Bear with me if this is a long post. I have a very clean Jonsered 361 (Frontier, Husky, Skil,etc) that has been in the family since I was a kid. It has been hard to start as long as I can remember.
After sitting on the shelf for 20+ years I decided to get it running again. The piston and cylinder look great. 155 lb compression on my tester. I replaced both crank seals, rebuilt the carb with an OE Tillotson kit, replaced the fuel filter and line, cleaned and set the points to .015.
After all that, the saw is still very hard to start. 20+ pulls before it fires on choke. Once it fires, it runs perfectly. Idles smoothly, good throttle response, plenty of power (for a 35cc saw). It will hold pressure and vacuum overnight. What am I missing?
