So I dunno if it's cause it's hot or what but flooded the 3.7 for the first time. Couldn't fire it up. Ran it briefly last week so dunno. It's pretty freaking hot and humid.
It could be due to the heat.
If you have any crud under the metering needle in the carb or the needle is old and not sealing well under pressure. The heat will cause pressure to build in the fuel tank and force the fuel past the needle and it will end up in the crank case.
Instant flood.
