My mechanic tells me, that if we go through an overhaul on the carb, the boat will still have hesitation problems. If I go to the electronic choke on a new carb, it would go away.
While TKS carbs do have their issues, this statement tells me the mechanic is in name only, and really does not understand the issue. You can take a standard 2 barrel carb with electric choke and it will work
fine (
note the fine, it will only work fine provided it is setup correctly and there are no other issues).
If their are no other issues with the motor, both a carb with electric choke, OR the TKS carb will run the same. The issue your describing is the motor is running lean when cold, so the TKS module is not getting power or its bad.
In the pic below the wiring shows that once the motor is started power turns on the fuel pump and also supplies power to the module. As the module heats up it closes off the extra fuel. Once the water temp is warmed up, a switch closes and keeps the module closed. Since it always runs lean your module I the issue.
Down to the facts.
Both regular and TKS will work if they are working as designed.,
The "
Mechanic" has already proven they either do not understand how the TKS works or they don't want to mess with it. Keeping the TKS means you need to fix it your self (
with help from us), or find another mechanic.
Changing to a regular carb may not fix all your issues if their are other issues.
Suggest if you go the route of changing to regular carb, ask the mechanic that "
If you change to this carb he guarantees, in writing, that all your issues with cold starting will be fixed". This way, your problem is fixed. My guess is they will not guarantee it
