Husky 246

[fleafart]

Picked up a 246 at a flea market the other day. Real nice machine. Cleaned it up and and it still won't start. I think there is still remnants of the bad gas in it and it has good spark but I wonder if there is a way the timing might be off outside a slipped flywheel. Thx.

Are you getting fuel in the cylinder? If it had been sitting up for a long time, I'd suspect varnish buildup/blockage in the carb. I'd check the jets and diaphram first.

Try a little gas down the sparkplug hole. Not to much, you'll flood it. If the saw fires like it wants to run strong, chances are the timing and ignition are good. This tells you a fuel problem is there. Rich.

Thx for the advice. The old gas mix was drained from the tank and pickup/filter line and I removed and checked/cleaned the top section of the carb. No dirt or sticky buildup evident. No restrictions of exhaust, I have to guess there was just more reserve of the old stuff in the bottom section of carb. Plug gets wet and I verified consistent spark through the plug. Good compression. This thing is a joy compared to the usual yard sale Macs which I get running. Maybe part of the problem was first fed it 32:1 until I read more threads and now have 40ish:1 .

Flea...welcome...interesting name...lol...try replacing the plug...even though it sparks out of the cylinder..it may not under compression...had new plugs do it to me...and yes, open and clean both sides of the carb...replacing the parts is available near you...dont forget the welsh plugs!! Varnish can build anywhere and everywhere...the difference of 32:1 and 40:1 will not make the saw not want to run...like Rich said...dump a little fuel down the spark plug hole..and pull on it...it should fire...or you have bad spark....providing you didnt dump too much fuel of course...(been there done that) Good luck!!

fleafart, that is a very good question, but I think some simple things may have been overlooked. If you pull the saw over a few times, and get no fire, pull the plug. If the plug comes out dry, not soaked with fuel, it is either not enough fuel or too much air. Make sure the choke is on and functioning. If the choke works properly, and the plug is still dry, not enough fuel. Check those things out. No use going into the carb needlessly.

On a 2 cycle engine a carb overhaul should be conscidered preventative maintenance. Not a bad idea to go into the carb (or have someone do it for you) on any used saw you get. I have two saws that I got with scored pistons, root cause of failure on both saws was carb related, one was plugged with very fine sawdust the other had granite diaphragms.

 

[fleafart]

You guys are the best. secondly it stihl won't start. I guess it won't be happy until I get the whole carb apart. I still think it has something to do with timing because I never got a pop.

Not that it matters but the reason I got the name was that I was somewhat intimidated while logging on. I'm an ole fart and go to a lot of flea markets. I went brain dead while picking a name for posting.
