Race fuel will solve your storage problems. Expensive, but better that rebuilding carbs and changing hoses.Don--I have become extremely frustrated with what happens to our cars in storage , often after less than a year now, probably due to ethanol as a compounding problem .You go to drive your car , it will not run right or idle etc due to residual junk “in carb passages” after evaporation of fuel , plus what is in tank goes bad .Don’t even say Stabil , it’s ethanol .Briggs and Stratton make some special stuff, as they have fat in this fire. I have been using it . It is an engineered product can’t hurt is thinking but still the issue remains . With a lot of cars able to go this gets really bad .I wonder if anyone in club has a real answer ? “ Stabil worked for me “ is not a real answer , as in moonlight worked for me .Someone mentioned putting two stroke oil in with gas ,— that might work especially if a strong mixture of this was drawn into carb the day you put it away and you are rigorous about it , keep records etcI was thinking modify fuel line to a well done rubber hose or special fittings so you could easily disconnect and do this, put the filter right at carb , disconnect line hold temp bottle with a hose at bottom , up over for last few minutes ?“Original looks “ that do not work is just not so good .But the big takeaway on this I found yesterday on a hot rod site , as I have a 318 78 dodge truck recently restored , idle mix screws sort of unresponsive, stalling etc etcWent looking about erratic inoperable idle screws on Carter( saw that issue many times on 300 )— it has a rebuilt carb Carter BBD 2 bl rebuilt only a few years ago and ran great before two years on non use . BBD variations were used from 50 ‘s to 80’s as the mopar 2 bblSo on the site the guy mentioned that the problem arises in the narrowed- down tip of the very narrow brass tubes that dip into fuel to feed the idle circuit . The hole at the end is long and tubular , smaller than the smallest drill in a 100 drill numbered set . It is made I think by swaging brass tube down . I believe AFB are same design , these tubes and a cover on them are part of the main venturi cluster held in with two special screws . unfortunately you have to pull carb top to get at it. Best done with carb off …. obviouslyAlong the lines of why not try , i did this , sure enough junk in tiny tip hole fromdried gas . cleaned out with stainless wire , blew out with air … It works! Idle screws out 1.75 turns like normal !’ Before 6-7 turns still not running rightAwwwright!All these years thinking some mysterious thing happens to carbs , cured by rebuild , $ time and hassle . Now I feel I know something newGood toknow …Still learning … may help you , —- that , and use current edelbrockneedles inour carbs , that cures deformed seats inside carb from too much golden screwdriver as taper is differentjkg--For archives go to http://www.forwardlook.net/300-archive/search.htm#querylang---You received this message because you are subscribed to the Google Groups "Chrysler 300 Club International" group.To unsubscribe from this group and stop receiving emails from it, send an email to chrysler-300-club-international+unsubscribe@xxxxxxxxxxxxxxxx.To view this discussion on the web visit https://groups.google.com/d/msgid/chrysler-300-club-international/5EABC89C-C52B-4A78-9FB5-6A560DCACEEF%40gradyresearch.com.
