Good. Don't know how long you ran it when it was bogging but could have been bad gas in the greater fuel "system" - lines, filters, etc. When you winterize remember to put stabil or seafoam or whatever in gas and run it long enough to get the stabil etc. through the entire system. Also condensation builds in the tank and system over the winter. Some guys get the fuel as low as possible for winter. Other guys store for the winter with the tank full to the tippy top in an attempt to avoid condensation. I put in the stabil etc. and run it for a good while then fill it to the tippy top but I find that this argument is like the oil or hand signal discussion. To each his own. But sounds like it might be corrected.
