Re: 1976 7.5 Aircooled Craftsman 217/58588-0
One other thought, if it is fouling plugs or clogging the exhaust at 24:1, drop back to 32:1. This has been the standard ratio on air cooled engines for about 20+ years. Anything older might be 16:1 so 24:1 is a good comprimise, but you won't find any bottles out there that pre-mix to 24:1, so make sure you have a ratio-rite or something similar that can measure the oil for you (6 oz to a gallon I believe for 24:1 - 8 oz/gallon=16:1 and 4 oz/gallon=32:1).<br /><br />I don't personally like poulan products, but the earliest craftsmen model saws and trimmers were indeed poulan, so that is probably sound advice, considering they probably had some kind of contractual obligation with poulan. If you can't find Poulan oil, go with a good quality name brand saw oil (Stihl, Husquvarna, or even Homelite or Lawnboy) avoid the generic brands - there is a difference. Also avoid the "one mix fits all" magic oils. There are a few (very few) good ones out there, but most are 50:1 mix, and some are even 100:1. Most of them are junk, so stick to something decent (tried and proven by the "big boys").
