Saving Old Seagulls

im trying to revive a wscl 721dd8 with an amal carb, i want to mix and match parts from a sl 2081d9 with the amal carb. both barbs appear to be identical, are they? ( the threads are stripped where the float bowl attaches to the bottom of the carb on the wscl, and i want to use just enough parts from the sl to solve the problem)

thanks

They are both Century motors, same CC and hp, Would say they are the same.

thanks keith, im going to try it now, the carbs do measure up as identicle, just didnt want to find out the hard way that i was wrong.

Have a look at the jets. The 1978 motor may well be jetted for a different fuel mixture.

There are little numbers stamped on the jets. If they're the same then no problem; if they're different then the later one will be 25:1, the earlier one 10:1

thanks guys.
i hate to ask stupid questions, but where do i find the jets in the amal carbs? my other bs motor has a needle and has been converted to 25:1. ( im new to gulls, and dont want to ruin the ones i have!)

This should help.

thanks keith, that is exactly what in needed! (now when i ask more questions...i will be able to use the right terminology)
.....is there an easy way to remove the jets without having the tool?

thanks

Don't know if it will work for you, depends on what you have, but it use a radiator key.
