I seem to have too much oil flow to the bar on my mac 3200. I have been using 2cycle oil for years to lube the bar and chain. (Iknow, I know, it's not the correct product to use). My question is this. Can the pump be regulated to flow the oil a little slower. Has anyone else been using an oil like myself with decent results. It does seem to work well, but you have to stay on top of the level in the reservior so as not to run the bar dry.
