Float bowl crack

[two stroke mick]

Hello all

I have found that there is a crack in the float bowl of 15 hp Johnston 2 stroke. The crack is as a result of an overtighted screws. Due to the location of the crack it is not possible to repair from the outside. I am seeking a temporary repair solution. The crack could be sealed on the inside of the bowl. The bowl is plastic.
Is there anything that can be used to effect such a repair?
Any suggestions as to where I much get a replacement float bowl

Regards

Hi ,no expert on these things but seeing you have no ideas ,i will offer that in the past for a very tempory repair to plastic things ,i have gently stroked the plastic with a hot soldering iron !! melting slightly accross the crack with lots of success ,but very gentle as too much heat just once and your buying new

Have repaired a fuel pump body which was hard plastic with 2 part epoxy putty, was damaged at sides, still working top.

I carried out a second strip down of the carb this afternoon to allow for the taking of a photo as suggested. There is a crack in the bowl but it is only on the outside lug where the holding bolt is located. I studied the bowl some more and found no crack in the important part of the bowl. What a difference natural light makes. I cleaned the various gubbins and clapped it back together. Tank tested the engine under load for two hrs low slow trolling speed. The engine ran well. I hope I have fixed the problem of stall and cutout at low speed along with difficult start. Thanks once again to dinner.
