First off-season on alcohol. “Winterizing” tips?

[demon322]

Hello all. Made the switch to alcohol last summer so this is my first winter not on race gas. Wondering what all you guys do to protect your carbs and fuel systems and help be ready for next spring. I have heard some say wd40 and others mention marvel mystery oil. Do any of you remove the carb completely? Or just try to make sure it’s cleaned out as much as possible. The last time I had a bowl off for jets change I noticed some slight white chalking starting to develop.
1050 carb, Magnafuel 500 pump with filter.

Also, do any of you back off your rocker arms during the off season?

Thanks!

I remove and disassemble the carburetor, and spray everything with WD-40. I also spray all the cylinders and the intake manifold tracks with WD-40. I turn the engine over by hand and then back off all the valves. I will also take the electric fuel pump apart, clean and spray it also. Even racing fuel is corrosive, I have seen the underside of throttle blades and intake valves get rusted from racing fuel

What we did was added a mixture of top lube through the system and run it

Thanks for the tips! So do you then leave the carb apart and WD coated until spring? Spraying the cylinders seems like a good idea also. And you do relieve some valve pressure so that answers that question.

I was going to look at the removable filter on the fuel pump. Sounds like cleaning the pump itself is a good idea also.

Thank you

I added some top lube to my fuel barrel when I got it, is that what you mean? Sorry, still learning!

I lent a carburetor to a friend of mine, and he sold the car. So he had bought another carburetor, and gave it to me. This carburetor had been sitting around with old fuel in it for awhile. The accelerator pump diaphragms were solid, every gasket is stuck on. So I am cleaning everything, and leaving it disassembled. But normally, I have them back together and ready to use.

Ah, gotcha. That makes sense. Thank you
