Carbuerator Overhaul on a Huskavarna 154 Se
Hi Restrob, Originally yes I did replace those gaskets but not since.
Plug still looks new. What about that third screw on the bottm under the high low mixture screws ? It is for idle but seems to directly affect the mixtures because after the overhaul she was racing and I lowered it and the mixtures went out of wack and needed a reset. What part does this play is it like the old Carter AFB carb where you had the big air bleed on the bottom between the mixtures ? Does that screw control a air bleed ? My car spark tester does not seem to work on this machine must be different in voltage than a car engines voltage. I was so furious day before last that I wanted to send it sailing into the nearest wall. restrorob wrote: Auto Tech Wrote: Hi Restrob, By now you must think ""Oh what does he want now"" When you see me write you. I managed to get the pull start to work and got her started. Now I checked the crank for play while the recoil was off and no play. However I am going to fling this saw off a wall soon. I replaced that screen you told me about while the saw was apart for the pull starter and she started up running great however a few moments later she started to hesitate on high r,p,m engagement so I tinkered once again with the fuel settings and she is more responsive to fuel mixture tinkering and stalls much quicker BUT she is having so much trouble when I pull up on the trigger for high r,p,m's she dogs and I adjust and move mixture only say an 1/8 of a turn either way and one way she stalls almost instantly and the other she loads and stalls. Her idle mixtures are even more sensitive and she was never so sensitive. Any idea's any thoughts is appreciated. OK, Have you replaced the spark plug since you have been adjusting the carb. so much ? Is it still white looking ? Do you have a in-line spark tester ? Did you replace the carb. mount gasket ? Did you get the gasket on right where the small hole aligned with the impulse hole in the cylinder ? Close both the low speed and hi speed adjustment screws. Open the low speed one turn and leave it, Open the high speed 1 1/4 to 1 1/2 turns then start it up and try adjusting the high speed only at this point. Opening is richening closing is leaning, If you get the high speed adjusted properly go back to the low speed and fine tune it. A lean low speed (Screwed in too far) with cause a bog on throttle up. +-------------------------------------------------------------------+ +-------------------------------------------------------------------+ -- restrorob |

The idle adjustment screw only regulates the butterfly, Set the hi and low screws where I suggested and try starting it. If it idles too high with the low speed adjuster opened at one turn leave that adjuster alone and only lower the idle screw. If you still can't get it running properly have a friend snap a picture as it hits the wall and post it here. Then go buy yourself a STIHL and be done with it !!!

Carbuerator Overhaul on a Huskavarna 154 Se
Ha ha ha ha ha ha ha ! I will do that and the way I feel right now I am
in need of a saw that is better. I do have to give credit where credit is due and that the Husqvarna served me for years with out one glitch. I got this saw by doing work for someone on his vehicle and he could not pay for the work that was done so he gave me the saw as payment and that was some 10 years ago. restrorob wrote: Auto Tech Wrote: Hi Restrob, Originally yes I did replace those gaskets but not since.

Sell it on eBay and get a STIHL
JD "Auto Tech" wrote in message oups.com... I had developed a severe stall condition especially when you tried to use high rpm jets. I bought a carb kit and overhauled the carb BUT lacked the information on settings internally BUT the carb did not look very complicated. I am a A class Ford Technition and have loads of experience on lawn tractors with B&S and Tucemseh but really have no experience with 2 cycle engines and carbs. I am also having trouble with chain stretch and my chain is only a few months old. BUT top item is low on power and dogging while cutting thick wood and Misquite. She alsways seems to need variances on fuel mixture as she is used and it should not need this one setting should do it. I live in Nm and cut wood daily with the saw for heat purposes. This saw is a critical tool for everyday while winter lasts. Any help is appreciated.. |
