That's why I post on hear things I did not think of. Is there a fuel drain screw incase water is in bowl I believe I have a ma6? not a 4-5. I know if water gets in the bowl that that can stop it from starting. there are actually 2 bowl drains on the MA-6AA carbs one on each side if the fuel shut of...

yea I agree....bet that little carb needs a good cleaning and some tlc

holy cow 10 pumps on the throttle....should be fuel running all over the place if the accelerator pump circuit is working properly

try this sequence to start the engine cold....it is what I did to start mine when I lived in Nebraska.....turn on fuel pump to fill carb....slowly pump the throttle pedal 2 times....hold the pedal down after the second pump....with mags OFF turn engine over several revolutions....return pedal to idl...

friend of mine had that issue on his GO-480 and it was an intake leak

that is great!!!....thank you

if you have the tall lean/rich lever that swings in near the top of the carb they actually make a return spring for it that bolts right on the carb

you can never have enough good spare parts for these engines....I have a pretty good inventory of aircraft carb parts and Bendix mag parts so if ya ever need something just let me know....got everything shipped est del date is thurs the 3rd...good luck

looks like ya need a bowl gasket too....I will send ya 2 floats and a bowl gasket if ya pay for the shipping....you are right about the 3878 carb the other carb of choice for the 360 engine is the 10-4164 -1...….ya just never know what your gonna find in and on our airboat engines....all the #187 th...

I don't have an inlet screen but give me your address and I will send ya a float and for your information that carb is off a 165hp franklin engine and may be just a little short on performance for the 360 unless someone put in the 360 atomizer nozzle/jet....is your float silver, brass or solid black...

that tells me that if you pump the gas and it helps that it is giving the engine fuel thru the accelerator pump but not thru the main jet/nozzle....the idle jet runs the engine to about 1000rpm then the engine draws fuel from the main jet and if it wont run above 1000rpm without pumping the gas peda...

kind of sounds like the main jet/nozzle is clogged...….when the engine starts to stumble and die what happens if you pump the gas pedal?

just get the number off the old seal and match it up with the new one

I always thought the one big advantage to the electronic ignitions was the timing advanced as the engine needed it.....if they tell ya not to use it and have a fixed timing at 25 degrees wouldn't ya just have an expensive glorified magneto ignition ?

my 360 has had the long studs removed and a 1/4" thick plate with a gasket and four 1/4 x20 bolts to hold it in place

sounds good...ill take care of it for ya

those are 1200 series mags and should spark big time by hand no drill needed if they are right....I run them on my 200 and they are really hot when they are setup right but they are a different animal to setup than the 20/200 series mags.....send them with the carb and ill get'em right for ya...you ...

hell yes man send it to me and I will take care of it and send it back to ya with the parts that ya don't need or are wrong...….some float numbers have been superseded by new numbers not a big deal ….take about a day...….greg mccloud 4 Henderson rd lake placid fl 33852

my neighbor has a 220/520 engine (not gtsio cyls) and has the 500 holley carb and it runs perfect and is easy to tune...it has the log intake with an inverted "Y" with the carb right out in front of the mags

slick is a brand name not a type of mag...impulse is a mag that retards the timing to fire the engine.....shower of sparks is used in place of the impulse coupling assembly......I remember waaay back when an impulse mag was refered to as a Bendix and a straight or non impulse mag was referred to as ...

if that is the Circle H hulls from Alabama my buddy has a 12 footer with poly and it is a really good hull, runs fine no hop no trim tab ...but it is not cut down and has a DD carmotor on it though

IMO.....when this kind of thing happens.....sell your mags and wires put a pacemaker ignition on it and never look back

if ya got a problem and ya think it is the carb and I rebuilt it ….send it back and I will see what I can do to figure out what is wrong and make it right.... no problem

what carb are you running.....10-???? on the id tag

if the problem is when the engine is hot or at wot it may be a coil issue
