Re: TACHOMETER and SMOKE
1 I would suspect a defective tach, or the wiring therto, because if it were the pickup, the engine would run rough or not at all.<br /><br />2,All 2-cycle outboards will smoke. Some oils produce smoke more than others, and as fuel ages in the tank, it becomes stale,and the ratio of oil to gas goes up.<br />Penzoil,Valvoline and Lubrimatic natural oils seam to smoke more than the others to my experiance. Quicksilver and WallMart's Supertech2000 naturals seam to smoke the least (again, from what I have seen).<br />Have you decarbed the engine lately? That carbon can glom-up return systems and internals (ring lands, exaust ports and such) in less then 60 hours...Less on the "smokey oils".<br />Anyhoo, if you haven't and plan on doing it, be forwarned, it will smoke like a mosquito fogger at the drive-in while you are decarbing, and for an half-hour afterwards.<br />But the increase in compression and performance can be shocking sometimes.<br />And another side effect, it will smoke less, as it has less carbon,which adds alotta smoke as it tries to burn.<br />Just my opinion.
