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

the 290...125hp stock uses an MA-3SPA carb ….I believe the biggest engine to use that carb is the C-145 Continental but I don't see a lot of improvement in performance with just a carb change....jmo

imo…..the new autolite #386 nickel plated....gapped at .022-.024

I work on bendix mags but i am little far away in lake placid

usually the main nozzle/jet is the only difference......I cannot find that 10-2153 number carb any where in the Marvel Schebler book...imo the best carb for that engine would be the #3 carb for an 0-200 cont or an 0-235 lyc….both produced the same hp and rpm as the franklin...knowing that I do have ...

looks like a narrow deck straight valve 0-360 Lycoming....with a really piss poor spark arrestor set up...lol

carb for the 4ac-199 and 0-200-1 is an MA3P....10-2302

buy a right handed gig and just turn it over 1/2 turn...waaalaaa left handed gig...works every time

I agree with diesel250….if ya have fuel, air, spark and compression and it wont fire I would look at the engine/magneto timing

welcome to the world of Frankenstein mags and carbs.....all the cases in the 20/200 series are basically the same ...the tags are from factory assembly......the s6ln-23 mag is oem on the 220 gpu but can easily be converted to a 4cyl mag by changing internal parts and the setup....so to answer your q...

I tried to e-mail ya ...wouldn't go thru.....the 0-360 does not use a 4spa they use an MA-4-5....gonna try the e-mail again

just curious....where is the generator mounted on the 290 GPU engine?

I had a 3 blade warp on a 65 cont on an old wildcat 11' hull I used for duck hunting..it worked great and no it would not run the hill...

I picked it up years ago from an A&P friend .......there is one for sale on e-bay #7446...but it may be for the smaller carbs not sure without looking it up ...try messaging twister here on SA ....he may be able to help ya out

I do not have the 1 piece that ya need but I do have the tool used to remove and install the 1 piece venture....it takes a hand press to use it.....but I bet someone on SA has what ya need

the man is exactly right MA-3SPA.......... but make sure ya get the right part number for the 0-290 some of those carbs are for much smaller hp engines

IMO....there is nothing more fun to run than a light, free running little sled with a rank 200lyc....but like Gary S said be smart on the load and don't bring the neighborhood...but damn they are fun!!!!!

it is really hard to give a definite reason but if ya ever drive one (a good free running no hop rig) then you will know the reason....

1/4 x 20...make sure ya use a short bolt on the 2 holes that are in the bowl so ya don't punch a hole in the bowl bottom or put 1/4 x 20 studs in those holes

I think the rears are automotive transmission mounts....like Bob said I never seen a 360 with that type of nose mount before......learn something new everyday

aircraft spruce.....got many many cht gauges and sending probes and thermocouples at a wide range of prices
