found a carb rebuild kit with the proper float bowl gasket, all the ones on amazon that i saw had a round hole where the fuel enters but the tohatsu gaskets have that indent for the screw hole and not a bad price
ordered a 6 liter ultrasonic cleaner and am going to try pinesol as the solution...
under load it feels like its not getting enough gas, from what ive read there isnt any adjustment screws on these carbs. was out trying full throttle and it was bogging down then after about 15 minutes it sort of cleared but then it feels like 3/4 throttle. somethings not quite right it wont...
looking at manifolds and am thinking i might be better off with a new manifold
the firing order is 1-3-4-2
i think the dual carbs were only one year/1968
1 carb did cylinder 1&2 the other carb did cyl 3&4
the manifold below from 1964 to 1972 changed what cylinders were served by each barrel
1...
ok, so each barrel could serve 2 cylinders through the divided intake manifold off of one set screw and it would be fine unless one of the ports got fouled.
thank-you
was trying to find the cfm of the carter rbs carb but cant find it
even looking for the cfm of a merc tks i got nothing
found a cfm formula for engines
cid 153 x max rpm 4500 x efficiency(typically 80%
550,800 cubic inches
divide by 3456 for 159.375 cubic feet per minute (cfm)
this 120hp engine...
im missing the dual single barrel carbs on the manifold but i have the 140hp merc carb
im thinking of just grabbing a couple flanges and plumb it to each barrel of the 140hp carb
my question is this
the merc carb is 2 barrel, does each barrel act the same or does each barrel have a special job?
i thought it just meant it was the EU version of the carb
which in your opinion is the better carb
the merc, tohatsu or yamaha carb
i think i read somewhere here that yamaha could be used also?
this carb has the accelerator pump on it where the old one didnt. bolted up just fine, fired right up. had to adjust the idle screw and the accelerator pump screw a little. no complaints so far
Had it running good last year, then he left the gas tank connected in the hot sun with vent closed and gas would pour out the bowl gasket. Im not going to toss the tohatsu carb, ill rebuild it but its just a matter of getting this motor running asap. My son got a job at the marina and needs it...
i need to rebuild my carb but i cant get a tohatsu kit/3v1-87122-0 locally, im in Canada and the local shop said the Texas warehouse is out of stock.
boats.net has a genuine tohatsu carb kit but it wont let me check out and the page freezes, i think because im in canada theres an issue...
