Choking an 813
Quick question for all the 813 carb owners and those that know. How do you choke an 813 carb. I have one on one of my boats and I just put my thumb over the intake to choke as do most boaters because most carbs that are on boats don't have chokes. Doing the same on my 5t won't help as there is a filter in the way that is a pain in the you know what to take off. So what's a guy to do?

RE: Choking an 813
Yup, the carb has an accelerator pump that squirts enough gas into the carb so to prime it. Only problem is that accelerator pump is not always reliable. Mine failed right away and took about 20 pumps to prime, then fail altogether. I switched to a 668 carb with a built in choke and never had any more problems.
While people that have working 813 carbs defend them, I have found them failing too often for me to be able to appreciate them.

RE: Choking an 813
i ran nothing else for the last 2 years , great carbs but they have a short life span in dirt, ( I'm now back with 668's after going thru about 6 813's...still have one on my pig but it's now starting to flood which means it's the end of it's useful life)...with the 813 the shaft, piston and pump circuit wear out after a while and then it's time for a new one.
after mounting it make sure you silicon the half hole that's left exposed near the top on the side that faces the motor and closest to the linkage arm on the shaft...it's the hole the ball and piston slide into and needs to be sealed up to prevent premature wear of the shaft and pump
