13,Lol.Runs,idles,& throttles up beautifully.
