0-360 flames out of exhaust?

Last night took the family out for a night ride, while running dwn the river noticed flames shooting out of muffler tips like a blow torch. Is that normal on an A/V engine?

Can you send a pic. If I pay for shipping would you send them too Texas?

Headers

Where is a good place to get exhaust headers for a 0-360?

Re: Update overheat and detonation ! Thank you!!!

Flounder, Cool, glad to hear it. Now you know what you are working with. That is a hell of a big a## boat for a 4 cylinder aviation motor to push, can I assume you are fishing the flats vs. a bunch of dry running? If so, that is a good, economical motor for sure, but it is going to work. With a goo...

Re: Overheating and detonation

Flounder, I agree with that plan, particularly using a buddies tail number (or a made up one as suggested). At $500+ per cylinder, AV gas is pretty cheap in my book! Getting it is the hassle. I do keep a couple of bottles of Octane boost and lead substitute in the boat, just in case I need to bum f...

Re: Overheating and detonation

Flounder, I was in the same boat as you a couple years ago, with my first AV motor. So I have been through this (and other) learning curves. I am attaching some documents that were useful to me. The timing box is useful to check the timing by yourself, otherwise you need 2 feeler gauges and a helpe...

Re: Overheating and detonation

Assumption #1: You just got the boat from some one and don't know more. Assumption #2: The motor is mechanically sound (valves, etc.) Assumption #3: It's an aircraft motor, so it was set up to run on AV Gas (see #1).

Re: Overheating and detonation

if ya don't or cant run avgas there will be an issue with heating maybe not severe but still an issue especially if the timing and the carb are all set as if you were supposed to be running avgas....the airport where I get avgas told me the same thing...told him I don't have a plane then he said he...

Re: Overheating and detonation

What do the plugs look like? A clear pic of them organized by cylinder may help. Numerous times I have seen 1 (or more) cylinder not fire which made the other cylinders work harder, get hot and detonate badly under a load. I will pull them and take a picture, and get back with y’all. Sent from my i...

just cause the l/r lever is in full rich doesn't mean the shaft in the carb is in full rich UNLESS the positioning pin is in the lever...then ya know for sure mabye...cause there is always the chance that the shaft inside the carb has twisted or broken off and the lever is doing nothing.....the 036...

I would look at fuel/air or timing related...maybe the wrong carb, lean/rich lever not on full rich, intake leak, timing or mags not in sync.....had one doing that here a while back and found out that the lean rich lever was put on with no positioning pin and the engine was running terrible lean an...

Overheating and detonation

I am new to the AV engines, I have an 0-360 on my rig, after about 30 min of running it overheats and detonates bad. Need a direction to start looking for the issue. Thanks
