Irvine .53
Just picked up an Irvine .53 today. Good compression, should be a good engine, however the previous owner said that it refuses to shut down with the carb barrel completely closed off. Must be an air leak somewhere.
I was wondering, will the red finish of the engine stand up to an antifreeze bath? Or will the AF remove it along with the old gunk on the engine?
Thanks!

RE: Irvine .53
Having 6 irvine 53s and all convereted to diesel (davis heads) no issue the jetstream carb is one of the best,, you have 2 sources of air leaks the o ring on the carb needle and the main o ring on the
carb body may be dried out and leaking, replace them and the issue will be solved I use a touch of copperkote sealer on the main o ring just to be safe, you can "crock pot the engine
but this is not the issue it will look nicer but the o rings are the answer, have never had the problem with these engines the carb barrel is a tight perfect fit smooth, and not a leak source martin

RE: Irvine .53
From what I hear, the crockpot treatment will strip the red powdercoat right off. Alcohol and a toothbrush might be the best for getting that engine clean.
