You must have had dirty fuel. I love my continental injection on my four cylinder got it from jt540 and he was awesome never had a problem only thing that is aggravating is having to pump the primer ball to start it! Plus injection is just plain bad ass!

Want to say thanks to JT540 for taking the time to talk to me today and answer my questions.

What kinds of problems do they have that makes them hate it??? Trying to get as much info as possible so I can make a decision. There's always pros and cons to anything you do to any engine. Just have to weigh them and try to make an educated decision.
Mainly starting and idling problems . But if you spend the money and some new or rebuilt parts and pumps you might be ok.

I had a lycoming injection system that came with the boat. I had nothing but problems with it. I beleave the system was a rsa. After spending a day cleaning injectors I threw in the towel, drove to the local airport and paid 1300$ for a new ma5 carb. Have not had any worries sence and never saw any performance difference. I also went from injection to carb on an io360 in an experimental aircraft and again never saw any performance issues. Although both motors would start a lot easier with carb especially when hot. I never had a chance to run a clunkanickel system but am a firm beleaver in keeping it simple.

The Lycoming injection is completely different from the Continental injection that rudee116 is considering putting on his boat.

Yeah...I wouldn't put the Lycoming system on it. Not even an option. It's either the Cont. system or get the proper carb. The reason I'm debating at all is we don't think that the boat has the right carb on it now. It is burning way too much fuel. It always has but my buddy didn't realize it cause he hardly ever goes through a tank. Just runs to camp and back. We took the boat duck hunting & scouting last year and figured out that is just swallowing fuel.

Anyone tell me what carb you're running on a 300 upstack 540? Seems like the closest motor that came with a carb is the VO540 that came with the MA-6 (thanks for the info JT540!)

Both are great injection sytems. The bad publicity that injection gets is because ALOT of the stuff people are getting are wore out junk. RSA systems are a beast when there right, and the only way to get them right is to calibrate them on a flow bench back to Lycomings specs.

Anyone that wants to junk there injection for a carb please let me know!

Burning a lot of fuel could be a few different things. Prop, hull not running free. What kind of hull & prop are you running with what kind of cruise RPM ?

The only reason i recommended the ma6 4401 was because it was designed for a vo540c2a 310hp @3200rpm thats seems to be the closet match the 4404 is a great all around carb and seems to work on everything!

Just wondering, are you guys taking off the A/V injection sump to install a smaller s/v sump and a 260hp carb on a 300hp engine?

Its not your setup its your carb someones been in there playing with it and got it out of wack. Find out the p/n and let me know. If you have a ma 6 now it most likely just needs a overhaul and adjustment!

Someone tell me what it mean if the ID plate on the carb has XXXXX stamped on it?? The numbers on the plate can't be read. Is the part number stamped somewhere else too? I'm trying to figure out if I can trade it in as a core.

they wont take it for core because its probably got so many mismatched parts inside the couldnt rebuild it.

Food for thought - We are working on a very reliable affordable electronic fuel injection and have prototypes running great now. Also have electronic direct fire ignition based on GM parts. Single system can also run both. More to come. Not totally ready to release just yet.

av and carbs don't belong together
Tell Lycoming. TO-360-C1A6D 210 hp/ TO-360-A1A6D 200 hp/ TO-360-F1A6D 210 hp/ VO-540 series, most with 300 or 300 plus hp. All run carburetors.
Compromise is failure on the installment plan.
