Hi,
my parents have a crafstman leaf blower that was purchased in about 1996. It has been used, but not terribly heavily, because it only ran once in a while.
They bought it at one of their houses, which was at sea level. They took it to their place in the mountains (its only 800-1000ft above sea level though) after the first year, and it never ran right. It was never taken back to sea level to see how it ran, but it was taken to sears for warranty repair, which kept it from running right still.
The probem was that typically it took 50+ pulls to get started. The engine doesnt have a primer bulb, and Im sure that doesnt help, but we have a LOT of other 2-stroke equioment, and this doesnt seem to be an issue with those other pieces that dont have primers.
Well, I went away to college, and they could get it running sometimes, so I guess they never bothered with it much. however, Im at home for the holidays, and we were using it for moving some leaves today.
We pulled it and it started suprisingly well. It took a few pulls, but it had been run dry and had been sitting a while. OK, great...
But the problem was, it wouldnt run if shoke was less than 1/2. It seemed to run best at somewhere between 1/2 and 2/3 choke, but at full throttle, it still wasnt very happy, and this was obvious - it didnt make anywhere near the power that my echo 210 blower/sucker does. Now sure, my echo is a lot newer, and it is an echo, but this thing has never run right.
So, given the situation that it takes a few too many pulls to start, it will only run if choke is 1/2 or higher, and it is lacking power, how should I start to attach carb adjustments? Everything else 'tune-wise' is in perfect order, so Id like to try to adjust the carb.
Any suggestions how to best start and execute?
Thanks!
