Hello all. Hope everyone is healthy and well. Not sure what I’m doing, this is my first ever post on any site and I apologize for breaking rules and such but I’m trying my best to learn and grow here. I’ve got a Husqvarna 141 with a WT 660 walbro carb on it. 50:1 fuel oil mix always. 140 psi compression. Keyway intact and sound. .012 air gap on coil and .024 plug gap. Cleaned entire saw and carb stripped carb including needle valves to make sure passages were clear etc. don’t have a walbro tool but I have the metering lever set to just touching a machinist scale. Pressure tested carb before stripping and was slightly wet internals. Held 7-8 psi for 2 hour. Same after rebuild. Only gunk was at screen. Unit will not start. Only a Pop now and then. Exhaust screen/mesh clean. Only thing I did was drilled the tank hole to 3/16. Insert a 3/16 tube with fuel filter then before to gets to carb from tank I stepped back down to 1/8 stock. There was something pinching the factory hose at the hole more towards tank. Could not get to out which is the reason for oversizing the hole. I’m thinking of everything I’ve done so I don’t leave anything out. It’s long winded for sure I apologize and hope not to be ejected from this site for my ignorance. I can’t do much physically these days because three massive heart attacks, Covid and now diabetes has destroyed my once active life. I went from a working out 4 times a week 44 year mechanic to 50 lbs overweight can’t walk much from 29% heart function to only being able to do bench work. Thank Christ I still have that. But. My bench work in the past was more engines and fab work. I am being bested by a chainsaw that by all indication should fire up. I’ve tried the low needle from 1/2 open to 3 turns open. Results are the same. Zip Anyway. If like I said I’m in the wrong spot for posting or I have broken any site rules I am sorry and if my privileges are revoked I do understand. Thanks guys for your time and patience. I wish you all a blessed Holiday season. Vaya Con Dios.
