I just purchased an m37 that sat for the last four years. should I try to clean the carb before I try to start her or should I just see what happens?
Thanks,

I pulled the top off of mine and checked to see if there was a bunch of junk in it.

I was able to get it to sorta run, but the carb was in bad need of a rebuild, which I did later.

I'd at least shoot some carb cleaner into every hole I could get it into.

The smart route to take is to go ahead & attend to the obvious first. You said it had sit for 4 years, the obvious being, rebuild the distributor, rebuild the carb, rebuild the fuel pump (may well keep from dumping gas into the oil pan), clean the fuel tank & replace all filters. Blowing out the lines is also wise. Check out the spark plugs replacing same if the need is obvious, check the cables for continuity. Change the engine oil & filter, be sure the radiator is full & give it a spin hoping worse problems don't become evident.

Thanks for the advice.
I am planning on doing a frame off resto. I am hoping to get it running good enough to see if a engine rebuild is needed.

After sitting for an extended period, it will need to run a while with some fresh oil to free up the rings before attempting a compression test, otherwise you are subject to getting an inaccurate test result. That's about the only way unless you plan to rebuild it during the initial restoration in which case no test is necessary anyway.

Charles,
Thanks for the info. I hope to get by without doing the engine, but if need be I will. The added cost will just extend the time it will take.
Thanks again,
