MotoJ Posted May 14, 2020 Report Share Posted May 14, 2020 Are the floats plastic or brass? The benzene in today's ######ty gas can impregnate the plastic floats and they swell up or even allow fuel inside. Maybe switch for new floats and needle, too, just to be thorough.

racepres Posted May 21, 2020 Author Report Share Posted May 21, 2020 Update...Yes, Plastic floats.. No, Not damaged that I can Pinpoint. Somehow all that was needed was to adjust Float Height on left Carb... The Viton Needle Tip does Not seem damaged... all Good in my Hood ATT... It just might be that I have been over-aggressive with the Tickler... IDK ... I normally only use the tickler on the left carb, as it is Easiest to access...Time may tell..

Scott E Posted June 10, 2020 Report Share Posted June 10, 2020 I only buy non-ethanol gasoline for all my vehicles. Back when ethanol was first mandated they did not let any service stations sell non-ethanol gasoline. After so many people started complaining about ethanol destroying their small engine equipment the EPA relented and allowed non-ethanol sales at service stations. I get better fuel mileage running the non-ethanol fuel so the added cost for that fuel is not really more expensive than that cheaper fuel and it's resulting lower fuel mileage and the damage done to the engine from something it was not designed to burn. I fabricated some equipment to remove ethanol from gasoline for some lawn service people back then after they saw the rig I built for myself for doing that. Running ethanol gasoline in their lawn mowers and other equipment was costing them a fortune and voiding their warranties. Quote Link to comment Share on other sites More sharing options...

Scott E Posted June 18, 2020 Report Share Posted June 18, 2020 Found a fix for the occasional float needles leaking on my stock Pekar K65 Carburetors. The Wallbaro needles helped but they still leaked every now and then. After looking at the base of the port where the needles stop fuel flowing I noticed it's just a flat surface and a hole with a sharp edge where the needle tip sits when the bowl is full. I made a tool to fix that. It's just a 1/4-20 bolt I cut the hex head off. Then I chucked it up in my Lathe and turned a 35 degree point on the end. That's the same angle at the tip of the needle. Then I turned it back about a 1/2 inch so it just slides into the needle port. I put it in the port and taped the end of it with a small hammer that left a 35 degree cone where the needle seals off the fuel. Now it works perfectly every time!
